Not only was the little Velodyne the best

small

sub I've ever used,

it was one of the very best subs I've used.

-John Potis

SoundStage!, April 2002

"The SPL-1200 was able to hit an impressively deep 16 Hz."

Tom Noussaine

Sound & Vision, June 2001

"How do they get this kind of bass out of such a tiny box? Deep, tight,

tuneful and loud enough to rattle pictures on the wall--this is serious

subwoofing."

-Robert Deutsch

Troubleshooting and Service

If you should experience a problem with the operation of your subwoofer,

please check all of the following before seeking service. Following is a

simple troubleshooting guide to assist you.

1. Verify unit is plugged in, power outlet used is active, and supplying

proper voltage.

2. Is power switch on?

3. Is auto turn on/off set properly?

4. Is unit receiving an input signal from your source?

5. Have all controls on subwoofer (volume, crossover, phase, etc.) been

properly set?

6. If unit has been running at high levels for an extended period of time,

one of the protection circuits may be engaged.

• Is the built-in amplifier extremely hot to the touch?

• Is your power line voltage sagging below acceptable levels?

If the protection circuitry is active, the unit may cycle on and off until

operating parameters return to normal. Under more serious conditions, the

unit may shut off completely. Normal operation should return upon

cooling, but you may be required to turn the power off and then on again

to reset the unit.

The following conditions require service by a qualified technician:

1. The power cord has become damaged.

2. The unit does not appear to operate normally or exhibits a marked

change in performance.

3. The unit has been exposed to water.

4. Some part of the cabinet or circuitry is physically damaged.

• Signal sensing auto turn on/off (defeatable)

• Variable volume control

• Selectable phase control (0

or 180

)

• Frequency response of 28 - 120 Hz (SPL-800 Series II), 24 - 120Hz (SPL-

1000 Series II), 22-120Hz (SPL-1200 Series II)

• Magnetically shielded for video use (SPL-1000 Series II and SPL-1200

Series II)

• Multiple staggered low-pass crossovers; 12dB/octave initial, 48dB/

octave ultimate

• Driver Displacement Control circuit prevents over excursion and amp

clipping

• Blue power indicator LED

• High-excursion EPDM rubber surround

• Oversized spider for linearity at high excursion

Prepare for Installation

Your new Velodyne subwoofer provides for a number of installation

options. Read all the installation information below in order to determine

which installation option is best for your system. Remember to perform

all installation procedures with system power turned off to prevent

possible damage.

Placement

True subwoofers operate at extremely low frequencies which are primarily

omni-directional. While it is recommended that the subwoofer be placed

on the same plane as the satellite speakers, room and system conditions

often dictate otherwise. Keep in mind that frequency response and output

level can be drastically influenced by placement, depending on the

acoustic properties of the listening room. Typically, the optimum location

Care of Your Subwoofer

Your Velodyne subwoofer does not require any regular maintenance.

Normal dusting or cleaning of the surface for appearance purposes are all

that is required. We suggest you avoid any harsh detergents or chemicals

when cleaning the cabinet. Abrasives, detergents, or cleaning solutions

may damage the finish on the cabinet. We recommend using only a damp

cloth to clean the cabinet.

During normal conditions, your new subwoofer may be left on continuously

without any problems. The unit is equipped with a signal-sensing turn on/

off that will automatically turn on the unit when a signal is present at the

inputs and turn off the unit after several minutes when there is no longer

any signal at the inputs. If you plan to leave the subwoofer unused for an

extended period of time, we recommend that you turn off the master power

switch on the rear panel.

The unit is protected against:

1) Overdriving the speaker or amplifier.

2) Overheating the amplifier.

3) Excessive drop in power line voltage.

The first type of protection circuitry which prevents overdriving of the

speaker or amplifier operates constantly without being audible under most

situations. In some extreme situations (sustained high output levels such

as pro sound usage), the unit may shut down momentarily. This indicates

operation of the thermal or undervoltage protection circuitry. If this should

happen, you should reduce the volume setting or shut the unit off until

normal operating conditions return. You may also want to plug the unit

into a different wall outlet, as dropping power line voltage will be most

noticeable under strenuous conditions and may result in the unit shutting

down intermittently.

Protection Circuitry

Your new subwoofer is equipped with special protection circuitry to

provide maximum performance with greatest reliability.

strands or frayed wires which may result in a short, which may damage your

equipment. Cables of extremely large size are typically not required.

Extremely large gauge wire may not properly fit in the binding posts,

resulting in a poor connection and possible short circuits.

continued. . .

Regardless of where you install your Velodyne subwoofer, it must remain

in an upright position (woofer facing forward). Using, shipping, or

otherwise storing the subwoofer in any other position for an extended

period of time may result in damage to the unit not covered by warranty.

The SPL-1000 Series II and SPL-1200 Series II are magnetically shielded to

reduce the amount of stray magnetic energy emitted from the speaker's

motor structure. This greatly increases flexibility when placing the unit

close to video monitors as there is very little stray magnetism. Certain types

of televisions are particularly sensitive to stray magnetic fields. If your

television produces distorted colors after installing your subwoofer,

simply increase the distance between your television and the subwoofer,

until normal color and operation is returned.

Your new Velodyne subwoofer, like any good speaker system, requires

proper positioning within the listening space to provide maximum

performance. Improperly placed speakers may degrade the sound quality

and reduce your listening pleasure. Depending on the size and type of

furnishings in the room, perfect placement may not be possible. Finding

the best location for your environment will likely require some

experimentation. We suggest you experiment with the location during

setup to find what sounds best to you when seated in your typical listening

position.

continued. . .

☞

for a subwoofer is tucked away in a corner of your listening room. This

location will usually offer the greatest output levels and optimum low

frequency extension. The worst location for a subwoofer is typically far

away from any walls, and close to the center of your room. Avoid these

locations when possible. When using a pair of Velodyne subwoofers in

stereo, it is preferable to place each subwoofer by the satellite of the same

channel.

Caution! This subwoofer has electronics built into the cabinet. Do not

place the cabinet next to sources of heat such as furnace registers,

radiators, etc. Do not place the unit near sources of excessive moisture,

such as evaporative coolers, humidifiers, etc. The power cord should be

routed in such a way that it will not be walked on, pinched, or compressed

in any way that could result in damaging the insulation or wire.

Installation

Inputs

Your new subwoofer is equipped with speaker-level and line-level inputs.

Use the LINE LEVEL jacks when connecting your subwoofer to a pre-amp,

signal processor, line-level crossover, or receiver with pre-amp level

outputs. The SPEAKER LEVEL jacks connect directly to the speaker

outputs of any amplifier, integrated amplifier, or receiver. Your amplifier

section will notice no additional loading effects when you use these inputs

due to their very high impedance.

Important!!!

Do not use both LINE LEVEL and SPEAKER LEVEL connections

simultaneously!

Volume control

This control allows you to balance the output from the subwoofer to the

main speakers/amplifier in your system. This control should be set to

achieve similar output level from both the main speakers and subwoofer

when listening to music. A good starting point for the volume control is

3 or 4 dots from minimum.

Low-pass crossover - 40 to 120Hz

All inputs sum the left and right channels together, with the resulting signal

passing through an adjustable low-pass crossover before being amplified.

The crossover control allows you to adjust the upper limit of the

subwoofer's frequency response from 40 to 120Hz. The subwoofer's

response will begin rolling off above the frequency you set this control to.

You should set the crossover frequency to obtain a smooth and seamless

transition from the subwoofer to the main speakers in your system. If your

main speakers are smaller units with limited low frequency output, you may

wish to choose a higher frequency (such as 100-120Hz) than you would

with larger speakers which have greater low frequency output. With larger

speakers, you might start with this control set lower, such as 80Hz.

A bypass switch is also provided if you wish to use an external crossover.

If you are not using an external crossover, we recommend that you use

the one provided within the unit for optimum performance!

Phase adjustment - 0

/180

This control allows you the "reverse" the phase of the subwoofer's output

signal 180

to correct for any possible mismatch and resulting cancellation

continued. . .

☞

To bypass the subwoofer's internal crossover when the unit is being fed

a low pass signal from another crossover, simply locate the switch marked

INTERNAL X-OVER/SUBWOOFER DIRECT on the rear panel of the

subwoofer and set to the SUBWOOFER DIRECT position. This will

eliminate the internal crossover from the signal path.

Speaker-level Connection

Figure 3 shows an easy way to connect your Velodyne subwoofer directly

to your receiver or integrated amplifier, if it lacks line-level outputs. You

may also connect your satellites directly to your receiver or amplifier along

with the subwoofer. Your receiver or amplifier will not notice the additional

load of the suboofer due to the high input impedance.

Caution!!! To avoid damage to your main amplifier, be sure to maintain

correct polarity when making all connections. Red (positive) to red, and

black (negative) to black. Be sure that all connections are tight, and that

there are no loose strands or frayed wires.

Interconnect Cables

When installing your new Velodyne subwoofer using the line level

connections, you should always use shielded phono cables. There are

many decent cables available today, most any of which will work perfectly

well. We do recommend that you keep the length of cable as short as

possible to avoid any potential noise problems.

When using speaker level connections, use a decent quality speaker cable

that mates well with the connectors. Be very careful to avoid any loose

The Velodyne subwoofer is designed to operate using the full range audio

signal for input when using the built-in crossover. Many home theater

processors/receivers (Dolby Digital, DTS, THX) have a "subwoofer out"

jack that is internally filtered and designed to be used with a powered

subwoofer. In these installations, you may bypass the internal crossover

in either the processor or the Velodyne subwoofer. In some installations,

it may be beneficial to have a steeper ultimate crossover slope. To do this,

you can use both your processor's crossover and the one internal to the

Velodyne sub. You should stagger the frequencies, (i.e., 120Hz sub, 80Hz

processor) for best results.

signal through external processors with a crossover circuit of their own,

such as the new digital units. Simply move the switch to SUBWOOFER

DIRECT to disengage the built in crossover. For all other installations

which do not have a separate electronic crossover, we recommend you

leave the switch set to INTERNAL X-OVER to provide optimum

performance.

Auto turn on function

With this function in the "auto" position, your subwoofer can be safely

left with the main power switch on continuously. The subwoofer will turn

itself on automatically when an audio signal is present. If no signal is

present for approximately 10 minutes, the unit will switch to standby mode.

While in standby mode, your subwoofer will draw very minimal power.

This function can be disabled by leaving the switch in the "on" position.

Power switch

The master power switch is located on the lower half of the unit. This rocker

style switch is the main on/off for the unit. This switch should be set to

position 1 (up) for on, and 0 (down) for off. If the unit is to be left unused

for an extended period of time, the master power switch should be turned

off.

Subwoofer outputs

The Velodyne subwoofer is designed to operate using the full range audio

signal for input when using the built-in crossover. Some processors/

receivers, have a "subwoofer out" jack that is internally filtered and

designed to be used with a conventional amplifier and speaker. In some

rare cases, combining both an external crossover and the one internal to

the subwoofer may result in low output and increased noise. In these

installations you may need to bypass the internal crossover in either the

processor or Velodyne subwoofer. In some installations, simply setting

one crossover to a higher frequency (such as 120 Hz) will restore maximum

performance. To bypass the subwoofer's internal crossover when the unit

between the subwoofer and your main speakers/amplifier. To adjust,

simply listen to the system with music playing. Then move the switch from

one position to the other and listen for a change in low frequency output.

The correct position will have a greater amount of apparent low frequency

output.

Crossover switch - INTERNAL X-OVER/SUBWOOFER DIRECT

This switch allows the electronic crossover circuitry to be removed from

the signal path. This is required in certain installations which route the

is being fed a low pass signal from another crossover, simply locate the

switch marked INTERNAL X-OVER/SUBWOOFER DIRECT on the rear

panel of the subwoofer and set to the SUBWOOFER DIRECT position.

This will eliminate the internal crossover from the signal path.

Note: If not using an external crossover, you should use the built-in

crossover for optimal performance.

Line-level Connection - Option A

Figure 1 shows connection from your home theater receiver to the LFE

input on the back of your subwoofer. When the subwoofer is installed in

this fashion, all of the low frequency information from your "LFE Out" or

"Subwoofer Out" on the back of your receiver will pass into your Velodyne

subwoofer. This connection is the most common connection method

when using your subwoofer with a 5.1 receiver. (Cable needed: 1 mono

RCA cable.)

Note: If not using an external crossover, you should use the built-in

crossover for optimal performance. When using a single channel input

(such as a surround sound processor's subwoofer out or LFE), the auto

on/off circuit sensitivity will be affected. When one input channel is used

instead of two, the unit will see lower signal levels present at the inputs.

This may cause the unit to turn off when listening at low volume levels.

If this occurs, simply use a "Y" adapter (available from most dealers) to

allow your processor's single sub line to be fed into both L&R inputs.

This will make the unit turn on at lower signal levels.

Line-level Connection - Option B

Figure 2 shows connection from a pre-amplifier's main outputs to the left

and right inputs of your Velodyne subwoofer. You will also need to

connect a second pair of RCA cables from the outputs on the back of your

subwoofer to the inputs on the back of your amplifier. When the subwoofer

is installed in this fashion, your satellite speakers will be crossed over at

80Hz which removes the lower bass from frequencies from your external

amplifier and speakers, enabling them to do a better job reproducing the

higher frequencies. By utilizing this method, you will have a bi-amplified

system, gaining improved power and headroom for your system. This

installation method is not as common as the method described in Figure

1. (Cable needed: 2 stereo pair of RCA cables.)
