SETTING UP THE S•3-way

Whether you are an experienced audio engineer or just starting out, the next sections of this manual will help you

get going with your S•3-way. Now that you have unpacked the unit and have become a bit familiar with the front

panel controls, you can follow the next sections of this manual to begin to set-up and operate your new

crossover.Further on in this manual, you will find detailed wiring diagrams of various speaker system set-ups.

For detailed diagrams of connector and cable wiring, see page 15 in this manual.

MODE SWITCH

The S•3-way can be configured to operate in several modes

including Stereo or Mono 2-way, Stereo or Mono 3-way and

Mono 4-way. In addition, the S•3-way has a special operating

mode; 4-way LOW which is used for ultra-low sub woofer appli-

cations. The Mode Switch, located in the center section of the

unit, is used to select the operating mode. As you switch through

the various operation modes, you will notice that several LED’s

on the panel are also changing. These are the Mode Indicator

LED’s and they help you keep track of the changing controls.

FREQUENCY BAND & LIMIT INDICATORS

Because the S•3-way can be configured to operate in several different size sound systems, the crossover con-

trols may be adjusted for the frequency division between low, and high, or low and low-mid, or high mid to high

depending on the mode. On some crossovers, it is very difficult to get a quick visualization as to what controls are

controlling what function. The S•3-Way solves this problem by employing it’s Mode Indicator LED’s over the

Frequency and Gain controls. These provide quick identification of the frequency band that is under control. In

the diagrams below, you can see what functions are under control when the associated LED is lit. Also, over each

Gain control is an LED that illuminates indicating that frequency band has entered into Limiting. More information

on using the Limiter can be found on page 10.

Operating the S•3-Way

SETTING UP THE S•3-way FOR STEREO 3-way OPERATION

The following operating example is for a Stereo 3-way system using 15" sub, 12" mid range and 1" compression

driver and both the left and right side. There are systems examples for other set-ups including stereo 2-way and

4-way mono operation.

CAUTION:

Before you apply power to your speaker system amplifiers, be certain to set the frequency controls to

the manufacturers recommended crossover points for the drivers or enclosures you are using.

NOTE:

LAST ON / FIRST OFF

When running a loudspeaker system with one or multiple power amplifiers, it is highly recommended that you fol-

low the LAST ON / FIRST OFF rule. When powering up your sound system, turn your power amplifier on last.

When you power down your system, turn your power amplifiers off first. This will prevent any switching spikes

you may get from other gear in your system, and help prevent unnecessary speaker damage.

• Connect both sets of inputs and outputs to the designated connectors on the rear panel. For a detailed

cable-wiring diagram see page 15.

SETTING UP THE S•3-way FOR STEREO 3-way OPERATION (Continued)

• Connect the mixer’s left output to the S•3-way’s CH1 (Left) input and the mixer’s right output to the S•3-

way’s CH2 (Right) input. Now connect the S•3-way’s CH1 (Left) Low Output to the left input of the low

end power amp, CH1 (Left) Mid Output to the left input of mid-range power amp, and (Left) High Output

to the left input of High power amp. Now make the same connections for the S•3-way’s CH2(Right) and

amplifiers right side.

SETTING UP THE S•3-way FOR STEREO 3-way OPERATION (Continued)

• Lower your power amplifier outputs to all the way off. Turn on all your power amplifiers. Run an audio sig-

nal (like some music from a CD) through your mixer and raise the output faders until you see the Input

Meter LED’s begin to light.

• Slowly raise the S•3-way’s Input Gain until the Input Meter reads 0dB.

• Now raise your power amps to their normal operating level.

• Slowly raise the S•3-way’s Ch1 (Left) Low Gain to 0 and then raise CH2 (Right) Low Gain to 0.

• Slowly raise the S•3-way’s Ch1 (Left) Mid Gain to 0 and then raise CH2 (Right) MID Gain to 0.

• Slowly raise the S•3-way’s Ch1 (Left) High Gain to 0 and then raise CH2 (Right) HIGH Gain 0.

• Now use your ears to adjust the balance between the low, mid and high end. You can continue to raise

the Gain controls as you fine-tune the system. Watch the Peak Meters on your power amplifiers to

ensure that you re running a clean signal.

S•3-way Controls

HIGH PASS FILTER

The S•3-way incorporates a HPF (High Pass Filter) which

when engaged, activates a low frequency roll off at 25 Hz. By

using the HPF you eliminate the sub-sonic frequencies sent to

the low frequency power amplifier. Since the amplifier will try to

reproduce these frequencies with the HPF is off, in most cases

the result is simply wasted energy. By using the S•3-way HPF

you send just the frequency you want to reproduce to your low

frequency amplifiers and speakers.

MUTE SWITCHES

The S•3-way features Mute switches on each

frequency band. When engaged, the LED illumi-

nates and that channel output is turned off. The

MUTE switches are convenient for trouble shoot-

ing or for simply listening to each speaker sec-

tion separately.

CD EQ SWITCH

Many of today’s popular speaker enclosures feature Constant Directivity Horns.

The S•3-way’s CD EQ switch can be activated to apply a special equalization

curve for smoothing and adding air to the high end of a loudspeaker system.

MONO SUB SWITCH

For easy operation of mono subwoofers, the S•3-way provides a MONO SUB

switch. When activated, the low frequency band of Channel One and Two are

summed together. The common low frequency signal is present at both Channel

One and Channel Two’s Outputs.

LIMITER

A Limiter is a specific form of a compressor configured to prevent peaks and for

general overload protection. The S•3-way offers a Multi-Band Limiter with vari-

able Threshold control. The operating range of the Limiter is from -5 to +18dB

and when engaged, protects against signal peaks and overloads.

Once you have your system wired-up, follow the steps below:

• Set the mode switch to the ST 3 W position. Notice how the BAND INDI-

CATOR LED’s change showing the frequencies that are now under con-

trol by the associated GAIN or FREQUENCY knobs.

• Look for the illuminated L/M BAND INDICATOR LED over the first FRE-

QUENCY control. Now, use the first crossover FREQ on Channel 1 to

set the desired frequency dividing the Low and Mid frequencies. Now,

use the second crossover FREQ on Channel 1, indicated by the illuminat-

ed M/H LED, to set the desired frequency dividing the Mid and High fre-

quencies. Repeat the same procedure for the Channel 2.

• Look for the illuminated LOW BAND INDICATOR LED over the GAIN control. Now, adjust the first gain control

on Channel 1 to set the level of the Low frequency output. Look for the MID BAND INDICATOR LED over

Channel 1’s second GAIN control to adjust the MID output. Adjust the High output using Channels 1’s third

GAIN control designated by the HIGH BAND INDICATOR LED. Repeat the same procedure for Channel 2.

SETTING UP THE S•3-way USING A REAL TIME ANALYZER

A REAL TIME ANALYZER (RTA) is an especially useful tool for setting up your crossover, as it will

enable you to set parameters like DELAY and LEVEL more accurately. Some Audio Engineers can use

their ears to tune a loudspeaker system. Some will even use the crossover to create the over-all system

curve using the crossover like an equalizer. For the rest of us, an accurately set crossover with a flat

response is the best way to start and using a RTA is the best way to get there.

Using the RTA to Set DELAY Time.

In the real world, no single or multiple speaker system is perfect. If there were such a perfect system, it

would more than likely be comprised of a single transducer that alone could faithfully reproduce the entire

frequency spectrum. Because no such system exists we have to deal with the problems associated with

multiple transducers. The first problem that you will encounter, whether you know it or not, is time travel.

That’s when the S• 3-way’s delay circuit becomes especially useful.

Ideally, the sound reproduced by each driver in the loudspeaker system would be traveling through the

air ultimately reaching the listeners at the same time. To accomplish this in a system using multiple dri-

vers or enclosures, the voice coils of all the drivers would have to be lined up on the same vertical axis.

This is very difficult to achieve in many cases because of the physical size of the different components,

and the position of the drivers in their enclosures. It is not uncommon to have a physical distance of 2” to

24" or more between the low and high frequency drivers. For example, front loaded low frequency dri-

vers and compression drivers mounted on a large horn. With no correction, the low frequency signal can

be traveling through the air 2" to 24" in front of the high frequencies and thereby reaching the listeners at

different times. Although the delay time between the low and high frequency signal may be relatively

small, the negative effects can be substantial. The problem is that both drivers are reproducing frequen-

cies at and around the crossover point, which arrive at the listeners at different times. Typically, the

resulting problem is comb filtering or cancellations at the crossover frequencies.

The S• 3-way features a DELAY control allowing you to dial up-to 2 milliseconds of delay. By using a

RTA and the S•3-way’s DELAY you can time align the drivers in your system and minimize the possibili-

ties of comb filtering. Now follow these steps, separately, for both the left and rights sides of your loud-

speaker:

• Set the crossover to the desired frequencies and press all the Mute switches to the ON position,

turning all of the S •3-ways outputs off. Position your measurement microphone approximately

15 feet from your loudspeaker array, halfway between the low and high frequency drivers. Now

turn all the GAIN controls to the fully counter clockwise position.

• Play a sign wave tuned to the crossover frequency, or connect a pink noise generator to your

loudspeaker system either from your mixer or in the S •3-way’s input. Now turn off the Low

Frequency Mute switch and adjust the S• 3-way’s INPUT GAIN to "0”. Adjust the LOW GAIN

control so that the signal is playing at a loud, but not too painful level. Make sure you only hear

sound from the low frequency driver.

• Adjust the level control of the RTA until it reads OdB at the crossover frequency. Now press the

LOW MUTE switch turning off the low frequency output.

16

ENGLISH

SETTING UP THE S•3-way USING A REAL TIME ANALYZER

• Turn off the High Frequency MUTE switch and turn up the High Frequency Level control until the

RTA reads 0dB at the crossover frequency.

• Now, press the LOW MUTE switch again turning on the low frequency output. Notice the reading

on the RTA at the crossover frequency. If the reading is 0dB, there is no need to adjust the delay

time and you can assume that the speakers are in phase. If the RTA reads less than +3dB you’ll

need to delay the low frequency.

• While watching the RTA display, slowly turn the DELAY control counter-clockwise until the dis-

play reads +3dB.

Setting the GAIN Controls Using a RTA

It is critical to set the GAIN output controls so that all the frequency bands combine to create an over-all

flat system response. Using a RTA to set the GAIN control will make it much easier for you to accomplish

a flat system response. Follow the steps below, separately for each side of your system, to set the GAIN

controls using a RTA.

• With the crossover set to the desired frequencies, press all the Mute switches to the ON position,

turning all of the S•3-way’s outputs off. Position your measurement microphone approximately

15 feet from your loudspeaker array at a level ranging from your chest to your ear. Now turn all

the GAIN controls to the fully counter clockwise position.

• Play a sign wave tuned to the crossover frequency, or connect the signal from a pink noise gen-

erator to your loudspeaker system, either from your mixer or directly in the S•3-way’s input. Now

turn off the Low Frequency Mute switch and adjust the S•3-way’s INPUT GAIN to "0’.

• Adjust the LOW GAIN control until the RTA has an average reading of OdB at and below the fre-

quency of the LOW crossover point.

• Turn off the Mid Frequency Mute switch and turn up the MID Frequency GAIN control until the

RTA reads the same average level in the MID band.

• Adjust the HIGH GAIN control until the RTA has an average reading of OdB at and above the fre-

quency of the HIGH crossover point.

At this point all of the frequency bands will be at the same level and your system will have a flat response.

After setting the levels you can use a graphic equalizer, like the Samson E62I, if you want set a particular

response curve to tune the speaker system for a specific sound.
