PRODUCT FEATURES

Front Panel

Power Switch

The power switch turns the ampliﬁer on and o.

When the power switch is lit solid white, the ampliﬁer

has power, is turned ON and ready to operate.

When the power switch is slightly dimmed the

ampliﬁer is in standby mode.

When the power switch is blinking white, the ampliﬁer

power supply is in thermal protection. The channel LEDs

will also light red when the power supply is in thermal

protect mode.

NOTE: Upon initial power up there will be an

approximately 9-12 second boot up cycle. This is

normal.

Input/Output Lights

When each channel is active, the LED will light green as

long as a signal is present.

When the LED blinks red, this is an indication that the

channel is being overdriven.

When the LED lights are solid red this is an indication

the ampliﬁer is in protect mode. While in protect mode

the LED lights will periodically light green to retest the

output to determine if the short has been removed.

Protect mode could be caused by a short in the wire,

overheating of the ampliﬁer or possibly an internal

problem with the ampliﬁer.

NOTE: WHEN ANY OF THE LEDS ARE LIT RED TURN

THE AMPLIFIER OFF IMMEDIATELY. DETERMINE THE

CAUSE OF THE PROBLEM BEFORE TURNING THE

AMPLIFIER ON.

Volume Level Control

Each channel on the ampliﬁer has front panel recessed

volume controls that will adjust the output and turn

on volume. The ampliﬁer must be powered on to make

these adjustments.

Rear Panel

Inputs

The SR 2-125 ampliﬁer has analog, coax and toslink LINE

INPUTS

and loop OUTPUTS.

The analog loop outputs are non buered. The

maximum number of ampliﬁers that can be looped

together will depend on the output capability of your

source component. The digital outputs are buered

and can support multiple ampliﬁers. Only one output

can be used at a time.

Speaker Connections

The removable block connectors used on the SR 2-125

ampliﬁers will accept up to 12 gauge wire.

Volume Level Control

Volume can be controlled from the

individual recessed volume level

control screws, located on the front

panel (see Figure 11). These volume

controls balance the desired sound

levels per channel.

The volume level controls are set to

maximum, fully clockwise, by default.

For the best sound you should

use premium speaker wire

that complies with fire rating

codes. Be sure to check

local codes governing wire

that may be installed within

walls or ceilings. SONANCE

ampliﬁers are stable with any

reputable brand of speaker

wire or cable. The SR 2-125

ampliﬁers use speaker

block connectors that can

accommodate up to 12 gauge

wire (see Figure 9).

NOTE: ALWAYS CHECK LOCAL BUILDING CODES BEFORE

INSTALLING WIRE IN WALLS OR CEILINGS.

IMPORTANT: USE CAUTION WHEN SETTING VOLUME

LEVELS EITHER ON THE AMPLIFIER OR AN AUDIO SOURCE

AS NOT TO OVERDRIVE AND POSSIBLY DAMAGE SPEAKERS.

VERIFY ALL SOURCES AS OUTPUT VOLTAGE VARIES FROM

DEVICE TO DEVICE.

Source Connections SR 2-125

On the left side of the rear panel are the audio inputs for

the left and right channels. In addition to the left and right

inputs there are also loop outputs for each channel.

The analog loop outputs are non buered. The maximum

number of ampliﬁers that can be looped together

will depend on the output capability of your source

component. The digital outputs are buered and can

support multiple ampliﬁers. The source connected to the

LEFT and RIGHT LINE IN Inputs pass through the

LEFT and RIGHT LINE Outputs (see Figure 10). This also

applies to the Coax and Toslink inputs.

FIGURE 10: SR 2-125 LEFT, RIGHT LINE INPUTS/OUTPUTS

Protection Circuitry and LEDs

The SR 2-125 ampliﬁers have a multi-stage protection

system to prevent damage to your ampliﬁer and speakers.

SR 2-125 Ampliﬁer Channel Protection

If a channel encounters a short-circuit or an extremely low

impedance this will cause the aected channel outputs to

automatically mute. The output of the aected channel

will remain muted until the fault has been corrected. Only

the aected channels output will mute, all other channels

will continue to operate normally.

SR 2-125 Ampliﬁer Channel Protection Indication

On the front panel of the SR 2-125 ampliﬁers are dual color

LEDs that illuminate to indicate the current operating

status of each ampliﬁer channel.

When the LED blinks red this is an indication that the

channel is being overdriven.

When the LED lights are solid red this is an indication the

ampliﬁer is in protect mode. While in protect mode the

LED lights will periodically light green to retest the output

to determine if the short has been removed. Protect mode

could be caused by a short in the wire, overheating of

the ampliﬁer or possibly an internal problem with the

ampliﬁer.

IMPORTANT: ALLOWING THE AMPLIFIER TO OPERATE

WITH ONE OR MORE CHANNELS IN PROTECT MODE

FOR AN EXTENDED PERIOD OF TIME CAN DAMAGE THE

AMPLIFIER.

SR 2-125 Ampliﬁer Power Supply Protection

The ampliﬁer also has protection for the power supply.

If the power supply heat sink temperature exceeds the

design maximum the protection circuit will activate

disconnecting all channel outputs. This is indicated by a

blinking light on the front panel power switch.

IMPORTANT: ANY TIME THE PROTECTION CIRCUITS ARE

TRIGGERED, UNPLUG THE AMPLIFIER’S POWER CORD

FROM THE WALL OUTLET BEFORE TROUBLESHOOTING.

Rack Ear Installation SR 2-125

The SR 2-125 ampliﬁer ships with two long rack ears for
