FRONT PANEL CONTROLS IN DETAIL
Power Switch
The “Power” switch determines the operational readiness of the SA-600W and
should be the only method used to turn the amplifier on and off. Do not use a power
strip switch, switched outlet or any other external switch as these may result in
undesirable and potentially damaging transient pops. Do not unplug the SA-600W’s
AC power cord while the unit is turned on.
The Power switch has three positions:
“off ”: The SA-600W is powered down. In this state, a negligible current draw
will exist for operating the main power relays. The front panel LED is RED and
the LCD Display is dim with the message “In Standby. Power switch is OFF.”
displayed.
“on”: The SA-600W is fully powered at all times. The front panel LED is GREEN
and the Home Screen menu options are listed on the LCD Display.
“auto”: In this position, the SA-600W can be activated by the following methods:
Signal Sensing: In this default mode, the SA-600W will power up when an audio
signal is present at any of its inputs and will power down its internal amplifier
when no signal has been detected at its inputs for sixty (60) minutes. When
dormant, the SA-600W will draw a minimal amount of current (< 1 watt) to
power its Signal-Sensing circuitry. The front panel LED turns YELLOW when the
SA-600W powers down to indicate Standby mode and the LCD Display will show
“In Standby. Waiting for audio input.” The front panel LED will turn GREEN
when the SA-600W powers up.
Note: In the unlikely event that the auto Signal-Sensing feature is not sensitive
enough for a particular system, use a Y-adaptor cable (one female to two male
RCA-type connectors) to split the incoming signal into both RCA line inputs on
the SA-600W. This will increase the input sensitivity by 6 dB. Please be aware
that if there is significant noise entering the inputs, the SA-600W may not turn
off as desired. If this happens, remove the Y-adaptor cable and/or look for the
noise source in the upstream components.
12V Trigger: Optionally, the SA-600W can be activated using a 12V DC signal.
To enable this mode, select “SYSTEM” on the Home Screen screen (see page 18
for more info) and select “12V ON”. This setting overrides audio Signal-Sensing
and will only turn on the SA-600W when a 12V DC signal is present at its
“12V Trigger - In” connection. When the 12V DC signal is removed from
the “12V Trigger - In” connection, the SA-600W will enter Standby mode
immediately, the front panel LED turns YELLOW and “In standby. Waiting for
12V trigger.” will be shown on the LCD Display.
Note: Whenever the SA-600W is ON, its “12V Trigger - Out” output will be
active, regardless of the “SYSTEM” setting. This allows you to control multiple
SA-600Ws using a single 12V trigger lead by daisy-chaining them together (“12V
Trigger - Out” activates the “12V Trigger - In” of the next amp, etc.).
