fier input signal. Switch the breaker to the ‘ON’ position. Then power the unit up normally.
IEC-320 C14 POWER INLET
Accepts power cords with IEC-320 C13 connectors. Use only approved power cords.
EXTERNAL TURN-ON SELECTOR (EXTERNAL/LOCAL)
LOCAL operation
: To operate only via the front panel push-button power
switch, place the External Turn On selector in the LOCAL position. If a control
voltage is present at the ‘IN’ terminals it will still be available at the ‘OUT’ termi-
nals after the power-up sequence.
EXTERNAL (Remote) operation:
To enable remote power ON/OFF control of
the amplifier this switch must be in the EXTERNAL position.
Supply a 4v to 12v
A/C or DC control voltage to the ‘IN’ terminals of connector
. Use paired wire
of 22 to 18 gage sufficient in length between the source device and the SST
amplifier. Set Selector switch
to “
External
”. The amplifier will now power-up
only when the control voltage is present (on). Immediately following power up,
the control voltage will appear at the ’OUT’ terminals of connector
for the
control of other equipment. The removal of the control voltage (0v) causes the
amplifier to turn ‘off’ and the control voltage at the ‘OUT’ terminals is interrupted.
REMOTE POWER ON/OFF CONTROL CONNECTOR
To power-up the 7B
SST2
amplifier using an external control voltage, connect 4
to 12 volts, AC or DC, to the IN pins of this connector with the External/Local
switch
set to EXTERNAL. When this control voltage is removed the ampli-
fier turns off. Use stranded wire between 22 and 18 AWG, with 1/4" of the
insulation stripped off, to connect the control voltage to the interface connec-
tor shown at the right. Do not over tighten the wire-clamps; .5Nm or 4.5Lb-in is the maximum torque recommended.
Then plug the interface connector into the EXTERNAL TURN ON connector.
