Master Trigger Input
The master trigger input (leftmost 3.5mm socket) is used to take the 350 in and
out of standby. The master trigger input is designed to accept a 3.5mm diameter
male plug. The voltage rating is +5V to +12V DC level ON and 0V DC level
OFF.
The plug must follow the specifications as per the following diagram:
Slave Trigger Output
A parallel slave trigger output (rightmost 3.5mm socket) is provided to switch on
or off any connected peripherals to the 350. The slave trigger output is designed
to accept a 3.5mm diameter male plug. The voltage rating is +12V DC level ON
and 0V DC level OFF.
The plug must follow the specifications as per the diagram below:
Power Switch
Set this switch right (I) to turn power ON. Mute relay circuitry is employed in
the 350 so output is muted momentarily after the power switch is actuated. Set
the switch left (O) to turn the unit off, at which time the outputs will be
disconnected.
Speaker Output Terminals
The 350 is equipped with two sets of output terminals per channel, to enable
easy hook-up for bi-wiring of loudspeakers or additional loudspeakers. All
terminals are clearly marked and colour coded RED Positive (+) and BLACK
Negative (-). This polarity must be observed when connecting loudspeakers, i.e.
positive terminal of the 350 to the positive terminal of the loudspeaker and
negative terminal of the 350 to the negative terminal of the loudspeaker.
Caution! Never connect the amplifier’s output terminals to any device other than a
loudspeaker.
Please do not short circuit the amplifier’s output terminals.
Never connect the output of one amplifier to the output terminals of
another amplifier.
Do not over-tighten the binding posts on your amplifier.
