7. Input Amp Configuration Switches
These DIP switches have a number of different functions.
CH1 MicOn/LineOff
CH1 Normal
CH1 Priority
CH1 VOX
CH1 to Zone 2
CH2 to Zone 2
Phantom Power
8. Input 1 Terminal
This is a 5-pin Phoenix-type connection with 3 pins for
balanced input signals and 2 connectors for priority
push-to-talk button connection� The input accepts direct
connection of line or microphone inputs as selected by the
mic/line DIP switch (point 7).
9. Input 1 VOX Threshold Control
This control adjusts the level at which the Input 1 signal
should be before other signals are muted� This only works
when the CH1 VOX DIP switch is turned on�

When set to Off, it allows line-
level signal input through channel
1� When set to On, it allows
microphone-level signals through
channel 1�
This switch sets channel 1 to
normal, with no priorities�
Enables muting of channels when
priority circuit on input 1 is closed�
Connect the priority connection on
Input 1 to microphone's push-to-talk
function when this is activated�
Activating this switch allows
automatic muting when channel 1
input passes the preset threshold
(point 8).
Activating this switch sends the
channel 1 input signal to the zone 2
output channel�
Activating this switch sends the
channel 2 input signal to the zone
2 output�
This switch activates phantom
power to the Input 1 input� Phantom
power is required for use with
condenser microphones�

10. RCA Inputs
These inputs accept stereo unbalanced line-level RCA
input signals� The input signals received through these
connectors are summed�
11. Zone 2 / MOH Output and Control
This 4-pin Phoenix-type connector provides two different
output possibilities� The 8 ohm side is for 1W output to
external speakers, while the 600 ohm connectors are for
connecting private branch exchange (PBX) telephone
systems for on-hold music� For further info on wiring, see
the Output Wiring section�
12. Preamp Output Terminal
This balanced 3-pin Phoenix type connection sends the
GA335 and GA460 mixer/amplifier's signal to external
devices� The output signal level is dependent on the
master level control� For further info on wiring, see the
Output Wiring section�
13. Amplifier Output
Speakers can be connected to this output terminal�
Connections available include COM (common), 70V,
100V and 8 ohms� These input connections can accept
terminal forks up to 10 AWG� For further info on wiring,
see the Output Wiring section�
14. Power Socket
This is for a standard IEC power cable� Please connect
the cable to a suitable AC power outlet� While the GA
series offers a universal power supply, be sure to check
local voltage levels before connecting the unit to ensure
they correspond�
