1. POWER SWITCH
Press this switch to the right to apply power to the unit. (The orange power
LED
②
will illuminate to show when the amplifier is powered.)
2. POWER INDICATOR
An orange LED unmistakably tells when the amplifier is turned on. (Front panel LED
indicators are different colors so the operator can see the status of the amplifier from
across the room with only a glance.)
3. CHANNEL 1 LEVEL CONTROL
A precision 41 step input level attenuator is used to adjust volume levels.
4. CHANNEL 1 SIGNAL & CLIP INDICATORS
The green LED comes on when signal is present on channel 1 and the red
LED comes on when channel 1 has reached its maximum output capability.
5. CHANNEL 2 LEVEL CONTROL
A precision 41 step input level attenuator is used to adjust volume levels.
6. CHANNEL 2 SIGNAL & CLIP INDICATORS
The green LED comes on when signal is present on channel 2 and the red LED
comes on when channel 2 has reached its maximum output capability.
7. EQ EXPAND SWITCH
This switch, when set to its ‘in’ position will boost the highs and lows by +4dB at 80Hz
and 12kHz. When set to the ‘out’ position it provides a flat output response.
8. COOLING VENTS
Convection cooling silently passes air from front to rear. Allow adequate ventilation!
Never block the vents or attach a front cover to the rack while the equipment is operating.
9. CHANNEL 1 1/4” PHONE JACK INPUT
This stereo phone jack is designed to receive either balanced or unbalanced input sig-
nals. Balanced signals coming into this jack should be wired with the connector’s tip going
to and the connector’s ring to signal -. The connector’s sleeve is then tied inter-
nally to ground.
10. CHANNEL 1 XLR INPUT CONNECTOR
Like the 1/4” phone jack, this input connector will accept either balanced or unbalanced
signals. Pin 2 is , pin 3 signal - and pin 1 is grounded.
11. CHANNEL 2 1/4” PHONE JACK INPUT
Performs the same function as channel 1’s 1/4” input. (See 9.)
12. CHANNEL 2 XLR INPUT CONNECTOR
Performs the same function as channel 1’s XLR input. (See 10.)
13. BRIDGE SWITCH
Press this switch ‘in’ to use the BRIDGE MONO feature. ‘Out’ for STEREO operation.
14. CHANNEL 1 1/4” PHONE JACK SPEAKER OUTPUT
Standard 1/4” phone jacks are supplied for convenient speaker connection.
15. CHANNEL 1 BINDING POST SPEAKER OUTPUT
An alternative for connecting speakers is through the binding posts. RED is positive and
BLACK is negative. These high current connectors will safely clamp bare wires at their
base or will accept standard single or dual banana plugs. (The two RED binding posts are
used for mono bridging, ch1 is + and ch2 is -).
16. CHANNEL 2 1/4” PHONE JACK SPEAKER OUTPUT
Performs the same function as channel 1’s jack. (See 14.)
17. CHANNEL 2 BINDING POST SPEAKER OUTPUT
Performs the same function as channel 1’s binding posts. (See 15.)
18. AC POWER CORD
Always use grounded (3 prong) outlets. Defeating the power cord’s ground connection
can result in electrocution.
19. MAIN POWER FUSE
Should the fuse ever blow, replace only with same type and value:
3AG 2A, Slow Blow for 120VAC units.
3AG 1A, Slow Blow for 230VAC units.
