Outputs
Connect the loudspeakers to the screw terminals on the rear panel.
Low Impedance
Connect low-impedance speakers between the 4 or 8Ω terminal and the COM terminal. DO NOT
connect a combined impedance lower than 4 Ω. Make no connections to the 100V terminal.
The following combinations MAY be connected
1 × 16 Ω
16 Ω
2 × 16 Ω
8 Ω
3 × 16 Ω
5.3 Ω
4 × 16 Ω

2 Ω
High Impedance 100V / 70V
Connect 100 V line speakers between the 100V terminal and the COM terminal or Connect 70V line
speakers between the 70V terminal and the COM terminal
ADD UP the total of the stated powers on each loudspeaker, or, if the speakers are fitted with
selector switches, add the selected power. The total power of all the connected speakers MUST BE
LESS THAN 60 W. DO NOT connect low impedance speakers to the 100V or 70V terminals, Make no
connection to the 4-8-16 Ω
Operation
ALWAYS turn the MASTER volume controls to zero before switching on; do not touch the speaker
outputs whilst the amplifier is running as this could result in electric shock.
Set the MASTER level control to about 75% of full clockwise rotation.
Then adjust the microphone level controls MIC1, MIC2, to achieve the desired volume
Adjust the line level control for a comfortable background music level
Adjust the treble and bass controls for the greatest clarity when using the microphone.
Note that the MUTE facility only operates on microphones connected to the MIC1 input.
Mute Control (Priority)
When the terminals are a short circuit it will mute MIC2, AUX & PHONO inputs and MIC 1 is then
priority (this can be used in conjunction with a fire alarm trigger for announcements)
