EMI
To reduce the possibility of outside electrical interference during performance, operate your amplifier and instrument
away from appliances/equipment that generate high levels of electronic/electromagnetic noise. This may include, but
is not limited to: fluorescent lighting, refrigerators, motors, mobile phones, radios, computers etc.
BEFORE USING YOUR AMPLIFIER
Speakers
Always ensure the correct speaker load (Ω) is connected to the SPEAKER OUTPUT terminal(s) at all times during
operation. The speaker outputs are found on the rear of the amplifier. The minimum total load is 8Ω. Only connect
cabinets as described below.
1 x 16Ω cabinet – Use the 16Ω speaker jack socket (Rear of chassis)
2 x 16Ω cabinets – Use both of the 8Ω speaker jack sockets (Rear of chassis)
1 x 8Ω cabinet – Use either of the 8Ω speaker jack sockets (Rear of chassis)
Note:
Never use instrument cable to make speaker connections.
Use only quality, unshielded speaker cable.
Speaker cabinets must have power handling at least equal to the amplifier’s rated output power.
Never use two cabinets of mismatched impedance (Ω).
Valves
To prolong the lifespan of the valves installed in the amplifier, when powering up, set the PLAY
selector switch to the up position for approximately 2 minutes. This places the amp in STBY
mode (Startup Tension Bypass, historically known as ‘standby mode). This allows the valves to
reach the correct temperature. After 2 minutes, switch to the PLAY position.
