GRAPHIC EQ: (Continued)
EQ back out of the circuit, the straight tone sounds to flat. Don’t worry! It’s just “hearing hangover”. All the MARK IV’s modes were developed without using the EQ so that it could be an accessory - not a necessity.
OUTPUT LEVEL:
This control adjusts the playing loudness of all three modes equally. Once you’ve got the sounds set up as you would like them, using this one control will allow you to work louder or softer venues. Notice that the OUTPUT LEVEL control also functions as an Effects Return control, owing to its location in the signal chain.

SILENT RECORDING: (Pull Switch)
This push/pull switch turns off the signal at the output stage therefore muting the speaker. This enables you to record silently (using the RECORDING out jack, not the SLAVE D.I.) without the need to disconnect the speaker.

NOTE: Remember...a load must be maintained on the amplifier to avoid damage to the transformer. A soak resistor (8 ohms) can be purchased for just such purposes. See your local dealer or give us a call and we’ll assist you if need be.
STANDBY:
The STANDBY switch turns off the high voltages inside the amplifier while allowing the tube filaments to stay warm and ready for immediate use. It’s a good practice to turn on the A.C. power with this switch in the
EQSTANDBY position, allowing the tubes 30 seconds or so to warm up. This procedure
ON
prevents tube problems and increases their toneful life substantially.

POWER: (Full & Tweed Power)
This switch has three positions: FULL POWER, OFF and TWEED POWER. The OFF position is in the center and is unlabeled. Use FULL POWER for maximum volume and clean headroom. TWEED POWER works like a
