CONTROLS:
MASTER: (Continued) -rectly to a mixing board or recorder, this control will determine the amount of signal you will be sending via this jack. In this application it is usually best to start with the MASTER controls set to ( 7:00 ) and gradually increase them to the proper level. This minimizes the possibility of blowing speakers or eardrums in the event the engineer has an extremely sensitive input headroom setting in place at the console.
CH.1 / CH.2 / CONTOUR SELECT SWITCH:
Use this mini-toggle to select one of the three Modes - CHANNEL 1, CHANNEL 2 or CONTOUR. In order for the channel select Footswitch to operate when connected to your new F-Seriesamplifier, the channel select mini-toggle switch must be in its middle position - FT . SW.

ON / STANDBY:
Perfect for set breaks...this toggle switch also serves an even more important purpose. In the STANDBY position (switch up), the tubes are at idle so that during power up they may warm up before being put to use.
Before the power is switched on, make sure the STANDBY switch is in the STANDBY position. Wait at least 30 seconds and then flip the STANDBY switch to its ON position. Following this simple warm up procedure helps in preventing tube problems and increase their toneful life substantially.
