Peavey 684, 684 Plus

26. MAIN LEVEL: This is the master level control for the main mix sent to the Left/Mono and Right output

jacks. This control sets the Main level going to the power amp when in Main/Monitor mode (see System

Mode #24). Agood starting position for this control is the center detent position (12:00).

27. PHANTOM POWER SWITCH: Applies 48 V DC voltage to all input XLR connectors to power micro-

phones that require it.

CAUTION! When phantom power is switched on, make sure that any channel you are plugging a mic into is

turned down in both the main and monitor mixes. Otherwise, there will be a loud pop in the PA. This is

normal. It is best to plug all mics into their respective channels with the phantom power switched off.

This reduces noise in the PAand reduces the chances of the mic being damaged. If phantom power is used,

do not connect unbalanced microphones or other devices that cannot handle this voltage to the XLR inputs.

(Some wireless receivers may be damaged; consult their manuals for compatibility.) The line input 1/4" jacks

are not connected to the phantom supply, and are safe for all inputs (balanced or unbalanced). An unbal-

anced-to-balanced impedance converter, such as the Peavey 5116 or a Peavey 1:1 Interface Adapter, can

also be used to isolate a mic from phantom voltage.

28. EFX DEFEAT: This 1/4" jack accepts an on/off 1/4" footswitch (Peavey Pt. #00051000) to defeat the

effects of both the Main and Monitor mixes.

29. MONITOR OUTPUT: This 1/4" jack provides an output from the monitor mix to supply external power

amp/monitor combinations. The level of this signal is determined by the Monitor Level control.
