Intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. Intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product.

Both the XR 684 and the XR 684+ are covered in this guide. The two units share the same preamp functions. They are different only in the power amp as noted below. Throughout this manual, the term “XR 684” will refer to both units unless otherwise noted.

CHANNEL SECTION: CHANNELS 1-4 1. MIC INPUT: XLR balanced, low-impedance channel input optimized for a microphone or other low-level source. Pin 2 is the positive input. Because of the wide range of gain adjustment, signal levels as high as +10 dBV (2.45 V RMS) can be accommodated.

Input is adjusted by the Level control (#4). The signal is then routed to the internal power amp. If the XR 684 is in Left/Right mode then the signal will go to the Right Speaker Output (#37). In Mon/Main mode the signal is combined with the Left and placed on the Main Speaker Output.

It is recessed to prevent accidental switching during a performance. Use a non-metallic object to change the switch position (e.g., a toothpick). The XR 684 is shipped from the factory in the default setting of Left Main to the upper EQ and Right to the lower EQ. When this switch is depressed it switches the lower EQ to (mono) PA Left + Right.

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.

CAUTION: When using the bridge output no other speakers should be connected to the adjacent parallel speaker outputs. In addition, the minimum load for the XR 684 in bridge mode is 8 ohms. Do not allow the total impedance to drop below 8 ohms or serious damage to the amplifier may occur.
** Min input level (sensitivity) is the smallest signal that will produce nominal output (2 dBu) with channel and master level controls set for maximum gain. * Nominal settings are defined as all controls set a 0 dB (or 50% rotation for rotary pots) XR 684 Output Specifications: Function Minimum Load Z...
