INPUT SECTION: There are two parallel input connectors (one female
XLR and one 1/4" jack) per channel. Either can be used as an input or as a
link to chain amplifiers.

as well as an unbalanced line. The unbalanced line uses a standard tip-
sleeve connection. The tip is positive and the sleeve is negative/ground.
The balanced line uses a tip-ring-sleeve connection. Tip = hot or positive
(+), ring = cold or negative (-), and sleeve = shield/ground.

ume level of the subwoofer is controlled automatically to match the vol-
ume levels of the satellite speakers. It will always maintain a perfect balance
to give you incredible sound quality!

lift the balanced input connectors' ground/shield from the amplifier's
ground. When the signal ground lifted, the sound source disconnects from
the amplifier's ground preventing ground loops which can generate hum
and noise. See the Signal Ground Lift Switch Instructions for more detail.
OUTPUT SECTION: Disconnect unit from the AC power source before
making any connections.

connectors that will accept cables with Speakon™ connectors. The sub-
woofer is already connected internally, so you don't have to worry about
connecting it to the amplifier.

OPERATION:
1. S O : The unit has two channels for stereo operation. Each

channel provides a separate signal at the speaker outputs. The following
instructions are for use with 8 ohm speakers of matched power ratings. We
suggest only using the speakers that come with the unit.

of your input as high as you think you'll need it. This way it will be as high-

sound with the least amount of noise. Now play some music and listen for

Now lift the ground by moving the S
to the right. Turn the power back ON and listen to determine which posi-
tion makes the overall sound quieter with the least amount of noise and

CAUTION: DO NOT DISCONNECT THE AC GROUND ON THE POWER
AMPLIFIER IN ANY WAY. THIS CAN BE VERY HAZARDOUS!!
SETUP:
There are various ways to set up this system:
BASIC SETUP:
This is your basic setup, perfect for small parties and venues. The ideal
location for your subwoofer is close to a wall or in a corner. This will give
you the fullest bass response. Your 2 satellite speakers can be placed up on
stands on each side (stands must be purchased separately).
T WO-SYSTEM SETUP:
This setup is perfect for larger venues. This setup requires 2 XTR-500 sys-
tems. This will give you a total of 800 watts RMS! Place a subwoofer on
each side to the left and right. Using the high-hat hardware and connecting
pole (which can be purchased separately), place the pole in the high-hat
socket on the subwoofer, and a satellite speaker on top of the pole. The 2
remaining satellite speakers may be used as either floor monitors, or
placed on stands elsewhere in the room giving you a louder and fuller
using the

sound. Each speaker system in this setup must be used in MONO mode
(2).
(see Mono section). Connect the system that is on the left side of the audi-
ence to the LEFT channel of your mixer, and the system that is on the right
