MODEL 263A

CONNECTING THE 263A TO YOUR SYSTEM

The 263A can be used with any line-level device. Some common examples include mixing consoles,

electronic musical instruments, patch bays, and signal processors.

For all connections, refer to the following steps:

1. Turn Off all equipment before making any connections.

2. Mount the 263A in a 1U rack space (optional).

Note: Avoid over-tightening of rackmounting screws as this could damage the front panel.

The 263A requires one rack space (height) and 1/2 rack space (width). It can be mounted above or below

anything that doesnÕt generate excessive heat, since it requires no special ventilation. Ambient tempera-

tures should not exceed 113¼F (45¼C) when equipment is powered. Hardware for mounting your 263A is

provided in the optional accessory kit.

Make connections via 1/4Ó phone jacks according to your requirements.

To save rack space, two 263A units may be mounted side-by-side. In addition, the 263A can be mounted

next to other dbx Òhalf-rackÓ units: 760X Mic Preamplifier, 1024 Buffer Amplifier, 140X Type II Noise,

163A Compressor/Limiter, 363X Dual Noise Gate, 463X OverEasy Noise Gate, or 563X Hiss Reducer.

Hardware for side-by-side mounting is included in the optional accessory kit. If the rubber feet were used

for table top operation, they should be removed at this time.

Caution: Never remove the cover. There are no user-serviceable parts inside, and you run the risk of an

electric shock.

Connect the AC plug (shipped with the unit) to the 263AÕs rear panel POWER jack.

Note: Check the line voltage (printed on the rear panel) and verify that it is correct.
