EZB Connecting Blocks
The EZB-1 and EZB-2 connecting blocks are Russound accessories that simplify con-
nections of multiple volume controls and speaker pairs. The EZB-1 is a neat, compact
wiring device capable of connecting four volume controls to an amplifier's outputs.
The EZB-2 expands the EZB-1 to another four volume controls. Multiple EZB-2's can
be used to expand the system to sixteen volume controls (using a 4-ohm amp and
8-ohm speakers).
Wiring Instructions
(Refer to Figure 3 on page 6)
1.
Connect the leads from the amplifier’s outputs to the connector labeled input.
The wires should stay consistent, left + of the amplifier to left + input of the
volume control, observing polarity and identification.
CAUTION: Do not reverse the input and output connections!!
CAUTION:
A majority of receivers are designed to operate at a rating of
8 ohms. On receivers that offer A and B speaker outputs, both A and B
connections share the same amplifier. It is important to note, due to the way
many receivers are wired, that when using impedance matching devices, such
as UltraMatch™ volume controls, it is recommended to wire only to the A
output. If you have any questions contact Russound directly.
2.
As outlined in step #1, connect the speaker wires to the connector labeled
output.
3.
Install the completed assembly in an 18-ci single-gang junction box. Insert
carefully to avoid excessive strain on the connector. Taking the time to feed the
excess wire out the back of the junction box will help you with the final
assembly.
