INSTRUCTIONS FOR CONNECTING RUSSOUND EZ-BLOCK

The EZ-BLOCKS are designed for surface mount

applications. Position the EZ-BLOCK in an area

close to the amplifier and volume control

wiring. Secure to the mounting surface with

four #8 x 1/2” screws.

An EZB-2SC allows for the connection of an

additional 4 volume controls. To connect the

EZB-2SC to the existing EZB-1SC, line up the

male pin header on the end of the EZB-2SC

with the female pin socket of the EZB-1SC.

Make sure the two connectors line up properly;

there should not be any pins extending beyond

the end of the female connector. With the two

connectors properly lined up, firmly press the

two units together. Up to three EZB-2SC

sections can be added onto the original EZB-

1SC unit, allowing for a total of 16 impedance-

matching volume controls.

MOUNTING

DESCRIPTION

NOTE: This unit in and of itself provides no impedance

matching. It is designed to be used in systems utilizing

impedance -matching volume controls.

The EZ-BLOCK Modular Block provides parallel

distribution for the audio signal from a single

amplifier to be routed to multiple volume con-

trols which have been wired in a “home run”

configuration. The primary unit of the EZ-

BLOCK (EZB-1SC) provides a single 4-conductor

amplifier input and four speaker pair outputs.

Each successive section (EZB-2SC) plugs into the

previous section and provides an additional four

speaker pair outputs. By adding additional EZB-

2SC units, the EZ-BLOCK can be used for easily

connecting up to 16 impedance-matching vol-

ume controls to a 4-ohm stable amplifier in a

neat, organized arrangement.

The EZ-BLOCK has removable modular connec-

tors that provide color-coded wire termination

without the need for set-screws. Strip about

3/8” of insulation from the ends of all wires to

be connected. If necessary, twist the exposed

conductor to insure that no loose strands exist.

Remove the AMP INPUT connector by pulling

up away from the board on the connector. Lift

wire locking lever on connector. Insert the wires

from the amplifier speaker level output, being

careful to observe proper polarity, and lower the

lever with a “snap.” In the same way, connect

each volume control to the appropriate

SPEAKER connector. Each pair of speakers will

then connect to the impedance-matching vol-

ume control.
