INSTRUCTIONS FOR CONNECTING RUSSOUND EZ-BLOCK
The EZ-BLOCKS ar
e designed for surface mount
applications. P
osition the EZ-BLOCK in an ar
ea
close to the amplifier and volume contr
o
l
wiring. Secur
e to the mounting surface with
four #8 x 1/2” scr
ews.
An EZB-2SC allows for the connection of an
additional 4 volume contr
ols. T
o
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 sur
e the two connector
s line up pr
operly;
ther
e should not be any pins extending beyond
the end of the female connector
. With the two
connector
s pr
operly lined up, firmly pr
ess the
two units together
. Up to thr
ee EZB-2SC
sections can be added onto the original EZB-
1SC unit, allowing for a total of 16 impedance-
matching volume contr
ols.

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 pr
ovides par
allel
distribution for the audio signal fr
om a single
amplifier to be r
outed to multiple volume con-
tr
ols which have been wir
ed in a “home run”
configur
ation. The primary unit of the EZ-
BLOCK (EZB-1SC) pr
ovides a single 4-conductor
amplifier input and four speaker pair outputs.
Each successive section (EZB-2SC) plugs into the
pr
evious section and pr
ovides 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 contr
ols to a 4-ohm stable amplifier in a
neat, or
ganized arr
angement.

The EZ-BLOCK has r
emovable modular connec-
tor
s that pr
ovide color-coded wir
e termination
without the need for set-scr
ews. Strip about
3/8” of insulation fr
om the ends of all wir
es to
be connected. If necessary
, twist the exposed
conductor to insur
e that no loose str
ands exist.
Remove the AMP INPUT connector by pulling
up away fr
om the boar
d on the connector
. Lift
wir
e locking lever on connector
. Insert the wir
es
fr
om the amplifier speaker level output, being
car
eful to observe pr
oper polarity
, and lower the
lever with a “snap.” In the same way
, connect
each volume contr
ol to the appr
opriate
SPEAKER connector
. Each pair of speaker
s will
then connect to the impedance-matching vol-
ume contr
ol.
