Russound A-SZ4 Installation Manual

Introduction

The A-SZ4 is an optional ABUS subzone chassis for C-Series audio systems
which adds subzones for audio distribution in lower priority areas of a home.
For instance, an en-suite bathroom could be a subzone to the master bedroom.
Subzones share the same audio source selection with the main (host) zone
though they each have independent control for power and volume level in
their respective locations.

The industrial design of the A-SZ4 perfectly complements the C-Series
multiroom audio system controllers and shares the same half rack width
form factor as the ST1 Tuner and D-250 ampli er. As such, these products
can be mounted side by side in a variety of con gurations to meet system
requirements.

Up to two A-SZ4 units may be used with a single C-Series controller for a total
of eight subzones. Each subzone can be individually assigned to a speci c host
zone on the C-Series controller so multiple subzones (up to 8) can be paired
with a single host zone. It uses A-BUS keypads (can be A-K3, A-K5L, A-K5L with
A-KSC) for both the control and ampli cation of subzone audio. Speakers in
these rooms connect directly to the A-BUS keypads with standard speaker
cable.

Like Russound’s C-Series multiroom audio controllers, the A-SZ4 features
an internal dual-voltage power supply for 110-240V operation and an IEC
terminated detachable power cord for world-wide compatibility.
