Expanding an IZA system with a ZA amplifier

Expansion overview

The FreeSpace

zone amplifier makes system expansion easy. When a system design requires more loudspeakers than

the FreeSpace IZA 2120-LZ/HZ integrated zone amplifier can support, a FreeSpace zone amplifier can be connected to

provide additional power or zones.

When connected together, the IZA 2120-LZ/HZ and any zone amplifier (ZA 2120-LZ/HZ, ZA 250-LZ, ZA 190-HZ) can

operate together as one system, sharing the same music and paging sources. The IZA 2120-LZ/HZ amplifier operates

as the master of the zone amplifier, determining which audio sources will be heard. The overall MASTER LEVEL volume

can be controlled by the integrated zone amplifier in one larger zone, or volume control can be distributed in multi-zone

installations.

Using the included RCA cable, connect the AUX OUT of the IZA 2120-LZ/HZ amplifier to the unbalanced INPUT of any

zone amplifier.

Note: It is recommended that when amplifiers are connected together, that both amplifier AC power cords are plugged

into the same AC outlet to reduce potential noise issues.

When using a front-end signal processor, or connecting multiple zone amplifiers to an integrated zone amplifier, the in-

cluded RCA cable may need to be modified. The wiring diagram for the zone amplifier line-level input RCA connectors is

provided below.
