Source Components

The ZR-4 MultiZone Receiver has RCA audio inputs for connecting three external source components. In addition to the built-in AM/FM tuner, these three source components can be selected to play in any of the four zones. With this configuration, a user in one zone can listen to a source component while another user in a different zone listens to a different source component (e.g. the CD can be selected in Zone 1 while the AM/FM tuner is selected in Zone 2). Additionally, each of the four zones can be set to an individual volume level. If more than one zone chooses the same source component, control of that source component is shared between the zones.

Keypads

Keypads with built-in IR sensors plus a Hand-Held Remote Control enable the user to control the Niles ZR-4 MultiZone Receiver and its connected source components. The built-in AM/FM tuner is controlled directly from the Keypad. The input for the connected source components is also controlled by the Keypad, but all source component functions are controlled using the Hand-Held Remote Control. The Keypads connect to the ZR-4 MultiZone Receiver by a “home run” of CAT-5 cable terminated with RJ-45 connectors using the T568A wiring convention. (See Page 6).

MicroFlasher Outputs

The included Niles MicroFlashers® connect to the numbered flasher outputs on the rear panel of the Niles ZR-4 MultiZone Receiver. Niles MicroFlashers send IR commands to the individual source components for control. An optional Niles IRB-1 High-Output IR Flasher (FG01023) can be connected to the flasher port labeled High Output Flasher to control more than one source component at a time.

Global 12V Control Output

An optional Niles AC-3 Voltage-Triggered AC Power Strip (FG00242) can be connected to the 12V Control Output to automate source component turn-On and turn-Off, as well as an external power amplifier turn-On and turn-Off.

Loudspeakers

Each zone has “home run” speaker cables from the Niles ZR-4 MultiZone Receiver to the location of the speakers. Connections are made utilizing removable speaker terminals. These terminals accept speaker wire up to 16 AWG in size. The receiver’s high-quality digital amplification can accommodate one pair of 4 ohm speakers per zone or two pairs of 8 ohm speakers per zone without going into protection or shutting down.

AM/FM Antenna Connections

The included FM Dipole Antenna connects to the female 75 ohm coaxial connector and the AM Loop Antenna connects to the spring-loaded terminals labeled AM and GND. Antennas must be connected to both ZR-4s when using two ZR-4 MultiZone Receivers.
