Instruction Manual 5 4 3 2 RACK MOUNTING When assembling equipment in a rack, the DRZ35 should either be on the bottom of the rack or above any equipment that does not produce heat to ensure a source of cool air to the bottom of the unit. Provide at least 1 RU (Rack Unit) of space above and below the DRZ35 so that cool air is available to the unit.
Connections Connecting Speakers to the Zone Switch Bank The terminal strip in the Zone Output section of the rear panel allows groups of speakers to be connected to a selector switch bank so that they can be selectively connected and disconnected to the DRZ35ʼs amplifier. This feature is useful when paging into only one area or a few areas is desired. The user selects the zones to be paged, makes the page, and then can select different zones to get background music.
Connections Connecting a Speaker Load directly to the Amplifier Output (not using zone function): When the zone selection feature is not desirable, the speaker load can be connected directly to one of the amplifier output terminals on the Amplifier Output terminal strip (25V, 70V or 4-ohm). Connecting a single group of 25V or 70V speakers: The speaker load for transformer-coupled speakers are connected between the COM and either 25V or 70V terminal depending on the speaker type.
Connections Inputs: • AUX A stereo combining RCA pair are provided for connection of an external line level audio device. The AUX input works in conjunction with the MUSIC SELECT switch and the MUSIC control on the unitʼs front panel. • LINE A stereo combining RCA pair are provided for connection of an external line level audio device. The line input works in conjunction with the LINE control on the unitʼs front panel.
DRZ35 Operation FRONT PANEL CONTROLS: Power Switch The large power switch in the lower right corner turns the unit on or off. The ON indicator confirms the current state of the switch. Input Level Controls Separate input level controls are provided for Microphone, Line, and Music inputs. Use these 3 controls to set the desired audio levels between the three sources. Volume Control The large Volume control sets the overall system output level.
Digital AM/FM Tuner Operation TUNER PANEL CONTROLS: Power Button If the tuner section is currently off, press the POWER button to turn on the Tuner module. The Tuner module can be turned off separately from the main power button. Band Selection and Tuning Push the BAND button until the desired band (AM or FM) is shown in the display. Then use the DOWN and UP buttons to manually tune to the desired station.
