DRZ35 Operation
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. The relative mix level
between the three input sources is not affected by this control.
Level Meter
Next to the Volume control is a 5-segment output level meter. This meter helps in
setting the maximum level of the system. During loud passages of audio, the output meter
should not exceed the 0 dB segment. When this segment is on, the output from
the amp has reached its designed maximum output voltage level. Generally exceeding this
level can cause noticeable distortion in the audio program and exceeding this level con-
tinuously may cause temporary thermal shut down of the amp as a protection measure.
If the system output level is very low, the level meter may not light any segments.
Bass & Treble Controls
Use these controls to adjust the amount of high and low frequency content heard
through the speakers. The 0 position on the control provides no cut or boost to that
frequency band.
Music Select Switch
Use the Music Select switch to choose between feeding the Tuner signal or the rear
panel AUX input signal to the Music Input. Use the Music Input Level control to adjust
the relative volume of the selected input signal.
Speaker Zone Select Switches
The Speaker Zone Select switches are push-on/push-off type switches. Any number
or combination of these switches can be selected to control which zones in the facility
receive the audio program. When the zone is selected, the button is sunken flush with
the front panel. When the zone is not selected, the button noticeably protrudes from the
panel. See Page 6 for more important information on connecting speakers to the Zone
Switch Bank.
