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.
A jumper must be connected across the LINK terminals for these outputs
to work. A second jumper is typically connected across the GND and COM
terminals. This jumper can be omitted if it is desirable to have the speaker
signals float without a hard connection to the system ground.
Connecting a single group of low-impedance speakers:
The speaker load for low-impedance speakers are connected between the
GND and the 4Ω terminal. There must be no jumper installed across the
LINK terminals for the 4-ohm output to work properly.
Antenna Connections:
300-ohm / FM Antenna -
The included di-pole antenna or a 300-ohm antenna feed can be connected to these terminals.
75-ohm / FM Antenna -
A 75-ohm coaxial antenna can be connected to this F style connector.
AM Antenna -
The included AM loop antenna can be connected to these terminals
Signal Outputs:
• BOOSTER AMP OUTPUT
A mono RCA connector provides a line level output of the signal feeding the
DRZ35 power amplifier. This signal is typically used to feed the input of an additional
booster amp for systems that require more than the DRZ35ʼs 35 watts of power.
Since the additional booster amp is external to the DRZ35, the zone switches have
no effect on the output of this amp. The Booster Amp Output is affected by the
PRE/POST Volume switch, which allows the installer to determine if the Booster
Amp signal is affected by changes in the front panel volume control (Post Volume)
or not (Pre Volume). When using this output to supply an additional external amplifier,
the Post position might be desirable so that the output level of that amplifier
tracks adjustments to the DRZ35 volume control. If it is desirable to use the
volume control on the external booster amp to control its output level, then Pre
Volume should be used so that the input level to the booster amp does not change
with adjustments to the front panel volume control of the DRZ35.
• LINE OUTPUT
The LINE Output is a dual-mono feed of the DRZ35ʼs output for use with recording
devices or other amplifiers. The LINE Output is always Pre Volume.
WARNING:
4-ohm and 25V/70V outputs should
not be connected simultaneously.
Only one output to be used at a time.
