PREZONE2
Wiring - MIC A Input/MIC B Input
1. See Figure 5. Connect the microphone - the Euroblock accepts balanced
microphone or line level signals; the RCA jacks accept line level signals.
2. Set the MIC/LINE switch accordingly.
NOTE:
if the balanced input is left open, LINE should be selected to eliminate input noise.
3. The stereo unbalanced input signals are mono, summed and merged with
the balanced input into one signal which may be sent to all zone outputs.
4. Phantom power (48 V) may be applied to the balanced Euroblock by
pushing the phantom power switch.
5. Adjust the gain control so the clip LED does not illuminate when the signal
is at the highest level.
6. Adjust EQ as needed.
7. If necessary, activate the VOX circuitry by turning the VOX level control
until there is an audible “click” (
MIC A Input only
).
8. When activated, the VOX circuit will attenuate all lower priority sources
(MIC B, Input 1-4) by 30 dB in the zone(s) where MIC A is enabled.
9. Volume may be set using the front panel level control. MIC Input A or B
may be activated by pressing the respective MIC A or B select switch on
the front panel.
Wiring - Inputs 1-4
1. See Figure 6. Connect source inputs as required. Input 1 has
Euroblock connectors that
accept balanced line level
signals and RCA jacks that
accept line level signals.
Inputs 2-4 accept RCA only.
NOTE:
the balanced and unbalanced
signals are summed, while keeping the
stereo signal. Both inputs (Input 1) may be
used at the same time.
2. Adjust the gain control
so the clip LEDs do not
illuminate when the signal is
at the highest level.
Wiring and EQ - Zones 1 and 2
1. See Figure 7. Connect stereo outputs to either the balanced
Euroblock or unbalanced RCA connectors for Zones 1 or 2. Stereo or
Mono may be selected.
2. LO and HI tone controls may be adjusted via EQ knobs for either
zone.
