volume ((Fig. 1, Ref. 2).
CH3&CH4 SELECTOR on DUAL: Channels CH3 and CH4 operate independently.
The signals on channel CH3 inputs will only be present on the CH3 amplified
output (Fig. 2, Ref. 8). Similarly for CH4.
Each channel will respond to its own pitch controls (Fig. 1, Ref.3) and Master
volume ((Fig. 1, Ref. 2).
CH3&CH4 SELECTOR on MONO: In this status, both “CH3” and “CH4” outputs (Fig. 2, Ref. 8) will have the same
amplified audio signal from the total of “CH3 INPUT” and “CH4 INPUT”, the
priority inputs “PRIORITY IN CH3” and “PRIORITY IN CH4”, however, they will
only operate and be present on their respective channels.
Each channel will respond to its own pitch controls (Fig. 1, Ref.3) and Master
volume ((Fig. 1, Ref. 2).
7. DIP SWITCH to select priority and set the output filter
DIP SWITCH 1&2:
VOX Priority Operation (CH_ Priority).
ON ‐ enabled VOX priority operation on the relative “PRIORITY IN CH_” input (Fig. 2, Ref. 3).
OFF ‐ disabled VOX priority operation on the relative PRIORITY IN CH_ input (Fig. 2, Ref. 3).
Note
Refer to Point 3 “Priority Input” for further information regarding VOX interaction operation with inputs
With regard to correspondence between the DIP SWITCH and the relative input/channel, refer to what has been
reported in the corresponding screen‐printed pane on the rear panel of the device.
DIP SWITCH 3&4:
PA‐HF filter function (CH_ LO CUT)
ON – High‐pass filter inserted on the respective channel.
In this status, a high‐pass filter of 400Hz ‐ 3dB will be applied to the respective channel.
This filter is particularly useful if only horn loudspeakers or only vocal signal diffusion is piloted.
OFF – High‐pass filter disconnected on the respective channel.
In this status, the entire audio band will be reproduced 20Hz‐20KHz
Note:with regard to correspondence between the DIP SWITCH and the relative input/channel, refer to what has
been reported in the corresponding screen‐printed pane on the rear panel of the device.
8. Loudspeaker line output terminal board
After selecting the operating mode (Fig. 2, Ref. 5), connect an adequate load to the respective output. Refer to
paragraph 5 “LOUDSPEAKERS CONNECTION”.
9. GND screws
It provides earthing of the mechanical parts of the unit if the power supply socket is not fitted with a “ground
plane”
Attention
Connection must be carried out by qualified staff.
