DISTRIBUTION AMPLIFIER/ZONE MIXER/MIC SPLITTER DA-410.
MONITOR SIGNAL VU-METER
The selected monitor signals drives a Stereo calibrated VU-METER ranging
from -12 dB, -6 dB, 0 dB, +3 dB and +6 dB. (0dB ref. 0 dBu). This 6 led VU-METER is
connected pre-monitor level and is intended for precise signal calibration. Refer to previous
paragraph about MONITOR SIGNAL SELECTOR.
MONITOR LEVEL CONTROL
The selected monitor stereo signal incorporates a stereo level control placed
at the front panel in order to control the headphones output level, or the miniature
speakers volume.
NOTE:
In order to avoid breaks, never leave disregarded the monitor output level control. Avoid
prolonged saturation.
HEADPHONES OUTPUT
The headphones output are carried out by means of a stereo jack placed at the
front panel. This output can manage high impedance (100
Ω
- 600
Ω)
standard stereo
headphones.
The signal that appears in the headphones output is the chosen in the monitor
signal selector and the level could be regulated with the monitor level control.
Upon introducing a stereo jack in the headphones output, automatically the miniature
speakers are disconnected.
MINIATURE SPEAKERS
The monitor listening of the selected signal, drives a pair of stereo
miniature speakers placed at the front panel. The volume control of these
miniature speakers is carried out by means of the monitor level control. Upon
introducing a stereo jack in the headphones output, automatically the miniature
speakers are disconnected.
This stereo monitoring system allows a simple and efficient control of audio continuity in
moderate noisy environments.
NOTE:
In order to avoid breaks, never leave disregarded the monitor output level control. Avoiding
extend saturations. Avoid prolonged saturation.
MIC/LINE INPUT SIGNAL SELECTOR
The MIC/LINE input signal selector, placed at the rear panel, allows choosing
between line input signals or microphone input signals. The distribution amplifier/zone
mixer/mic splitter incorporates one mic/line input selector switch per input. Normal
position corresponds to line mode, and depressed to microphone signals inputs.
Nominal gain is 0 dB when line mode and +12 dB when configured as Mic.
Due to the reduced gain (+12 dB) in MIC mode, the DA-410 output signals must be externally
connected to preamplifiers or mixers into its MIC inputs.
