Auxiliary Send; Aux Input; Inserts; Talkover - Ecler MAC90v Manual De Instrucciones

4.5. Auxiliary send

The MAC90v is equipped with a stereo bus of auxiliary sends, AUX (6). This send is
factory preadjusted to postfader, this is, any change on the channel fader (12) affects the level
present at the output of the auxiliary bus AUX OUT (53). This setting can be internally modified
and converted to prefader by simply changing a jumper, as seen in the configuration diagram.

4.6. AUX input

An AUX IN (13, 48) allows the return of the signal once it has been processed by an
external effect. This input can also be used as a regular HIGH LINE level input. The bus to
which it is assigned can be configured with internal jumpers (see configuration diagram). It is
factory preadjusted to PGM bus.

4.7. Inserts

Plugging a 6,35 mm stereo jack to the INS connector (there is a connector for each of
the L left and R right channels (41, 42), the microphone signal can be redirected to a particular
effect for that input only. Sleeve is ground, tip is send and ring is return. If you use a mono
jack, instead of a stereo one, with the ring short circuited to ground there are two new
applications:
- If you plug the jack fully in, this works as an output, having a post-preamplifier signal and
cutting its way to the main mix bus.
- Plugging the jack "halfway in", only to the "first click", you get a direct post-preamplifier
signal, but the sound ALSO goes its way to the main mix bus.

4.8. Talkover

Assignment: The channels that have both XFA and XFB simultaneously depressed
(MIC indicator lit) automatically reduce the signal level of the channels that have the crossfader
buttons in any other position and of course have open faders. This happens at the first voice
"hit" of the DJ or speaker on the microphone plugged to the channel with both XF buttons
pressed. When the DJ stops talking the music level comes up to the initial level.
Usage: The talkover is enabled through the ON (32) switch, and has efficiency, EFF
(37), main signal level attenuation (between 0 and 30 dB) and recovery time, TIME (39), the
time necessary for a progressive come back to the original level (between 0,1 and 3 sec).

4.9. Outputs

The MAC90v mixer has two independent outputs, OUT1 and OUT2. Each one has its
own volume control, with a sliding fader for OUT1 (33), and a rotary one for the OUT2 (26).
Both outputs have a dedicated balance control BAL (29, 23).
You must be careful when setting up the general output level of the mixer. The "clip"
display of the connected power amplifiers must never remain permanently lit, but do it only
occasionally by following the rhythm of the bass signals that are being played.
The MAC90v mixing unit is factory adjusted at 0dBV/1V, although this output can be
internally modified to +6dBV/2V. See configuration diagram.
