Use Of The Crossfader; Outputs - Ecler MAC70i Notice D'emploi

4.4. Use of the CROSSFADER

The MAC70i provides a short travel sliding potentiometer placed horizontally. This
potentiometer is called CROSSFADER (26) and enables a direct mixing of the signals present at
channels 3, 5 and 4, 6. This allows the disc-jockey to prepare the mixes in the turntables and switch /
mix from one to the other by simply moving the CROSSFADER.
Two switchers, at each side of the CROSSFADER (24 and 30) allow for the selection of
the active inputs assigned to each of the CROSSFADER's sides.
The MAC70i's CROSSFADER has the great advantage of being removable and replaced
on-the-field from the outside. In order to replace it, just follow these instructions:
1- Remove the screws of the plate that hold the CROSSFADER.
2- Remove the set from the mixer.
3- Detach the multipin connector.
4- Replace the whole set or remove the screws that tie the potentiometer.
5- Tie the new potentiometer and the associated printed circuit and multipin
connector to the plate.
6- Attach the multipin connector.
7- Place the set on the mixer.
8- Fix the screws of the plate.

4.5. Outputs

The MAC70i mixer has two independent outputs, OUT1 and OUT2. Each one has its own
volume control, with a sliding fader for the main output (21), and a rotary one for the output 2 (12).
Each of the outputs also has its own balance control (17 and 10).
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 lighten up, but do it
occasionally by following the rhythm of the bass signals that are being played.
The MAC70i mixing unit is factory adjusted at 0dBV/1V, although this output can be
internally modified to -10dBV/0.316V, +4dBV/1.6V or +6dBV/2V. See 4.7.2.
The OUT1 (32, 42) output is balanced, with the following pin sheme:
Hot or direct signal
Cold or inverted signal
Ground
The balancing circuit simulates a transformer, so if you want to use OUT1 in non balanced
mode you must short circuit to ground the pin from the non-used output, else the output signal will
not have the desired level nor quality.
OUT2 (43) output is NON-BALANCED OR ASYMMETRICAL.
The MAC70i has two recording outputs: REC1 before the talkover (no channel signal is
present so it does not activate the talkover and so it does not attenuate the output) and REC 2 which
is affected by the talkover.
Finally, a L+R (19) switcher converts the stereo signal into mono or makes it present to
only one of the two channels. This switcher affects the OUT1, OUT 2 and REC 2 signals.
