Effects: Kill, Cut/Punch; Outputs - Ecler SMAC PRO20 Manual De Instrucciones

4.7. Effects: KILL, CUT/PUNCH.

Two groups of switches (11) with leds (10) are placed on top of the sloped faders of
the SMAC PRO20. Each group acts on the correspondent channel. When the switches are
pressed, the selected frequency range is instantaneously eliminated. So, it is possible to mix
the bass of a song (by eliminating the medium and treble) with the medium and treble (by
eliminating the bass) of another song.
The CUT and PUNCH switches are also instantaneous. Each CUT switch (13)
instantaneously stops the adjacent channel if the fader and crossfader are open. The PUNCH
effect (14) is the inverse, the music is instantaneously inserted if the crossfader is closed
(opposite site of the switch pressed). The level of the punched channel depends on the channel
fader.
The combination of these three elements offers an incredible fan of possibilities for
your creativity.

4.8. Outputs

Headphones: in order to obtain a high performance, these should be of the high
impedance type (200-600Ω). Plug them to the HEADPHONES (30) output, in the front panel,
by means of a standard 1/4" stereo jack. Sleeve is Ground, Ring is Right Channel and Tip is
Left Channel.
The SMAC PRO20 has two outputs, OUT1 and OUT2 (22-23) with rotative
independent volume controls (3-4).
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 SMAC PRO20 mixing unit is factory adjusted to 0dBV/1V but OUT1 can be
internally adjusted to –10dBV/316mV, +4dBV/1.6V or +6dBV/2V (see Fig.2). Just changing
some soldering bridges.
The SMAC series mixers have a REC (24) output of -10dBV over 10kΩ of load for a
nominal level input.
ATTENTION: The modification of the output gain must be carried out by a qualified
technician.
