Alesis 1622, Reference Manual

8

The SUB MASTER Faders can serve several different functions, depending upon the
application.  In sound reinforcement or in recording during mixdown, the SUB MASTER Faders
will act as a group master for a number of input channels.  For instance, if Input Channels 1
through 8 contained drum mics, and you wanted to control the overall level of the drums with just
one fader, this could be achieved by assigning input channels 1 through 8 to the SUB MASTER
ASSIGN, and then panning each channel either hard left or hard right (for mono).  The SUB
MASTERS could also be assigned in stereo by panning the input channels to any point in the
stereo spectrum, in which case the composite signal will appear on both the right and left SUB
MASTER faders.  

See Section 3.

During recording, the SUB MASTERS can be used to mix several signals together onto a single
track (or two tracks for stereo) by assigning those input channels to the SUB MASTERS and
connecting the SUB OUT jack to the track that you wish to record on.  

See Section 3.

SUB MASTER TO MASTER ASSIGN SWITCH

This switch routes the signal on the SUB MASTERS to the MASTER Faders.

MASTER FADERS

The Left and Right MASTER Faders control the main output of the console to either the mixdown
deck (in recording) or the sound system (in sound reinforcement).

MAIN STEREO METERS

The main STEREO METERS, each consisting of 7 green, 4 yellow, and 4 red LEDs, show the
relative output levels of the MASTER Faders.  The METERS will also show the level of any input
channel that has its SOLO engaged.

SOLO/POWER LEDS

The SOLO LED lights whenever a solo is switched on.  The POWER LED lights whenever AC
power is connected to the unit.

MIC/LINE INPUTS

Channels 1 through 16 can be accessed via a 1/4" phone jack.  Normally, this would be used for
line level signals such as synthesizers or tape machines but it is also possible to feed a
microphone signal into this jack.   In 4 or 8 track recording applications, channels 9 through 16
would normally be used for tape returns of tracks 1 through 8, while channels 1 through 8 would
be used for mic or instrument inputs.

MICROPHONE INPUTS

 Channels 1 through 8 contain an XLR jack which provides an electronically balanced input
ideally suited for a microphone.  

This input is overridden should a plug be inserted in the

corresponding Input phone jack

(XLR #1 is defeated if a phone plug is inserted in phone jack

#1).

DIRECT OUTPUTS

Channels 1 through 8 contain a DIRECT OUTPUT jack.  Each channel routes its own input
signal, after it has been amplified and EQ'd, to the Direct Output jack.  This is generally used to
feed a single track of a Multitrack Tape Deck.  Because the Direct Output is the path with the
least amount of circuitry and therefore the lowest possible background noise, it is most desirable
to use when recording the signal of only a single channel.

CHANNEL INSERTS

Channels 1 through 16 each contain a stereo jack called an INSERT.  This consists of an insert
send (the tip of a stereo phone plug) and insert return (the ring of a stereo phone plug) and is
used to insert an outboard effects device, such as a compressor, EQ, or chorus, directly into the
