The ToolMix8 has 8 identical line inputs. All inputs are electronically balanced and can handle levels of more than + 30 dBu. A pot
with calibrated center detent controls the input gain. The gain control range is +/- 20 dB. The buffered, electronically balanced in-
sert point is driven from the output of the input amplifier. The insert output is always available on the connector panel. The insert
input is switched into the signal chain when the INS switch is pressed.
Unlike other line mixers that have a simple, passive input selection using
only a switch, the ToolMix8 has input amplifiers with gain control and an
insert section with balanced drivers that is located post the input gain. It is
therefore possible to control the level that is send to an external process-
ing device independent of the output level of the D/A converters. The D/A
converter level can remain on the original high level while the processing
device is driven by a different level.
The output of the insert switch feeds the fader, the peak present indica-
tor, the PFL switch and the two aux sends in parallel. Both aux sends de-
fault to pre fader; however, internal jumpers make it possible to set one or
both aux sends post fader as well. The peak present indicator is a 3 color
led that displays levels of more than - 20 dBu with green color. The color
becomes yellow at 0 dB and changes via orange to red when the level in-
creases. With red color, the remaining headroom is still 5 dB. The post fad-
er output is driven by the output of the channel fader, pre CUT switch. This
output can be used to record the input signal directly. With this operation
