MONO INPUT CHANNEL SECTION
The following section details each part of the TXM16 and
TXM20’s INPUT CHANNELS including the 3-BAND EQ, the
MONITOR and EFX sends, PAN, GAIN and VOLUME con-
trols.
1 - SIGNAL LED
The TXM16 and TXM20’s MIC/LINE pre-amp also includes
a SIGNAL LED which, when illuminated, indicates that the
signal is present at the input.
2 - GAIN Control Knob
The TXM16 and TXM20’s pre-amp stage has a variable
GAIN control with a range of -6 to -50dB on the MIC input
and +14 to -30dB on the LINE input.
3 - LOW CUT Switch
Each of the TXM’s channels include a LOW CUT (or high
pass) filter which rolls off the low frequencies from 75Hz
and below at the rate of 18dB per octave.
4 - Channel Equalizer
The TXM16 and TXM20 mic/line input channels incorpo-
rate a 3-band, swept-mid equalizer allowing you to adjust
the high, mid-range, and low frequencies independently
on each channel. The frequency centers, range of boost or
cut, and equalizer type for each band are described in the
following section.
HF (HIGH FREQUENCY) 12kHz +/- 15dB Shelving type
The channel’s HIGH frequency response is flat when the
knob is in the “12:00” position. Rotating the knob towards
the right will boost the channel's high frequency response
at 12 kHz by 15dB, and rotating it towards the left will cut
the high frequency by 15dB.
MF (MID FREQUENCY) CUT & BOOST
The MID CUT & BOOST knob is used in conjunction with
the MID FREQUENCY knob to create the tonal shape in
the mid-range frequency when using the mono channel’s
equalizers. You can adjust the frequency on the mid-
range control with the FREQ knob, and use the MF CUT
& BOOST to either boost or cut that frequency by plus or
minus 15dB. The channel’s MID frequency response is flat
when the MF knob is in the “12:00” position.
FREQ (MID FREQUENCY) Variable 100Hz – 8K
The MID FREQUENCY is a control enabling you enhanced
capabilities in the tonal shaping of the input channel
signal. Thanks to the MID FREQUENCY control, you have
a variable mid-range equalizer, allowing you to pin point
the exact frequency you want to boost or cut. The MID
SWEEP has a “fixed Q” of two octaves (the amount, or
width, of frequencies around the center point that are
effected by the MID CUT & BOOST control) and can be set
in a range from 100Hz to 8Khz.
LF (LOW FREQUENCY) 80Hz +/- 15dB shelving type
The channel’s LOW frequency response is flat when the
