Midas HERITAGE 4000, Operator'S Manual

Page: 17 / 78

Both the lo-mid and hi-mid sections are selectable 1.5 or 0.5 octave equalisers.
- The High Pass filter frequency is continuously variable from 20Hz to 400Hz and is
enabled by pressing the HPF switch in. The HPF LED indicates the status of the HPF.
- When depressed, the insert point of the channel is engaged and the input return is connected to
the channel signal path.
- When the pre switch is depressed the insert is selected PRE-EQ, otherwise the insert is selected
POST-EQ (i.e. the signal passes through the EQ before the insert point).
- The EQ switch enables the channel equalisation (including HPF) when depressed or bypasses the
channel equalisation when released.
The Heritage 4000 has, in addition to the 8 stereo auxes, 24 assignable buss outputs which are discussed in
more detail later in this manual. Each pair of busses may be assigned:
Mono Auxiliary
Stereo Auxiliary
Stereo Group
This enables the Heritage 4000 to be used as an FOH, Monitor or FOH & Monitor console depending upon the
requirements of the user. The control over the assignable buss sends will change according to the status of the
buss output modules.
The buss send pot is a dual function switching pot. Pressing the odd or even numbered pot
will enable the buss send. When enabled, the buss send LED will light according to the
setting of the PRE switch. With the PRE switch depressed, the signal will be sent PRE-Fader
to the buss, otherwise the signal will be sent POST-Fader to the buss and the bi-colour LED
will represent this:-
GREEN - Buss send enabled and POST-Fader
RED - Buss send enabled and PRE-Fader
NONE - Buss send disabled

- The frequency centre of the EQ is continuously variable from 400Hz to 8kHz (hi-
mid) and 100Hz to 2kHz (lo-mid).
- Controls the gain of this EQ stage and is continuously variable from -15dB to
+15dB with a centre detent at 0dB.
- When depressed the bandwidth of the EQ section is set to 0.5 octaves or Hi ‘Q’.
Otherwise the bandwidth of the EQ is set to 1.5 octaves
The bass equalisation is selectable 1.5 octave or Midas shelving via the bell switch.
- The frequency centre of the EQ is continuously variable from 20Hz to 400Hz.
- Controls the gain of this EQ stage and is continuously variable from -15dB to
+15dB with a centre detent at 0dB.
- The bell switch selects between classic Midas Shelving EQ (bell switch OUT) and 1.5
octave bandwidth Bell EQ (bell switch IN).
The odd and even numbered buss sends control the level of signal sent to the buss. The buss
send is continuously variable from off (-inf) to +6dB.
NOTE: When in mono aux mode, a mono sum of the left and right inputs are sent to the buss.
