Input Channel The Equaliser

HIGH Frequency

Section – Shelving

Adjusts the high frequency shelving

EQ response. The Frequency con-

trol selects the corner frequency of

the shelving fil er (between 1kHz and

15kHz) and the Level control adjusts

the cut/boost b/- 15dB. The

centre “0” position of the Level con-

trol has a detent to indicate that it is

having no

eff

ect on the associated

channel signal. Cut or boost of the

high frequency Level control is usually

used for minor tonal adjustments.

LOW – MID

Frequency Section

Adjusts the low-mid frequency EQ

response. The Frequency control

selects the centre frequency of the

fil er (between 100Hz and 1.5kHz)

and the Level control adjusts the cut/

boost b/- 15dB. The centre

“0” position of the Level control has

a detent to indicate that it is having

eff

ect on this frequency band. The

bandwidth of this fil er is approxi-

mately one octave. The low-mid fre-

quency controls are used for minor

tonal adjustment or repair of a specif-

ic band of frequencies.

LOW Frequency

Section – Shelving

Adjusts the low frequency shelving

EQ response. The Frequency control

selects the corner frequency of the

shelving fil er (between 40Hz and

650Hz) and the Level control adjusts

the cut/boost b/- 15dB. The

centre “0” position of the Level con-

trol has a detent to indicate that it

is having no

eff

ect on the associated

channel signal. Cut or boost of the

low frequency level control is usually

used for minor tonal adjustments on

mixdown (remix).

HIGH – MID

Frequency Section

Adjusts  the  high-mid  frequency  EQ
response.  The  Frequency  control
selects  the  centre  frequency  of  the
fil er  (between  700Hz  and  10kHz)
and the Level control adjusts the cut/
boost b/- 15dB. The centre
“0” position of the Level control has
a detent to indicate that it is having
no

eff

ect on this frequency band. The

bandwidth of this fil er is approxi-
mately one octave. The high-mid fre-
quency controls are used for minor
tonal adjustment or repair of a specif-
ic band of frequencies.

INSERT ON

When depressed, this switch places
the rear panel channel TRS insert con-
nector in line with the signal path. This
insert point by default is after the chan-
nel EQ (unless it is selected pre EQ be-
low). By routing the signal through this
connector, the insert may be used for
applications such as an

eff

ect that can

be switched in/out. In the event the
user wants to patch in his/her favourite
external EQ, it can be connected to the
channel insert TRS and activated with
this switch, it could be used in conjunc-
tion with or without the Trident EQ.

Channel Equaliser

A four band fully sweepable

Trident EQ with overlapping ranges

is provided with a switchable high

pass fil er. The HIGH and LOW

sections of the equaliser have a

shelving response and the MID have

a peaking (Bell) response.

HPF

When selected, inserts a high-pass (or
low-cut) fil er with a corner frequency
50Hz and a roll off rate of 18dB per oc-
tave into the signal path. This control is
used to remove unwanted signal con-
tent below 50Hz. The result is usually
improved signal quality of the associ-
ated input signal, while decreasing the
low  frequency  amplific tion  demand
of  the  audio  systems  amplifier and
speaker  combination.  Mainly  for  use
with  microphones,  this  helps  remove
low  frequency  rumble  and  handling
noise.

EQ IN

This switch inserts the 4-band EQ
and High Pass Filter into the channel/
monitor (see EQ TO MON switch de-
scription below) signal path. When not
in use, it is suggested that the EQ be
kept in the OUT position for best phase
performance.
