These curves are designed to improve the quality of
the human voice. The ends of the spectrum are
shelving type, with 15 dB of action.
As brief reference we said that the knob LOW (or
bass) gives “body” and “weight” to the voices;
whereas the knob HIGH adds “presence” and usually
improves the intelligibility.
The central frequencies have a bell-shaped curve
(peak EQ). Mid-bass is centered in 160 Hertz, where
usually the popping effect are higher, or there is ex-
cessive resonance in certain male voices.
The mid-high band is located around 5 KHz, because
around this frequency usually appears the problems
with the sibilants.
3.5 Line channels
The Solidyne DX822 has four stereo LINE channels.
Line channels have two stereo inputs. Channels 4 & 5
have balanced stereo inputs (RJ45 connector) and
unbalanced stereo inputs (RCA), commutable from
the frontal panel.
Channels 6 and 7 have digital USB inputs, and stereo
unbalanced aux inputs with 1/8” Jack TRS. When the
jack is plugged, the channel switch to aux input and
the USB audio signal disconnects.
Line channels have gain adjustment that must be
settled to obtain 0VU with the fader working above
the OVL zone (the gray zone between -10 /-20 dB) to
avoid excessive amplification on preamps.
NOTE:
please see “2.2.2.2 – Digital inputs/outputs” and read
carefully the note about the USB audio levels in Win-
dows©.
To put a channel on-air; assign the channel to PGM
and raise the fader. The apropiate level is obtained
when the peaks of the signal reaches 0VU.

Microphone channels are
processed by a

OVERLOAD ZONE
The preamp gain must be
adjusted in order to the main fader
works over this indication. If fader
works always over the OVL
indication, there are “RISK OF

can be assigned to PGM,
to REC or to both outputs.
