1.3 Monitoring
The section “Monitor” have the controls to route
the signals to the loudspeakers and headphones of
the Studio and the Control Room. The section also
contains the controls for previous listening (CUE),
talk-back and Master MIC-on. The talk-back micro-
phone shares with the CUE circuit, to talk privately
from the hybrid with calls.
Using the controls located in the section ·
Studio
Monitor·
the operator selects the source of signal to
be listened into the Studio (ON-AIR, PGM, REC or
CUE). The mixer sends CUE signals to the head-
phones and loudspeakers monitors at the studio.
Into the Studio, a
headphone amplifier
(optional
item Solidyne HD3 & HD5) is in charge of manage
the signals of the loudspeakers monitors and head-
phones (see
2.5.1 – Monitoring into the Studio
and
4.- Monitoring dock Solidyne HD3 & HD5
).
The knobs at the “
Control Room”
section manages
the levels for the headphones and loudspeakers.
The switcher allows to select the audio source: ON-
AIR (input for external tuner), PGM, REC or CUE.
CUE:
The circuit CUE allows to listen the signal pre-
vious to the main fader (PFL).
The signal CUE can be
send to the Studio. At the Control Room, the opera-
tor can listen CUE on speakers or by headphones.
The output
Tally Light
gives 12 VDC when the Mas-
ter MIC-on button is on. In addition, the console has
an on-board tally light (see
2.5.3 – Tally Light
).
1.4 GPIO
DX816/DX822 allows starting remote devices when
certain channels are on-air (MIC-1; MIC-2; MIC-3;
LINE 1 and
LINE 2). It allows to command the on-air
playout software; digital audio processors (like
Soli-
dyne APC 542
); old CD/DAT/Minidisc players or oth-
ers specific peripherals like the video switcher
Soli-
dyne
SmartCam
.
Models /AoIP uses Ethernet to send the signal
“MICs on air” to the audio processor, in order to
switch the audio processing preset to a voice pro-
file.
1.5 ETM – VCA faders
The faders are “feather touch” with the technique
of
control ETM-VCA
(Electrometric Voltage Con-
trolled Amplifier). The faders DO NOT manage audio
signals. The variation of the level is made by means
of amplifiers of low noise and great stability. The
main faders only handle control signals that modify
the gain of the electronic amplifiers (please visit our
web site for details). The main advantages of this
technology are:
•
Eliminates the noisy signals due to dirty faders.
•
Eliminates the maintenance and improves the
life of faders.
•
Gives a perfect stereo tracking (less than 0,1 dB
error) between Left and Right channels.
•
Allows using Conductive Ceramic faders of ten
million guaranteed operations.
2. Set up and connections
2.1 Overview
Installation of Solidyne audio console doesn’t present
particular problems. However, keep in mind the basic
rules for all professional audio installations.
Do not connect the shielding of the audio wires
with the general ground of the electrical instal-
lation. The console provides this union through
a grounding terminal. See "2.3.4 - General dia-
gram for grounding".
2.1.1 About the use of RJ45
The consoles come with their inputs and outputs with
RJ45 connectors and are wired using multi-pair
shielded cable CAT-5. With the advent of audio over
IP (AoIP) many manufacturers started using RJ45 con-
nectors and shielded multi-pair cable to replace dif-
ferent audio connectors, to standardize the entire in-
stallation with a single type of connector and a
unique type of cable.
Additionally, the use of structured cable for connec-
tion between remote devices facilitates the installa-
tion anywhere in the world, due to availability of
components and assembly tools used for data net-
works.
The multi-pair cable end that connects to the audio
device (microphones, speakers, playback devices) still
require standard audio connectors. For this reason,
the RJ45 cable provides termination sections with
RJ45 female at one end and a standard audio connec-
tor according the needs at the other end.
