Main faders of all channels work with ETM-VCA tech-
nology (Electrometric-Voltage Controlled Amplifier).
The fader only manages DC, that controls an ampli-
fier of variable gain. This method guarantees very low
distortion and eliminates the noise by dust faders.
Complete information about the new ceramic fader
technology can be found at www.SolidynePro.com.
3.6 How to record
There are two stereo output channels. The main
channel is Program (PGM) and is used for ON-AIR sig-
nal. Usually, the bus REC is used for recordings. The
operator can make recordings while, simultaneously,
the console is on the air.
3.6.1 USB recordings
The main output (PGM) and the recording output
(REC) are available in digital format, through connec-
tions USB. When USB connects, Windows© will rec-
ognizes recording devices “USB Recording device USB
1” corresponds to Channel USB-1 and gives the PGM
signal. “USB recording device USB 2” corresponds to
Channel USB-2 and gives REC signal (check this in
Windows Control Panel/Audio and Sound Devices).
On the computer:
configure the recording software
to use Device USB-2 as recording device.
At the console:
route the channels that wants to
record to REC bus. The others channels remain as-
signed to PGM. Proceed as follows:
a) In Monitor Section assign the Control Room
monitors to the bus REC. To send REC to the
Studio, assign REC for Studio monitor.
b) Release PGM and assign to REC the channels
that wants to record (I.e. MIC-1 and Line-4).
c) Meanwhile the radio still on air through, for
example, the channel 5 assigned to PGM with
a musical program.
Now start the recording on the PC. To enable a MIC,
remember to press the button Master MIC-ON.
The recording level is visualized on the REC VUmeter
of the console and at the recording software. The in-
put level is fixed for Windows mixer. To adjust the
recording level, use the DX816 channel faders. Peaks
must reach 0 VU (0Vu = -15 dBfs).
RECORDING DEVICES DO NOT HAVE GAIN
CONTROL BY SOFTWARE
At the Studio the speaker can monitoring the sig-
nal using headphones or at loudspeakers. When
the recording ends, it can be checked using the
same REC bus, routing to REC the channel in which
the PC playing. At this point; be careful of not pro-
ducing a feedback loop in the computer. make sure
to mute in the pc (from windows mixer) all sources
of signal except “wave” and “gain control” (main).
When the work is finished, return all the controls
to the original position, to leave the console to the
normal way of operation.
3.6.2 Record a call
The DX816/822 allows routing the TELECOM channel
to PGM or to REC. It allows to record calls while a
musical program is on air. For make this, assign the
TELCO channel and a microphone to REC; and pro-
ceed with the communication as was explained in
“3.2 - Hybrid & Telco”. Assign the monitoring to REC
to listen to the communication (see previous issue).
