calibrated also produce interference in which you
can hear the transmitted audio (due to the misalign-
ment a part of the FM modulation is translated to AM
modulation).
Solution: D-816 consoles have internal filters
against RF interference. Therefore, if interference’s
appears, normally is caused by installation problems
on the transmission station that generate elevated
currents in the wiring of audio on the Studies, due to
the standing waves. These currents circulates inside
the cabinet of the console, and interferes to the cir-
cuits when overpass the barriers that impose to this
currents the built-in RF filters. The solution, then,
must be external to the console.
The solution is to acquire ferrite
O-rings of 60 mm diameter, to
allow passing the cables and
connectors. They will be used in
each connector, of input and outputs. The total set of
cables that goes to each connector, will have to be
twisted around the ring.
2.2 REAR PANEL – connecting
2.2.1 Power Supply
At the left side of the rear panel you will find the con-
nector for the power supply. The switching power
supply (provided with
the console) works with any
AC network (90-240 V) and tolerate zones with great
variations of tension. Gives
regulated 28 VCC.
PLEASE DONT REPLACE THE ORI GI NAL
POW ER SUPPLY.
The console does not have On/Off switch; reason
why it remains fed while the power supply is connec-
ted.
The grounding made through a bronze tip located in
the rear panel that provides the ground connection to
the chassis. Use cable of 2mm to a good buried coo-
per bar.
2.2.2 Input channels
On the rear panel are located all the inputs and out-
puts connectors.
Take in mind that good connections offer safe and free
of faults operation. By this reason we recommend you:
take it the time necessary to make the connections care-
fully and use always material of first quality.
2.2.2.1
LINE
inputs
Each line channel has two stereo inputs, selected
from the frontal panel. The
‘BAL-LINE' inputs are
symmetrical balanced. These called “LINE” are un-
balanced inputs.
To connect an equipment with balanced output you
will need a cable from DIN-5 to two CANNON (XLR)
or stereo Plug’s (TRS ¼”) according to corresponds.
The pin distribution of DIN-5 and XLR are described
next. Remember that you need to connect TWO XLR
to the DIN (balanced left and balanced right).
DIN 5 (stereo bal.) FEMALE XLR
1 AUDIO (-) RIGHT 1 GND (shield)
2 GND (shield) 2 AUDIO (+)
3 AUDIO (-) LEFT 3 AUDIO (-)
4 AUDIO (+) RIGHT
5 AUDIO (+) LEFT
Inputs called ‘LINE' are unbalanced. They use connec-
tors type “RCA”. Equipment with outputs of -10 dBV @
10 KOhms can be connected (home type or semi-pro).
The GAIN control is common for both inputs; that is to
say, that operates on the selected inputs.
2.2.2.2
USB
DIGITAL INPUTS
Digital channels 6 and 7 are for direct connection to
the computer using
USB ports.
Standard cables USB A/B are used. Ports 1.1 or 2.0
are supported. Place the CPU so next to the console
as it will be possible, in order to use cables of 2 to 3
meters of length. If it were necessary, can be used
USB extension cables; but it is recommended
not to
exceed 4 meters.
The channels must be connected to a computer run-
ning Windows© XP; starting by channel 6.
When
only one channel is used; channel 6 must be
always used.
When connecting the channel to the
PC, Windows© automatically recognizes it and ins-
talls the correspondent drivers. Additional drivers are
not required.
