INSTALLATION:
STEP 1:
Connect the outputs (L/R) of the studio desk or the studio's output router
(what usually goes to the transmitter) to the inputs (L/R) at the back of the
EA946
marked "STUDIO".
STEP 2:
Connect the audio signal (L/R) coming from the AUX-source to the inputs
(L/R) marked "EXT".
STEP 3:
Connect the outputs of the unit marked "OUT" (L/R) to the inputs of the
transmitter or the line feeding the transmitter.
REMARK:
Make sure you do not reverse the LEFT and the RIGHT signals!
STEP 4:
Connect the START and STOP control outputs to the remote control inputs of
the AUX-source. The START and STOP outputs can be found on the 9 pin D-sub
connector marked "CTL_out" at the back of the
EA946
. Please note the polarity of
these optocoupler outputs.
STEP 5:
Connect a line coming from a home exchange or PABX to the socket marked
MONITOR I/O. If you want to use a direct outside line you have to use an officially
approved Telephone line interface, such as the EELA AUDIO
EA815/1
PTT approved
TELEPHONE HYBRID. This can be connected with the -for this purpose dedicated- 9
pin D-sub connector marked 'HYBRID I/O' of the
EA946
by means of a full wired 1 to 1
D-sub cable.
STEP 6:
Connect a RS232 cable between the RS232 port of an IBM-compatible
computer and the 9 pin D-sub connector marked "PC_port" of the
EA946
.
STEP 7:
Connect the 5 pin DIN connector of the Mains adaptor included in the delivery
to the connector on the unit marked "POWER". Before you plug the MAINS adaptor in
the socket, make sure the delivered MAINS adapter is suitable for your local MAINS
Voltage and Frequency. Now connect the MAINS power supply to the MAINS voltage.
The ON-led at the front of the
EA946
will light up to show the unit is in operation, and
after 3 seconds the internal buzzer will give a short beep to confirm the start up
procedure has been successful.
STEP 8:
Now install the Windows modulation guard programme in the way it is
described in the next chapter.
STEP 9:
Set the
EA946
in such a way as described in the chapter “making presets”.
The
EA946
