2.7.1 Rejection factor (Null)
This adjustment is only for LAND lines. The rejec-
tion factor expresses the capacity of the hybrid to
avoid that the transmitted signal returns distorted
to the mixer. As greater this factor is, more “clean”
will be the sound of the local speaker on the air. In
order set the rejection, proceed as following:
1. Assign the TELECOM channel to REC.
2. Make a calling using the DX822’s Hybrid.
Someone into the Studio must dialog with
the caller. Increase the level of fader Chan-
nel 8 until the voice of the caller reaches
0VU in REC vumeter.
3. Listening the voice of the local speaker in
REC, turn carefully the preset NULL until
find the point in which the sound quality is
the same that the obtained with channel 8
off-air.
4. This adjustment change for each phone line,
so if the line is changed, the adjustment
must be repeated.
2.7.2 CONNECTING A CELL PHONE
Any Bluetooth cell phone can be linked to Solidyne
DX822. While the phone can be up to 5 meters
away from the console, is recommended leave it
near to the console, but not over the console .
The procedure to link the phone to the console is
similar to that used for other Bluetooth devices.
When the cell phone pair to the console, creates a
link between the two devices, and the phone
stores the ID of the console. This operation is
performed only once (for each cell). Once the
console and phone are paired, the console
automatically connects to the phone when the
Bluetooth link is enabled on both devices.
DX822’s BLUETOOTH IS POWERED BY USB CON-
NECTION. (CHANNELS 6 or 7). IF NONE USB CHAN-
NEL IS CONNECTED TO A COMPUTER, CONNECT
AN EXTERNAL USB POWER SOURCE TO ANY USB
CHANNEL IN ORDER TO FEED THE BLUETOOTH.
