Operation
1.
Proposed to install the master equipment in the major studio, LINE for call from outside
and PHONE for call from instructors.
Installation Setting
2.
Connect the studio box to the “DIRECTOR” interface of master equipment; connect the
living box to live ROOM1 and ROOM2 interface of master equipment. (Remark: The boxes for
studio and living are the same, just with the different interfaces connected to master
equipment.)
3.
Connect the master equipment’s audio Room1 out and Room2 out to the live audio’s
input of the module on a line (balanced or unbalanced Connection); But the master
equipment’s audio Room1 in and Room2 in should be taken from the live audio’s AUX OUT,
meanwhile,
the related AUX OUT‘s volume of the live audio’s hotline input module should be
the lowest. It could avoid the noise. If the live audio has the telephone module, it could be
connected to the telephone module’s in-out.
Remark: Mix out is for studio’s monitor if connect the amplifier.
4.
Level adjustment
If live audio’ broadcasts the normal range for the signal, adjust the panel‘s Tel Out Level
button to its normal level instructions, then hotline audience will get the right program signal.
Then adjust the Tel in Level button to 5.
Remark: If you find the audience voices is too low or too high, adjust the Tel in Level
button to its normal level indicating during the actual operation.
5.
Anti-side tone test
Do the anti-side tone test before operation.
Add the audio testing signal through the line-input to the hotline device, and connect the
Room Out of the hotline device to the mill voltmeter. Then there is a mill volt reading after
getting through and cut-in one line. Open the case and then adjust the each anti-side tone
matched resistance and capacitor according to below location map to reach the lowest mill
volt reading.
Remark: There are 64 mill volt readings from 2000PF to 0.2uF through adjusting the
switch. The reading is high-to-low from left to right according to the location map below.
