Telephone Channels (Oxygen 3 And 3 St) - Axel Oxygen 3 Operating Manual

10 TELEPHONE CHANNELS (OXYGEN 3 and 3 ST)

The Telephone module features a built-in telephone hybrid.
The module features two gain controls, PFL, Master output, hybrid Hook / Ring controls. It
features connections to a regular telephone line (POTS) and to an external standard
telephone set (f.i. for dialling). Automatic line compensation is also featured.
The audio sent to the telephone caller is a mix-minus (N-1). The mix minus signal is the
programme output signal with the phone signal (caller's voice) removed.
The presenter can talk off-air with a caller (whilst the Main programme is being output) via its
own microphone (connected to Channel 1 module).
HOOK button: it allows Line hooking. This switch hooks / hangs up the hybrid from the
telephone line. Hook LED switchs on accordingly. The same LED blinks when a call (ring) is
coming in. Please note: LED glows only if phone line is connected.
SEND: It adjusts in the +/- 12 dB range the level of mix-minus signal which is sent to the
telephone caller.
RECEIVE: It adjusts in the +/- 12 dB range the level of the signal incoming from telephone
caller.
MEETING: it allows the RECEIVE signal to be heard also by the other telephone caller.
MASTER: it connects the telephone output to the Master output. The LED inside the button
turns on accordingly.
PFL Pre-fade listening PFL button (operated only in latched mode) allows a caller to listen to the
announcer/DJ microphone (connected to Channel 1) and to be heard without being in the broadcast
(i.e. with the fader closed).
When the PFL button is activated (with MASTER button deactivated):
the channel (Receive) signal will be connected to the PFL output (see also MONITOR Chapter).
-
the DJ MIC (i.e. the Mic connected to Channel 1 with A/B selection button released) is
-
automatically routed to the caller for "off-air" (i.e. 'Private') communications with the engineer or the
announcer (regardless of MST and PFL keys on the Micro 1 channel)
When the MASTER button is activated (regardless of the PFL key):
the Master bus is automatically sent to the caller
-
the caller is broadcast while Telephone channel fader opened
-
Note: with MASTER button enabled on Telephone channels, the signal sent to the telephone line (adjustable
through SEND control) will be the sum of the signals coming from each module routed to the Master bus
except from the two Telephone ones. The mutual phone-user listening can only be enabled via the
MEETING function (on both the Telephone modules).
SLIDER ALPS N-type 90° ultra smooth 100 mm sliders are provided on series.
