MX2400 has an excellent talk-back channel with
studios which operates by a private independent
channel. There are two ways to use it.
When transmitting mono streaming, talk-back MIC is
mixed with the digital transmission, so it can not be used
as independent channel.
a) Land line calling
The phone line is connected to the RJ-11 on the rear
panel. Incoming calls will light the LED located
beside the 'PHONE' button. To take the line press
'PHONE'. Open the fader 'STUDIO' (in the
headphones mixer) to listen the calling on
headphones. Pressing 'Talkback' activates the built-
in microphone. This communication is private, if the
link with studios is a stereo streaming (talck-back can
not be used with mono streaming).
To make a call from MX2400, press 'PHONE' and
dial using the DTMF keypad. The conditions of
privacy with respect to digital streaming are the same
as before explained.
b) Cell phone calling
In this case, you uses a Bluetooth cell phone to make
a private link to studio (see 3.6.1 – Using a Bluetooth
cell phone).
You can speak from internal MX2400 talk-back mic
by pressing 'Talk-back', and hear the return from
studios in headphones, opening the knob 'BLUETH'
(headphone mixer). Simultaneously with talk-back
microphone, at the studios will be heard the MX2400
transmission.
Remember that Talk-back only can be used with stero
streaming (not mono streaming).
