AEQ FORUM
Digital audio mixer for broadcast applications
16
These four keys can have two working modes, that are selected from the Configuration
Software (see section 4.2.4 of this manual):
o Normal: each key pressed adds the signal to be monitored to the summing
bus.
o Exclusive: each key pressed connects the signal to the summing bus and
disconnects any signal previously selected.
2.1.2.6. Talkback.
Talk-back section allows the console operator to communicate directly with the studio and
remote guests (lines).
The default intercom channels for the AEQ FORUM are between the control room and the
studio, independent between monitors and headphones. You can set additional channels of
intercom to facilitate communications. For example, talk-back can be established between
studio or control to the different audio returns to hybrids or audio-codecs. The talk-back
microphone can also be used as an auto-control microphone if so defined.
The talk-back section of the control surface consists of 4 key buttons immediately beneath the
Studio and Control sections and the encoder “LEVEL” (Talkback Level) of the Studio monitoring
section.
From left to right are:
• “MON“: talk-back to studio monitors.
• “HP“: talk-back to studio headphones. The default configuration of the AEQ FORUM
does not differentiate between primary and secondary headphones. It is possible to
establish a secondary group of headphone creating a salvo to be triggered from the
programmable keys.
• “TEL 1“: talk-back to the telephone hybrid line 1 (AEQ FORUM allows a maximum of 2
single line digital telephone hybrid modules FR33, but has 8 MPX internal buses hidden
that can be used with dedicated lines, external audio codecs or telephone hybrids. The
talk-back to dedicated lines, external audio-codecs or telephone hybrids can be
established through the use of the programmable keys).
• “TEL 2“: talk-back to the telephone hybrid line 2.
2.1.3. Ventilation grille.
The base of the equipment and the top of the control surface have micro-perforations to allow
the passing of a stream of air naturally created by convection due to the heat dissipated by the
equipment electronics. The distance form the equipment base to the table top has to be
respected by at least the height of the equipment rubber feet and it is paramount not to obstruct
the ventilation grille on the top of the control surface.
