• Configurable size of 4, 8 or 12 faders (up to 16 or 20 faders for AEQ GRAND FORUM).
Conductive plastic faders 100mm.
• Internal sampling rate 48 kHz to 24 bits. Variable through external clock referente.
• Modular design that allows you to adjust the number of inputs and outputs of the
equipment to the requirements of each facility. Front removable modules for easy
maintenance.
o Up to 14 modules of multiple inputs and outputs, out of which 4 can be double
micro- line and 2 digital hybrid.
o Electronically balanced microphone inputs with phantom power.
o Electronically balanced analogue line Inputs and outputs. Adjustable gain ±
12dB. Balance/panoramic control selectable for all channels. Selective phase
inversion. Adjustable gain for up to 128 signals, including hidden signals.
o Transformer balanced digital inputs and outputs with adjustable gain ± 12 dB.
Balance/panoramic control selectable for all channels. Selective phase
inversion. Adjustable gain for up to 128 signals, including hidden signals.
o Sample rate converter (SRC) for all digital inputs. Supports AES/EBU and S-
PDIF digital signal formats.
o Additional input, integrated talk-back and auto-control micro-line.
o Integrated monitor and headphone outputs for control and studio. Cough mute,
ON-AIR signalling for studio and control, fader-start, remote PFL, talk-back,
automatic monitors muting. Monitoring can be configured for any of the system
signals.
o CUE output and integrated CUE speaker.
o Headphone outputs integrated into the chassis.
o PFL Monitor integrated in chassis.
o Optional 64 channels digital MADI optical fiber connection (available by means
of user license).
o Test tone (1KHz) generator.
o 8 Opto-coupled GPI´s and GPO´s and 4 relay contact GPO´s.
• 4 direct routing buttons on each channel.
• Internal Routing 64x64 mono, with additional capability for routing signals from the
optional MADI interface (available by means of user license).
• All signals assignable to any control channel.
• Configuration of up to 8 MPX internal buses.
• 2 precision stereo VU meters.
• Externally synchronized clock, timer and stopwatch.
• Control of external equipment (AEQ hybrids and audio codecs) integrated in the
programmable key section.
• Communication control via Ethernet 10/100 connection through TCP / IP protocol. For
more information see chapter “4. CONFIGURATION SOFTWARE” of this manual.
• Memory banks for mixer snapshots or settings of all the available signals: up to 7
available memories.
• Processing of audio signals including system defaults to the basic configuration.
o Audio processing capacity for up to 20 stereo signals (up to 12 in Fader and 8
hidden).
o All audio processes are predefined but always allow manual adjustment in real
time and associated non-volatile memory storage system.
o Audio effects are available: parametric equalizer, high and low pass filters,
compressor/limiter and noise gate.
• Noiseless natural convection. AEQ FORUM is particularly suitable for self-operation
formats.
• Optional redundant power supply.
