EXP7x AEC Expander
The Rane EXP7x Expander for the HAL1x provides 8 channels of
full-featured, drag and drop Acoustic Echo Cancellation (AEC).
Each channel of AEC can be added to any HAL1x system input
and route to any Halogen DSP block, including the gain-sharing
automixer, manual mixer, regular Room Combine block, new
Conference Room Combine block.
The Rane EXP7x in combination with HAL1x and Halogen
software provides a conferencing solution including far more than
high-performance AEC.
Processing blocks to enhance the AEC system solution:
Revolutionary Conference Room Combine block with intrin-
sic support for conferencing.
Independent Far End mixers and AEC Reference selection
per room.
Far End gain-sharing mixer inputs and AEC reference auto-
matically change with room combinations.
Multi-channel and Tracking processing blocks mirror local
room processing in the AEC Reference signal path
Included are the Multichannel Shelving Filter, Multichannel
PEQ, Tracking Ambient Noise Compensation and Tracking
Side-chain Compressor.
Each AEC channel includes:
Mic and Reference Inputs with Level control & metering.
AEC on/off, plus adjustable AEC Threshold.
Soft / loud talker AGC & 5-band parametric EQ, plus high-
and low-cut filters.
Full bandwidth AEC with adjustable non-linear processing.
Ambient Noise Reduction (dynamic & steady-state) & howl-
ing prevention.
Complete metering: Input, Reference, Echo Return Loss
(ERL), Echo Return Loss Enhancement (ERLE) & Total Echo
Return Loss (TER).
20 to 20 kHz Bandwidth, 200 ms tail length.
<20 ms propagation delay, 100 dB/sec convergence rate.
Because EXP7x AEC channels are not associated with a particular
hardware input, preset recall can re-assign an AEC resource across
inputs / rooms as required. Drag and drop AEC supports the
typical one-AEC-per-microphone configuration. With optimum
acoustics, mic and loudspeaker placement, or with rarely used
mics (such as audience mics) it allows mixing more than one mic
into a single AEC channel, significantly reducing cost.
What's unique about HAL’s AEC?
Flexible drag-and-drop placement
Use it where you need it.
Intrinsic support for conferencing
