Biamp autoONE Specifications

The autoONE Automatic Mixer is affordable, extremely versatile, and easy to use.
NOM attenuation, adaptive threshold sensing, speech-frequency filtering, manual priority override,
selectable channel-off attenuation, and selectable last mic hold. The autoONE is compatible with all
other BIAMP products, providing the ultimate expandable system. The autoONE is covered by BIAMP's
five-year warranty.

ARCHITECTS & ENGINEERS SPECIFICATION
The automatic mixer shall provide eight balanced mic/line input channels. Each input channel shall include trim, pad, & level
controls, as well as a combined active/peak indicator and a TRS ¼" phone patch jack. DIP switches on each channel shall allow
selection of gating, 24V phantom power, & patch jack pre/post gate. Channels 1~7 shall be individually assignable to trigger signal
present ducking of channel 8 by 12dB. Channel 8 assignment to an auxiliary output shall be defeatable, to provide a mix-minus
capability. Each input channel shall provide a discrete transistor, differentially balanced mic/line preamp for low-noise & low
distortion, with connections via plug-in barrier strip.
Balanced main & aux outputs, as well as a balanced stacking input, shall be provided on plug-in barrier strips. The main output
shall include a selectable high-pass filter. The aux output shall be assignable to receive pre/post gate signal from the channels.
The stacking input, along with a master/slave switch & an expansion jack, shall allow linking of multiple units to increase the
number of mixer inputs. The expansion jack shall include a priority terminal for muting of all inputs, except channel 1, via an
external contact-closure.
The main output shall provide NOM attenuation, with automixing functions to include Adaptive Threshold Sensing, Speech-
Frequency Filtering, & 6dB of hysteresis, for increased stability of gating operations.
selectable last mic hold & -12dB/-40dB channel-off attenuation. Eight logic outputs shall be provided on a 9-pin Sub-D connector,
for control of external circuits based upon active status of the channels.
Frequency response shall be +0/-0.5dB (20Hz~20kHz @ +4dBu) THD+N shall be less than 0.05% (20Hz~20kHz @ +4dBu)
Output Noise shall be less than -75dBu (20Hz~20kHz, main & channel @ nominal) Power consumption shall be less than 15 Watts.
Dimensions shall be 1.75 inches (1 rack space) high, 19 inches wide, and 11 inches deep.
coverage shall be 5 years.
recommended grounding practices.
The automatic mixer shall be a BIAMP autoONE.
