Release: This control adjusts the length of time that any channel
remains active (on) after signal level has dropped below threshold.
Release Time is adjustable from 150 milliseconds to 4 seconds.
Since channels activate very quickly (4 milliseconds Attack Time),
precise adjustment of Release Time may not be critical. However,
when using Logic Outputs to control external switching circuits
(such as cameras), moderate Release Time settings may provide
more appropriate timing (see Logic Outputs on next page).
Active Indicator (Channels 1~8): These dual-color LEDs provide
indication of two channel functions: channel active & peak level.
When a channel is assigned for automixing (gated) operation, the
Active indicator will light green whenever the channel is active (on).
NOTE: The Active indicator does not light green on a channel
assigned for manual (ungated) operation. See Channel DIP
Switches on next page. The Active indicator will also light red
whenever channel signal levels reach +10dB (8dB below clipping).
Use this feature to aid in adjusting the Trim controls (see below).
Master: This control adjusts the level of overall signal sent to the
Main Output. The Main Output level is also affected by automatic
NOM attenuation, which reduces the output level by 3dB for each
doubling of active (gated) channels. Optimum Master settings are
near the 12 o’clock position (unity gain) or below.
Trim (Channels 1~8): These controls adjust the channel gain
(0~60dB) to compensate for different input signal levels. For best
performance, adjust these controls so the channel Active indictors
flash red (+10dB) on occasional peaks. NOTE: Accurate Trim
control settings are essential prior to Threshold adjustment (see
Threshold below). Once Threshold has been set, individual
channel sensitivities may be fine-tuned using the Trim controls. If
input signals exceed normal operating range of the Trim controls,
assign the Pad switch (see DIP switches on next page).
Aux: This control adjusts the level of overall signal sent to the Aux
Output. The Aux Output may be assigned either ungated (pre) or
gated (post) signals from the channels (see Master DIP Switches
on next page). NOTE: Unlike the Main Output, The Aux Output
does not provide automatic NOM attenuation.
Level (Channels 1~8): These controls adjust the amount of signal
sent from the individual input channels to the mixer output section.
Optimum Level setting is near the 12 o'clock position (unity gain).
-20 Indicator: This dual-color LED provides indication of both
signal present & peak level at the Main Output. This indicator will
light green when (internal) signal levels reach -20dB (signal
present). This same indicator will light red when (internal) signal
levels reach +10dB (8dB below clipping). Use this feature to aid in
adjusting the Master control. For best performance, adjust the
Master control so the -20 indictor flashes red (+10dB) only on
occasional peaks in signal level.
Threshold: This control adjusts the minimum signal level
(threshold) at which channels will become active (gate on). The
Threshold circuit also has 6dB of hysteresis, which allows a
channel to stay open until the signal level drops below the
threshold by 6dB. This hysteresis reduces the tendency for a
channel to ‘flutter’ on & off when it detects a signal that is right at
the threshold level. Because of the hysteresis, different threshold
settings will be arrived at depending on how you adjust this control.
If Threshold is set fully clockwise, then turned counter-clockwise
until all channels are easily activated by normal signal levels, the
threshold will be as high above ambient noise as possible. If
Threshold is set counter-clockwise, then turned clockwise until no
channels are activated by ambient noise, the threshold will allow
for greatest channel sensitivity. The threshold is further controlled
by Adaptive Threshold Sensing (ATS). ATS monitors signal from
active channels and automatically adjusts the threshold to prevent
false activation of other channels. NOTE: Accurate Trim control
settings are essential prior to Threshold adjustment. Once
Threshold has been set, individual channel sensitivities may be
fine-tuned using the Trim controls.
On Indicator: When the Power Cord is plugged in, and power is
applied to the autoONE, the red On indicator remains lit.

AC Power Cord: The power transformer provides 27 Volts AC to
the mixer, and is detachable via a 5-pin DIN connector. The mixer
has two internal ‘self-resetting’ fuses (there are no user
serviceable parts inside the unit). If the internal fuses blow, they
will attempt to re-set after a short period. However, this may be an
indication that the mixer requires service.
Output section. When using multiple autoONE mixers within a
system, connect Main Output of one mixer to Stack In of the next
mixer, and so forth. All mixers except the final autoONE should be
assigned as ‘slaves’ (see Master DIP Switches below). For
balanced connection, wire high (+), low (-), and ground ( ). For
unbalanced connection, wire high (+) and ground to both ( ) & (-).
DC Out: This 6-pin Modular jack supplies ±12 Volts DC, for
powering certain other BIAMP products or other external devices
(see product manuals for power considerations). DC Out provides
100mA maximum current. Channel 1 override is achieved by
shorting pins 3 & 6 (see Logic Outputs on pg. 4).
Main Patch: This 3-conductor TRS ¼” phone insert jack is for
connection of certain BIAMP products or other external devices at
the Main Output section. The Main Patch jack is pre-Master Level,
and is wired Tip (send), Ring (return), and Sleeve (ground).
®
ADVANTAGE System One products require a single TRS ¼”
phone cable for connection. Other devices may require a special
‘Y’ cable. If a pre-Master Level output is desired, connect to Main
Patch with Tip & Ring (send) and Sleeve (ground).
Logic Outputs: This 9-pin Sub-D (male) connector provides logic
outputs from the eight channels, plus a common ground. When a
channel becomes active, the associated logic output turns on.
Logic Outputs are used to control external circuits for switching
speakers, cameras, or indicators (see Logic Outputs on pg. 4).
Patch (Channels 1~8): These 3-conductor TRS ¼” phone insert
jacks are for connection of certain BIAMP products or other
external devices to the individual input channels. Patch jacks are
pre-Channel Level, and are wired Tip (send), Ring (return), and
Sleeve (ground). Certain BIAMP products require TRS ¼” phone
cables for connection. Other devices may require special ‘Y’
cables. If a pre-Channel Level direct output is desired, connect to
Patch with Tip & Ring (send) and Sleeve (ground). Patch jacks
may be individually assigned pre-gate or post-gate signal (see DIP
Switches below).
Expansion: This 6-pin Modular jack is for connection to additional
autoONE mixers. When using more than one autoONE mixer
within a system, it is necessary for the mixers to share information
regarding active channels. This information allows the mixers to
properly perform NOM Attenuation & Adaptive Threshold Sensing.
When only two autoONE mixers are used, this connection requires
a single Modular cable (provided). When more than two autoONE
mixers are used, a multi-jack adapter is required (Biamp #9090027-00). The information shared is processed primarily by the
‘master’ autoONE. To prevent system errors, all other autoONE
mixers are assigned as ‘slaves’ (see Master DIP Switches below).
Input (Channels 1~8): These plug-in barrier strip terminals
provide the balanced mic/line Inputs to the mixer. For balanced
connection, wire high (+), low (-), and ground ( ). For unbalanced
connection, wire high (+) and ground to both ( ) & (-). Phantom
power (+24VDC) is available (see DIP Switches below), with +48V
phantom power as an option (Biamp #909-0012-00).
Main Output: These plug-in barrier strip terminals provide the
balanced line-level Main Output from the mixer. For balanced
connection, wire high (+), low (-), and ground ( ). For unbalanced
connection, wire high (+) and ground ( ), leaving (-) unconnected.
Signal level will be reduced by 6dB when output is unbalanced.
Main Output level is affected by the front panel Master control, as
well as by automatic NOM Attenuation, which reduces the output
level by 3dB for each doubling of active (gated) channels.
Master DIP Switches: These switches assign functions to the
mixer as a whole (when pushed up). Slave assigns the mixer as
an expander to a ‘master’ mixer. -12dB selects -12dB channel-off
attenuation (instead of -40dB). HP Filter assigns a high-pass filter
of 6dB/octave @ 170Hz. Last Mic causes the most recently active
channel to remain on. Aux Post assigns post-gate/level channel
signals to the Aux Output (instead of pre-gate/level signals).
Aux Output: These plug-in barrier strip terminals provide the
balanced line-level Aux Output from the mixer. For balanced
connection, wire high (+), low (-), and ground ( ). For unbalanced
connection, wire high (+) and ground ( ), leaving (-) unconnected.
Signal level will be reduced by 6dB when output is unbalanced.
Aux Output level is affected by the front panel Aux control, but not
by automatic NOM Attenuation.
DIP Switches (Channels 1~8): These switches assign functions
to the individual channels (when pushed up). Pad attenuates input
signal -18dB (line input). Ungated turns channel on (defeats gate).
Phantom turns on +24V phantom power (for condenser mics).
Duck Ch 8 (Channels 1~7 only) assigns channel signal to activate
-12dB attenuation on Channel 8 (ducking). Aux Off (Channel 8
only) removes Channel 8 signal from Aux Output (mix-minus).
Patch Pre assigns pre-gate channel signal to channel Patch jack
(instead of post-gate channel signal).
Stack In: These plug-in barrier strip terminals provide a balanced
line-level Stack In to the mixer. Signal entering here is combined
with signals from the input channels, and is then sent to the Main

LOGIC OUTPUTS
The autoONE provides eight logic outputs on a rear panel 9-pin Subminiature D (male) connector. Logic Outputs can be used to control
external switching circuits for speakers, cameras, indicators, etc. The autoONE Logic Outputs are most often used, in conjunction with
external relays, to turn off specific speakers when nearby microphones are active (reducing feedback problems). For example, if a speaker
is located directly above microphone #1, the Logic Output for Channel 1 of the autoONE can be used to turn off that speaker relay when
microphone #1 is active (see diagram on next page). The Logic Outputs can also be combined (wired in parallel) to control a single circuit.
For example, a speaker relay could be turned off when either microphone #1 or microphone #2 is active. In addition to speaker relays, the
autoONE Logic Outputs may be used to control external indicator lights (see diagram on next page). Another common application for
Logic Outputs is to control video cameras. Different cameras could be activated depending upon which microphone (or group of
microphones) is currently active. Cameras can be selected (using a video switcher such as a VSX41) and/or camera presets may be
triggered (using a ‘pan/tilt/zoom’ camera system). The Logic Outputs may also be used in conjunction with the DC Out or Expansion jacks
(pin 6 & pin 3) to perform ‘automatic priority’, which allows all other channels to be muted whenever the Channel 1 microphone is active
(see diagram on next page). The Logic Output (pin 1) & ground (pin 9) terminals for the Channel 1 ‘priority’ microphone are wired to pin 6
& pin 3 respectively of either the DC Out or Expansion jack. A switch or contact-closure may instead be used, for manual priority override.
The autoONE Logic Outputs are ‘open collector’ outputs. Each Logic Output is an NPN transistor with the collector being the output and
the emitter being ground (see diagram on next page). When a Logic Output is turned on, the transistor provides a path for DC current to
flow. The Logic Outputs do not provide any voltage or current. They act only as switches (with a common ground return). To activate
external relays, an external power supply must be used (see diagram on next page). The Logic Output transistors are rated up to a
maximum of 24 VDC and 50 mA per output (24 volt relay coils maximum). However, +12 Volts DC is sufficient power for most applications.
When using the Logic Outputs to control relays, protection diodes must be used to suppress high voltage transients that are generated
when the relays turn off (see diagram on next page). Any of the 1N4004 family of diodes (1N4001, 1N4002, 1N4003, 1N4004, 1N4005,
1N4006, 1N4007, or equivalent) will provide proper protection. A 12 Volt Power Supply (#909-0011-00), 12 Volt Relays (#310-0059-00),
and 1N4004 Diodes (#190-0003-09) are available from Biamp Systems. When a Logic Output goes on, the associated relay may be wired
to perform on, off, or ’A/B’ switching functions. To use logic ‘on’ to turn on (or activate) a device, wire across the ‘normally open’ relay
contacts, in series with the device (or control voltage source). To use logic ‘on’ to select between ‘A’ or ‘B’ signals (inputs or outputs), wire
one signal to the ‘normally closed’ relay terminal and the other signal to the ‘normally open’ relay terminal, with the common relay terminal
providing the feed (input or output).
The 9-pin Sub-D connector used for the autoONE Logic Outputs is the same type of connector used for RS-232 communications ports on
IBM compatible computers. A cable may be created by simply wiring to the proper pins of a female 9-pin Sub-D cable-end connector.
