The AS16x12 is the most advanced automatic matrix mixer available today. Combining 16 automatic input channels, 12
output channels, and a full crosspoint matrix system into 2 rack spaces, the AS16x12 is a compact solution for a wide variety
of sound system applications. 15 nonvolatile preset memory positions mean complete flexibility and reconfigurability.
The 16 automatic inputs utilize the patented Proportional Gain plus Autoskew mixing algorithm* for seamless automatic
mixing performance. Input preamp gains i50dB and +30dB for both dynamic and electret microphones, and 0dB
for line level inputs. Gain trim range on the inputs is +15dB to -63dB plus off.
The crosspoint matrix allows any input (or combination of inputs) to be routed to any output (or combination of outputs).
Available crosspoint gains include -15dB, -10dB, -5dB, 0dB, +3dB, +6dB, and off. In addition to the 16 inputs, matrix
sources include the audio from the LecNet Expansion connector as well as an internal noise source.
The 12 outputs are balanced line level. Outputs 9-12 each have a mic/line level switch to make those outputs compatible
with mic level devices like some four channel tape recorders.
The AS16x12 features a wealth of programmable features. With 17 programmable inputs and 19 programmable outputs,
even the most sophisticated control schemes are straightforward. The programmable inputs can control input or output level
on any grouping of inputs or outputs, memory preset recall, matrix crosspoint switching, or various functions associated
with the built-in room combining capability. Programmable outputs can indicate either input channel activity or the current
state of a programmable input.
The AS16x12 has an RS-232 port for remote setup or control by a computer or other RS-232 compatible controller. More
than one AS16x12 may be coupled together for larger applications.
