INTRODUCTION
The AM16/12 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 AM16/12 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 Lectrosonics 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). Various crosspoint gains settings are available. 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 AM16/12 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 AM16/12 has an RS-232 port for remote setup or control by a computer or other RS-232 compatible controller.
More than one AM16/12 may be coupled together for larger applications.
