8 Channel Automatic Matrix Mixer
"Off". The gain change resolution is 1dB. In the case of Increase Out 1dB, each contact closure will increment the
output(s) gains by 1dB until 0dB is reached. Decrease Out 1dB will decrement the output(s) gains by 1dB until either
"Off" or Rear Panel Minimum Output Gain is reached. If the contact closure is pushed and held, it will continue to
increment or decrement until it is released or the gain reaches its high or low limit. The screen shown below indi-
cates that the function of programmable input 1 is Increase Out 1dB control of all four outputs.
Preset Recall - Allows one of the 8
AM8/4 memory presets to be recalled
by a momentary contact closure on a
programmable input pin. If you are
using two or more programmable inputs
for memory recall, you will want to set
up and apply all programmable input/
memory preset association and down-
load the active setup to all preset
memories you'll be using. This guaran-
tees that the desired programmable
input/memory preset associations are
stored in all memories of interest. The
screen below shows that the function of
programmable input 1 is to recall AM8/4
Memory Preset 1.
Toggle Crosspoint Gain - Allows for a
temporary matrix connection to be
made between one input and any
combination of outputs, at 0dB
crosspoint matrix gain. The first
momentary contact closure on the
programmable input pin will make the
specified input-to-output(s) connection,
and the next momentary contact
closure will remove the connection. No
matrix crosspoints other than the ones
specified are changed. This toggling of
input-to-output(s) connections is ideal
for applications such as single or multi
zone paging, or other situations where
a temporary matrix connection is
needed rather than a full memory preset recall. The screen below shows input 1 being routed to outputs 1, 2, and 4.
The crosspoint gain is always 0dB. This could be a multi-zone page setup using input 1 as the paging microphone
input.
Mute In / Mute Out - Allows one or
more inputs (Mute In) or outputs (Mute
Out) to be temporarily muted. The first
momentary contact closure on the
programmable input pin will mute the
specified input(s) or output(s), and the
next momentary contact closure will
unmute them. The screen below
shows that programmable input 1 is set
to mute inputs 1, 2, 7, and 8.
