APPLICATION SAMPLES
1. Application as a mixer
When the mono channels are operated in MIX mode, a maximum of 8 (6+2) mono input
signals can be summed and routed to the main outputs. In this mode, the individual signal
sources are connected to the mono inputs on the MX-880. Each channel has a LEVEL knob
to control the amount of its signal relative to others in the main section. Via the
corresponding PAN control, each mono input signal can be routed either to the left or right
main output, also any intermediate PAN settings can be achieved as well. The MAIN
OUTPUT LEVEL control determines the overall level of the main output signal. Since the
two main inputs are alternatively routable to the main outputs, two additional input signals
can be added using the main inputs. For this you have to depress the MAIN LINK switch.
However, as these inputs do not feature a PAN control, the left main input will always be
routed to the left main output; similarly, the right main input can only be sent to the right
main output. A total of 8 mono channels can thus be routed to two main outputs.
2. Application as a splitter
A splitter is a distribution amplifier which allows for splitting a specific input signal to several
outputs. This function is of use, e.g. in a large-scale sound reinforcement system where the
mixer's output signal needs to be allocated to several power amplifiers. Another field of
application is in tape duplication systems, where one master tape machine is to be
interfaced with several tape duplication recorders.
In this mode, the output signal from the mixer is applied to the main inputs of the MX-880. If
the SPLIT/MIX switches are set to “SPLIT”, the mono outputs of the respective channels
provide either the left or the right main signal. Depending on the setting of the BALANCE
control, any balance between left and right main signal can be adjusted.
At the same time, the main input signal is also sent to the left or right main output, so that
here two additional splitter outputs are available. Please note that these outputs do not
feature a balance routing function. The left main input is routed exclusively to the left main
output; similarly, the right main input feeds the right main output only.
3. Application as a 4-channel stereo splitter
For this special application, the splitter function configures the unit as a 4-channel stereo
splitter. Here, the stereo signal source is connected to the two main inputs. If all mono
channels are operated in SPLIT mode, the BALANCE controls of channels 1, 3, and 5 are
set to “LEFT”, and the BALANCE controls of channels 2, 4, and 6 to “RIGHT”; thus, the
corresponding stereo output pairs are routed through channels 1+2, 3+4, and 5+6. This kind
of application is particularly useful for tape duplication systems.
4. Application as a matching amplifier
The MX-880 can also be used as a multiple matching amplifier. The task of a matching
amplifier is to convert the level of a signal source into another level. For instance, a cassette
recorder with home recording level (-10dBV) can be raised to studio level (+4dBu).
Of course, this process can also be reversed (level attenuation).
In this application, the MX-880 is operated in MIX mode. The output of the signal source is
connected to the mono input of the MX-880. The corresponding mono output provides the
resulting output signal which can be raised or lower in level. Each of the six mono channels
is equipped with a LEVEL control. The control range is from -
∞
(full attenuation) to a
maximum gain of +15dB.
