FRONT PANEL

The MX-880 has six identical channels, each one is equipped with 2 rotary controls,

1 button and 8 LED indicators, also the same on the main control section (in/out),

please see details as below:

1. POWER: Press this button to turn the MX-880 on and off.

2. MAIN INPUT LEVEL: The main input level control sets the main input gain, before the

signal reaches the input bus. In SPLIT mode, the MAIN INPUT LEVEL control determines

the common output level for all mono outputs.

3. INPUT LEVEL: From this 4-digit input level meter is allowed to know the input level of the

main input within a range from -24dB to +6dB.

4. MAIN LINK: While press this main link switch you can route the MAIN INPUT signal to

the MAIN OUTPUT. This way it is possible to route a maximum of 8 input channels to the

main mix.

5. MAIN OUTPUT LEVEL: The main output level control adjusts the output level applied to

the main outputs. The levels present at the 6 mono outputs are not affected. Summing the

signal levels of several mono channels can overload the main output stage. The MAIN

OUTPUT LEVEL control is therefore used to adjust the overall output level.

6. OUTPUT LEVEL: From this 4-digit output level meter is allowed to know the output level

of the main input within a range from -24dB to +6dB.

7. SPLIT/MIX: This switch sets the respective channel to SPLITTER or MIXER mode.

8. LEVEL: The level control determines the signal level of the individual channels. In SPLIT

mode, the LEVEL control sets the output level of the mono channels. In MIX mode,it

controls the amount of the mono channel's input signal feeding into the main output

section; at the same time, the level of the mono channel can be determined, the

maximum gain is +15dB which allows for mode converting.

9. INPUT/OUTPUT LEVEL: In SPLIT mode, this 8-digit output level meter is allowed to

know the output level of each channel within a range from -24dB to +18dB; In MIX mode,

it shows the input level of each channel within the same range.

10. BALANCE/PAN: This control sets the balance between the left and right main signals. In

SPLIT mode, the main input signal is routed to the mono output, with the balance control

determining the balance between the left and right main signal portions. In MIX mode, the

mono inputs are mixed and routed via the level control to the main outputs, with the PAN

controls determining the allocation of the mono inputs to the left and right main outputs.

OPERATION

MAIN Section

Both main inputs interface via the main input level control with the input bus as well as with

the main outputs. The main output level control determines the output level of the signals

which are summed by the second bus (i.e. the output bus) and are subsequently routed to

the main outputs.

SPLIT Mode

In SPLIT mode, the main input signal is sent via the balance control to the output buffer

amplifiers of the mono channels, with the level control determining the output level of the

respective channel. The maximum gain is +15dB.

MIX Mode

In MIX mode, the input signals of the mono channels are “collected” via the LEVEL and PAN

controls and are routed to the output bus. In this mode, the LEVEL control determines the

amount of each channel at the output bus, while the PAN control is responsible for the

allocation of the input signal to the left and right main outputs.

Additionally, the input signal is routed to the respective mono outputs, i.e. the circuit acts as

a matching amplifier. The LEVEL control allows for level compensation of up to +15dB.

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.
