MA2120 Setup Guide
Connect a microphone, BGM tuner, CD player or other portable audio player to an [INPUT] connector/jack using an appropriate cable
when the device is powered off. After finishing all connections, connect the power cord to an AC outlet.
Warning
When connecting the power cord to an AC outlet, an input signal will turn on the power of this device by the auto-wake function. To avoid
unexpected loud sounds, be sure to connect microphones and external devices with the power off status.
NOTE
Refer to “Attaching Euroblock Plugs” for Euroblock plug installation.
 Connecting Microphones
Connect microphones to [INPUT] connectors 1 - 6 using a
Euroblock plug.
When using a microphone that requires phantom power (+24V),
set the [GAIN] switch to “MIC(+24V)”.
For microphones that do not require phantom power, set the
[GAIN] switch to “MIC”.
Caution
• Only switch the phantom power on/off when the [VOLUME A]
and [VOLUME B] knobs are turned all the way down.
• Keep the phantom power turned off when it is not required, or
if you wish to connect a non-supporting device.
• Do not connect or disconnect the cable while phantom power
is left on.
 Connecting External Devices
Use the following procedure to connect a line level external
device.
Use a Euroblock plug to connect via [INPUT] connectors 1 - 6.
At this time, set the [GAIN] switch to “LINE”.
If the external device has an extremely low output level, set the
[GAIN] switch to “MIC” to improve the input gain.
Use an RCA cable to connect to [INPUT] jacks 7 and 8. If the
source is stereo and you are using zone A and zone B as stereo,
set the [MODE] switch to “STEREO”. If you are using zone A and
zone B separate from each other, set the [MODE] switch to
“MONO” and use the [ROUTE] switch to select which zone
receives the audio output.
Use a mini-stereo plug to connect via the [AUX IN] jack on the
front panel. The signal from the [AUX IN] jack is mixed into the
same signal path as [INPUT] jack 8.
 Using the Mono Sum Input
[INPUT 5] and [INPUT 6] are equipped with mono sum input.
Each can be used for summing a line level stereo source, or two
separate mono sources. The input signal is mixed directly to
mono and output to the zone that was selected using the
[ROUTE] switch for [INPUT] jack 5 and 6. Use of the [MONO
SUM INPUT] jacks can allow a large number of external devices
to be connected without the need for a separate mixer. However,
note that when there is also input via Euroblock plugs for
[INPUT] connector 5 or 6, the signal input from [MONO SUM
INPUT] is mixed in with the signal from [INPUT] connector 5 or 6.
