MX 2322
MX2322 is another product realized due to increasing demand that requires more flexible mixers that is both
suitable for PA system ( PAVA ) as well as for applications in conference room, classrooms, small function halls
etc.
It allows easy assignment for inputs to outputs or both by selecting the required switch. Mic pre-amps is available
for better input controls through input source balancing. Individual output shall has its own tone controls, either
to suit the speaker delivery area or different types of speakers used.
Please read through the manual before installation in order to capture the features available and how to suit your
applications. We assure you that you are getting a reliable product for usage in years to come.

Note on Applications :
The above sample is suitable for Mosques or similar applications that may utilise different types of speakers that
requires some audio equalisation to suit the speakers' characteristics or the environment.
All inputs shall be routed to both A and B outputs that goes to different amplifiers that cater for specific speakers
eg. Output A to amplifier A for Horn and Ouput B to amplifier B for Hall speakers. Speaker zone selector is an
option in case there is to need to turn On or Off certain zone.
Each individual output channel can be tuned with the 3 band tone controls to suit the speakers used. ie. you may
need to decrease the bass for horn speakers.

Note on Applications :
Above illustration is suitable for general paging as well as Uninterrupted Paging setup ( use ZS5602 ).
Among application that requires above illustrations :
- System that requires 2 sets of music for different zones
- Uninterrupted paging, which paging one zone would not affect another
- Normal and Emergency zones, which emergency zones would only require paging audio, otherwise in silent
mode
Consult us if you need to expand the system to include other equipments such as line supervisory, changeover
etc.

Paging mic can be powered directly from MX2322.
Therefore external adaptor at paging mic shall not be
needed.
Phantom power of 18V is available for source that
requires this ie. Condensor Mic push the switch down
to turn on the Phantom power. If source does not
require this, we recommend this switch is pushed to Off
position ( upwards )
Select the input level type for Ch.1 to 8 using
the slide switch accordingly
Priority line input is available for source such as tone generator or
message player or emergency mic. To activate the priority feature, the
front priority switch must be switched ON.
Priority Switch is available for Ch1, 11 and 12. It shall mute all
other channels and shall resume after approximately 5 seconds.
Muting shall occur at both Output A and B.

AMPERES MX2322 DUAL BUS PRE-AMPLIFIER MIXER
INPUT ROUTING SWITCHES A & B
Press the required switch to send input source to either A or B, or both.
TONE CONTROL CH A
TONE CONTROL CH B
MAIN OUTPUT CONTROLS
1. EQUALISING INPUT LEVEL OF DIFFERENT AUDIO SOURCE
Output levels from different audio source may be different, such as microhones which could be at -40dBu, whereas
instruments at 0dBu or 0dBv and some audio players could be more than 4dBU ( 1.22 V rms ). Before reaching the
individual volume controllers, these input sources should be adjusted at "Pre-Input Volume Control " level to
enable easier controls. They can be either increased or decreased, ranging from -6dB to +3.5dB.
2. ROUTING INPUT SIGNAL TO OUTPUT CHANNEL
Input channel can be routed by pressing the A or B button. If it is required to send to both outputs, press both A and
B.
3. MIXED OUTPUT TONE CONTROLS
Each output ( A and B ) has 3 band tone controls with Low at 100 Hz, Mid at 1 kHz and High at 10 kHz. Each band
has shelving of +15 to -15 dB gain.
See diagram on the tone controls.
4. MAIN VOLUME CONTROLS
Each output has mixed signal main volume control and the levels are indicated by signal LED. To avoid audio clipping
which may distort the sound, ensure it is always within 0dB, which is approximately 1.22V rms.
3 BAND TONE CONTROLS
Adjust tone controls as per desired listening
preference or to suit different types of speakers.
PRE-INPUT VOLUME CONTROL
Adjust the input signal with gain or attenuation according to input source to reach equal level as
compared to other sources. Ensure the Clip indicator does not lit.
CHANNEL VOLUME CONTROL
Adjust these according to the required mixing level with other sources. Audio intensity is indicated
by Signal LED

AMPERES MX2322 DUAL BUS PRE-AMPLIFIER MIXER
3 tones band control with cut off frequencies at 100Hz ( Low ), 1 kHz ( Mid ) and 10 kHz ( Hi ) is available for simple
output tuning to fit listening preference or to drive certain speakers such as sub woofer or horn speakers.
As mixed audio may have rather low frequency level, adjusting upwards the gain of Low tone knob may increase
the bass delivery. Using horn speaker may be the opposite as low frequencies may need to be attenuated to protect the
horn coils.
Adjustment of tones may need certain skill to deliver optimum audio delivery or to prevent echo or feedback in installa-
tions. For more refined tuning, 31 band graphic equaliser be useful. Please consult qualified audio technician for refined
tuning.
