SECTION 1
OPERATION
1-
1. GENERAL
The Sony MXP-29 has been designed to be multi-
purpose audio mixer capable of performing all the
essential functions required for apublic address system,
radio and TV broadcasting, studio recording and tape
editing. The compact and lightweight design demon-
strates its ability especially outdoors for relay broad-
casting. It can also be controlled by avideo editing
control unit so that the video and audio signals can be
edited simultaneously.
8channel inputs with various adjustment possibil-
ities
Each input can be independently adjusted to suit the
connected equipment and to provide excellent mixing
results from its own low-cut filter and equalization
circuits.
With the PAN POT(panoramic potentiometer) function,
each input sound image can be positioned to the
desired spot between the Land Rstereo output
channels.
Auxiliary inputs and outputs for additional mixing
effects
By connecting an echo machine or areverberation
unit, additionally desired sound effects may be easily
obtained.
One of the outputs can be used to supply signals to a
fold-back speaker for players on the stage.
Monitoring of various signals
Each line and auxiliary output signal can be monitored
either with headphones or speakers for accurate
mixing. In addition, the PFL (pre-fader listening) function
permits direct monitoring of each of the original incoming
signals.
Control with an external equipment
In combination with an editing control unit such as a
BVE-900, the output level of each channel can be
controlled. So the audio signal can be edited in
synchronization with avideo signal.
Power supply circuits for condenser microphones
The built-in power supply circuits can supply the
required power of 48V DC to connected microphones.
2-
way powering
The MXP-29 can be operated either on AC power or on
12V DC.
Easy rack mounting
The table-top design can be easily converted for rack-
mounting in a19-inch standard rack
