Introduction
For the variety level signal input
and the convenience of usage, the
MONO input channel has a MIC input
socket, a LINE input socket and a input
level attenuation switch. Every channel
has HI, MID, LOW equalization circuit,
AUX output and EFF send. There is a
7-band graphic equalizer for the LEFT
& RIGHT outputs to embellish the
timbre. And the b
. The
unit also has a stereo playback input
channel.
Besides stereo PA output , this
series mixer also has, mixing output,
AUX outputs and record outputs.
Furthermore, you can use headphone
to monitor, headphone volume can be
adjusted separately.
The built-in power amplifier has
manifold protectors and uses air cooling
for heat emission.
This series mixer has consummate
functions and perfect shape.
Thank you for purchasing the MP-D
series powered mixer, it have two
varieties in this series, they are MP-8D
and MP-12D. MP-8D has 4 mono input
channels and 2 stereo input channels, it
can provide output power 2X175 watts
for 8 ohms load or 2X300 watts for 4
ohms load; MP-12D has 8 mono input
channels and 2 stereo input channels, It
can provide output power 2X300 watts
for 8 ohms load or 2X500 watts for 4
ohms load. They are excellent power
mixer suitable for a wide variety of input
sources.

Precautions
Location
Keep the unit away from locations where it
is likely to be exposed to high
temperatures or humidity - such as near
radiators, stoves, etc. Also avoid locations
are subject to excessive dust accumulation
or vibration which could cause mechanical
damage and locations subject to strong
electromagnetic fields, such as close to
broadcast equipment.
1.
Ventilation
The unit has ventilation slots on the side
panel and bottom panel.
Do not block these vents.
2.
Avoid physical shocks
Strong physical shocks to the unit can
cause damage.
Handle it with care.
3.
Do not open the case or attempt repairs
or modifications yourself
This product contains no user - serviceable
parts. Refer all repair or maintenance to
qualified engineer.
4.
Always power off before making
connections
Always turn the power off before
connecting or disconnecting cables.
This is important to prevent damage to
the unit itself as well as other connected
equipment.
5.
Handle cables carefully
Always plug and unplug cables -
including the AC power cord - by
gripping the connector, not the cord.
6.
Clean with a soft dry cloth
Never use solvents such as benzine or
thinner to clean the unit. Wipe clean
with a soft, dry cloth.
7.
Always use the correct power supply
Make sure that the power supply
voltage specified on the rear panel
matches your local AC mains supply.
Also make sure that the AC mains
supply can deliver more than enough
current to handle all equipment used in
your system.
8.

This knob is used for control feed
to the EFF bus, it has been set after the channel
fader, so it is enslaved to the fader position.
Adjust this knob when you use effector on this
channel.

PAN control
11
This konb is used for distributing the signal level
of the channel feed to L/R buses. They are equal
which are feed to bus when the knob locates in
the middle .
Channel "ON" switch
12
When turn the switch "ON" signal of the channel
will be sent to stereo L/R bus , AUX and EFF
buses.
When turn the switch "OFF" the output signal to
each bus will be muted completely. The switch
should be turned off for unused channels.
PFL switch(input channel)
13
This switch allows you to monitor the signal of the
input channel at the pre fader level. You can use
headphones to conveniently check the input signal
of a specific channel, or trouble-shoot a channel
that is having problems.
Channel fader
14
This fader is used for controlling the channel signal
level feed to the L/R buses, It can be adjusted for
level balance between channels. It should be pulled
down when the channel is not in use.
PHANTOM +48V
phantom power switch and indicator
This button switch is used for turning on or off the
+48V phantom power in the unit. The +48V phantom
power will exist on the input socket of four
corresponding microphone input channel when this
switch is pressed.
Notices: Slide down all channel fader before turning
on or off the switch;
Don't plug or unplug microphone after this
switch were turned on;
Don't turn on the phantom switch when a
dynamic microphone is in use.
