We have coupled our extensive experience in the development and production of powered
mixers, (with state of the art, computer assisted design technology) to create the smallest, light-
est, and most powerful combination mixer/amplifiers available. We at
Yorkville Sound
are
confident that you will find your new
MP10DS
to be an efficient and versatile solution to your
mixer needs. This manual contains information to help you get the maximum performance
from your
MP10DS
. We hope you’ll take the time to read it.

POWER A
AMPLIFIER
The
MP10DS
features a
high-performance
stereo
power amplifier, which has been designed to
operate safely into low overall speaker impedances. Thanks to a dedicated, sonically transpar-
ent, limiter circuit that adjusts the output power level to keep the circuitry cool. Multiple
speakers may be connected to the amplifier without the amplifier overheating or shutting
down. It will simply reduce output power to a safe level. Just make sure the total load
does not
fall below 4-Ohms.

LINE IINPUTS
The
MP10DS
features standard XLR type Low-impedance
MIC IN
con-
nectors on the first
6
channels. These microphone inputs are electroni-
cally balanced for maximum noise suppression and have characteristics
matching all low impedance dynamic microphones. Condenser micro-
phones may also be connected with 24 Volt DC
phantom
power activat-
ed via the back-panel
PHANTOM
push-button. (
Note:
condenser and
dynamic mics may be used together with the
PHANTOM
power activat-
ed. It will not affect the performance of the dynamic mics). Additionally,
there are high-impedance 1/4”
BAL LINE IN
jacks on all channels. These
are electronically balanced line-level inputs, but will accept either bal-
anced or unbalanced input cables from high impedance microphones,
guitars, amplifier
Line
outputs, synthesizers, electric pianos, etc. (
Note:
when connecting a balanced signal, employ balanced patch cables with
a ring/tip/sleeve (stereo) 1/4” plug on the mixer end). Channels
7/8
and
9/10
have
Left & Right
1/4”
BAL LINE IN
jacks plus
Left & Right
TAPE/CD/LINE RCA
type inputs. Either the 1/4” or
RCA
type input (
not
both) may be used to connect a stereo tape deck, CD player or outboard
mixer to these channels. A phono preamplifier must be connected to the
MP10DS
inputs for optimum turntable performance.
Do not connect signals to both types of inputs on any one channel (e.g. the
MIC and LINE IN’s on channels 1 to 6 or the 1/4” and RCA type TAPE/CD/LINE
IN’s on channels 7/8 and 9/10). To do so will cause improper operation of the
input circuit. (Note: you may connect a stereo source to channels 1 through 6
but you must use two channels, one for left and one for right).

LEDS
The
GAIN
control has a range of
40dB
. This adjustment determines both
the input sensitivity of the channel and the signal level sent to the
MAIN
mixing
bus*
. (The
MP10DS
channel circuitry does not require separate gain
and level controls). The
CLIP LED
is set to illuminate when the channel’s
overall signal level is 3dB below the onset of actual clipping distortion. As a
result, small amounts of
LED
activity are acceptable, however frequent or
continuous activity indicates the need to turn down the
GAIN
control.
In audio terminology, a bus is a mix-down channel where all the signals
from the input channels are blended into one signal. The MP10DS has
three buses, MAIN, MONITOR and EFFECTS.

EQUALIZATION
The
MP10DS
, LOW, MID & HIGH EQ
controls independently adjust the
bass
,
middle
and
treble
frequencies for each channel. Center frequencies
have been carefully selected for optimum sonic adjustments and the gain
range for each control is plus or minus (
+/-
)
15dB
to provide versatile
equalization consistent with the clean simplicity of the
MP10DS
’design.
