IINNTTRROODDUUCCTTIIOONN
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, lightest, 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.
STEREO PPOWER AAMPLIFIER
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 transparent, 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.
INPUT CCHANNELS
1. MMICROPHONE && LLINE IINPUTS
The MP10DS features standard XLR type Low-impedance MIC IN connectors on the first 6 channels. These microphone inputs are electronically balanced for maximum noise suppression and have characteristics
matching all low impedance dynamic microphones. Condenser microphones may also be connected with 24 Volt DC phantom power activated via the back-panel PHANTOM push-button. (Note: condenser and
dynamic mics may be used together with the PHANTOM power activated. 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 balanced 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).
2. CCHANNEL GGAIN CCONTROLS && CCLIP LLEDS
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.
3. CCHANNEL LLOW, MMID, && HHIGH EEQUALIZATION
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.

As with all equalizers, boosts at one or more frequencies increase the channel’s signal level. If
the channel is already at a fairly high operating level, this may cause clipping, in which case
the CLIP LED will light. Reduce the GAIN setting and/or the EQ boosts if CLIP activity is
excessive. (Note: center position reflects a neutral or flat EQ control setting, however lower
EQ control settings may be effectively employed to reduce feedback and/or distortion).
4. CCHANNEL MMON CCONTROL
Each channel has a MON (monitor send) control which varies the amount of channel signal
being tapped off and sent to the monitor bus in the MP10DS. The MON signal is pre-fader
and pre-EQ, in other words it is taken before the GAIN and EQ controls so that the monitor
mix can be independent of the main mix. As a result, channel EQ settings do
not affect the sound of the monitor signals, nor do the channel GAIN controls
regulate their volume. (Note: with an independent monitor mix, it may be beneficial to connect a graphic equalizer to the MONITOR output for feedback
control).
5. CCHANNEL EEFX CCONTROL
Each channel has an EFX (effects send) control which adjusts the level of the
channel signal being tapped off and sent to the MP10DS, effects bus. This signal is post-fader and post-EQ, in other words it is affected by both the channel
EQ controls and the channel GAIN control. Normally, the output signal from
the effects bus is internally routed to the DIGITAL EFFECTS PROCESSOR. In
this situation, the EFX control would regulate the intensity of the built-in effects
on that channel’s sound through the main PA system and the RECORD OUT
jacks. In standard operating mode with the built-in effects working, you would
connect a regular on-off footswitch (e.g. Yorkville model IFS-1A) to the EFX
FOOTSWITCH/SEND jack to turn the internal effects on and off. See the section EFX FOOTSWITCH/SEND later in this manual for more information.
Alternatively, this signal can be connected to the input of an external stereo
effects unit and returned via channel 7/8 or 9/10. However, if you do not
require any effects at all, the effects bus output signal can be connected to the
input of an additional monitor system or other amp/speaker system via the EFX
FOOTSWITCH/SEND jack using a standard shielded patch cord. In this case,
the EFX controls would act as send controls to achieve a semi-separate mix.
(Remember that the channel GAIN controls will also affect this signal).
6. CCHANNEL PPAN && BBALANCE CCONTROLS
The signal balance of each channel going to the left and right main PA channels
can be adjusted by the PAN control in channels 1 to 6, and by the BALANCE
control in channels 7/8 and 9/10. Turning this control counterclockwise
towards the L will increase the signal level in the left channel while also reduc-
ing the level in the right channel. Turning the control clockwise towards the R will increase the
signal level in the right channel while also reducing the signal level in the left channel. For
stereo PA applications, you would leave the PAN and BALANCE controls at center position.
This ensures that all audience members throughout the venue hear the same mix of instruments
and voices. However, if you are using the MP10DS strictly for recording purposes, you may
employ the PAN or BALANCE controls to send channels or stereo-recorded music tracks to the
left or right tape tracks by turning them all the way to L or R.

MASTER SSECTION
1. MMAIN MMASTER CCONTROL && CCLIP LLED
The MAIN MASTER control adjusts the overall level of the main mix and the PA volume.
Beside this control is a CLIP LED, which indicates high signal levels within the main mixing
bus. Reduce the MAIN MASTER or the channel GAIN controls if the MAIN CLIP LED is more
than slightly active. (Note: to ensure maximum signal headroom and clarity, operate the mixer
with the MAIN MASTER set at 7 or so. This way, you will be running the channel GAIN controls at lower settings, which helps to ensure that the channels do not clip).
2. MMONITOR MMASTER CCONTROL
The overall level of the monitor mix is adjusted with the MONITOR MASTER control. Beside it
is a CLIP LED, which indicates high signal levels within this bus. Reduce the MONITOR MAS-
TER or the channel MON levels if the MONITOR CLIP LED is more than slightly active. (Note:
as with the MAIN MASTER, keep the MONITOR MASTER at a relatively high setting to ensure
maximum clarity).
3. MMAIN EEFFECTS MMASTER CCONTROL
The MAIN EFX master control regulates the amount of signal going from the output of the
internal DIGITAL EFFECTS PROCESSOR to the MAIN mixing bus where it is mixed with the
dry signals direct from the channels. It controls overall effects intensity on the L and R MAIN
output signals and RECORD OUT signals and through the main PA speakers.
4. MMONITOR EEFFECTS MMASTER CCONTROL
The MONITOR EFX master control regulates the amount of signal going from the output of the
internal DIGITAL EFFECTS PROCESSOR to the MONITOR mixing bus where it is mixed with
the dry signals directly from the channel MON send controls. It controls the overall effects
intensity of the MONITOR LINE OUT signal.
5. MMAIN LLINE OOUT && AAMP IIN JJACKS
These jacks can serve a variety of patching and routing purposes. They are positioned in the
signal path after the MP10DS, main graphic equalizer and are therefore regulated by it (i.e.
they are post-EQ).
The main bus signals are available at line level (not speaker level, use the SPEAKER outputs
on the back panel to drive speakers) from the L & R MAIN output jacks. Taking a signal from
these jacks has no effect on the operation of the MP10DS, built-in power amplifier. It is there-
fore possible to feed an external power amplifier or even
several, interconnected power amps, with the MAIN output signals while the internal power amplifier is also
functioning (although it is not necessary to have speakers
connected - e.g. if you want to use the unit strictly as a
mixer). If a mono signal is required, possibly to feed a
mono-house PA or another amp/speaker system, use the L
- MONO jack. Mono operation of this jack is converted
to left channel stereo operation as soon as a jack is insert-
ed in the R MAIN output jack.
The AMP A IN and AMP B IN jacks are direct inputs to
the built-in power amplifier. They are referred to as A and
B rather than left and right simply because, with the
MP10DS, versatile design, it is possible to power main PA
speakers with one amplifier channel, and monitors with
the other. This can be accomplished by running a shielded
patch cord from the L- MONO MAIN output to the AMP
AINjack, then another patch cord from the MONITOR
output to the AMP B IN jack. An alternative use for the
AMP A & B IN jacks is as patching inputs. Because they
are switching jacks, when you plug into one, or both of
them, you interrupt the internal flow of signals going from
the outputs of the Main mixing bus to the inputs of the
built-in power amp. This allows you to insert stereo signal
control devices such as an élite processor, an additional
3

MICROMIX
equalizer, or a compressor/limiter into the Main stereo signal path. This is accomplished by
connecting two cables from the L & R MAIN outputs to the device’s input jacks and two more
cables from the device’s output jacks to the MP10DS, AMP A & B IN jacks.
It is even possible to connect another mixer to the MP10DS, power amplifier via the AMP A
& B IN jacks. This slaves the amplifier to that mixer’s signals (i.e. it no longer receives the
built-in mixer’s signals), which means that you could use the built-in mixer to do another,
totally separate mixing job. For example, you could patch the MP10DS, L & R MAIN outputs
to two inputs on another mixer connected to amps driving a PA speaker system while using
the A and B amps to power control room speakers.
6. RRECORD OOUT JJACKS
These phono connectors carry the Left & Right pre-EQ (not affected by the MAIN EQ) main mix
signals. RECORD OUT signal levels are regulated by the MAIN master. Using phono-to-phono
patch cords, connect the RECORD OUT jacks to the Aux. (line-level) inputs on the tape deck.
Actual recording levels would now be adjusted using the tape deck’s record level control/s.
Best results for recording will be achieved with the MAIN master and channel levels set fairly high. If you need to record while the MP10DS is
operating in a PA situation and set at lower levels,
perhaps in a church, you can have a technician
make up two short **padded patch cables as specified below. These would be connected between
the L & R MAIN LINE OUT jacks and the AMP A &
B IN jacks. They will reduce the amount of signal
going to the power amplifier inputs so that the
MAIN master and channel levels can be set high
enough to provide adequate RECORD OUT signal
levels without the PA system being too loud.
** To fashion the -20dB padded patch cables, start with two short, shielded patch cords. On each
cord, solder a 10k Ohm resistor in series with the tip of the plug to be inserted in a LINE OUT
jack, then solder a 2.2k Ohm resistor across the plug to be inserted in an AMP IN jack. It would
then be advisable to identify either the LINE OUT or AMP IN plugs on both cords perhaps with
tape or a dab of paint on the plug jacket.
7. MMONITOR LLINE OOUT JJACK
The monitor bus output signal is available at line level (not speaker level) from the MON OUT
jack and would normally be patched to the input of a mono power amplifier, or one channel
of a stereo amp driving monitor speakers. Keeping in mind that there is no internal equalization for the monitor mix, you might want to patch a graphic equalizer between the MONITOR
OUT jack and the input of your monitor power amplifier to help regulate feedback (see Note
below). As mentioned under MAIN OUT & AMP IN JACKS, the monitor mix signal can also
be patched to one channel of the internal amplifier. If a main/monitor amplifier configuration
is desired, use the LEFT MONO signal from the MAIN OUT jacks to feed one amplifier. The
MON OUT signal could be used to feed the remaining amplifier (this is also covered in the
previous section).
Note: Patching something between things, in this case, means connecting the MP10DS ’s MONITOR
OUT jack to the input of an EQ and the output of the EQ to the input of a monitor power amp
8. EEFX FFOOTSWITCH/SEND JJACK
This jack may be used to connect a standard on/off footswitch for the internal DIGITAL
EFFECTS PROCESSOR or alternately as an effects send jack to another effects processor. In this
latter function, both devices would be sent signal. In that instance, you could connect the
external unit’s left and right outputs to the L & R inputs on channel 7/8 or channel 9/10 (or
any of the other channels. Here you would need to keep the GAIN level of that channel fairly
low and make sure that its EFX control is turned off on these channels. As another alternative,
the EFX FOOTSWITCH/SEND jack may be used to deliver line-level signal to the input of an
auxiliary amp/speaker system or a tape deck. Here, the channel EFX controls would act as secondary level controls. Keep in mind, however, this means that the built-in DIGITAL EFFECTS
PROCESSOR will be disabled.
