Introduction
Thank you for purchasing a Yorkville powered mixer. We at Yorkville Sound are confident that you’ll find the M608 to be an excellent and versatile mixer/amp. We’ve
used our experience in the development of powered mixers to create the smallest,
lightest, and most powerful combination mixer/amplifiers available. This manual
contains information to help you get the maximum performance from your M608. We
hope you’ll take the time to read it.
Stereo Power Amplifier
The M608 features high-efficiency stereo power amplifiers that have been designed to deliver maximum power into 4 to 8 ohm loads. When lower speaker impedances are connected,
a dedicated, sonically transparent circuit limits the output power to safe levels. Multiple
speakers may be connected without the amplifier overheating or shutting down.
Input Channels
14
1. MIC and LINE Inputs
The M608 features gold-plated, dual-contact
XLR low-impedance microphone connectors on
the channels. These microphone inputs are balanced for maximum noise suppression. Condenser
microphones can also be connected. The 48 Volt
DC phantom power is activated by depressing the
Phantom Power push-button on the rear panel.
Note: Condenser and dynamic mics can be used together while the phantom
power is on. It will not affect the performance of the dynamic mics.

In addition to the XLR inputs, each channel features ¼-inch LINE in jacks. Channels
1-2, 5/6 and 7/8 are balanced line-level inputs and will accept either balanced (Tip/
Ring/Sleeve) or unbalanced (Tip/Sleeve) input cables from high impedance microphones,
mixer line outputs, keyboards, synthesizers, electric pianos etc.
Note: When connecting a balanced signal, use balanced patch cables with either an
XLR or a Tip/Ring/Sleeve ¼-inch plug on the mixer end.
Channels 3 and 4 have very high impedance, unbalanced ¼-inch inputs which are optimized for instruments such as electric basses, acoustic electric guitars etc. Stereo channels 5/6 and 7/8 have left and right ¼-inch balanced LINE in jacks as well as mono gold-
plated XLR low impedance microphone inputs. The ¼-inch inputs may be used to connect
a stereo CD player, tape deck or an additional mixer etc. A phono pre-amplifier must be
connected to the M608 inputs for optimum turntable performance.
Connecting signals to both types of inputs on any one channel (MIC and LINE in) is
not recommended. To do so may change the gain 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 and Pan appropriately or sum to
mono using a ‘Y’ cable.
2. Channel GAIN Controls and CLIP LEDs
1
This adjustment determines the signal level sent to the MAIN mixing bus. The CLIP LED
will illuminate when the channel’s overall signal level is 3 dB below the onset of actual
clipping. As a result, small amounts of clip 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 M608 has 5 busses: MAIN (left and
right), MONITOR, EFFECTS and RECORD OUT.
3. Channel Lo, Mid, and Hi Equalization
The M608 tone controls adjust the bass, middle and treble frequencies for each channel
independently. Center frequencies have been carefully selected to help achieve the best
quality of sound. Bass is centered on 40 Hz, Mid at 700 Hz and the Hi is at 12 kHz. The
adjustment range for each control is +/- 15 dB. These parameters provide versatile equal-
6
7
91
ization consistent with the clean simplicity of the M608’s design. As with equalizers,
boosting one or more frequencies increase the channel’s level. If the channel is already at
a high level, clipping may occur, in which case the clip LED will illuminate. Reduce the
GAIN setting and/or the Equalizer if clip activity is excessive.
Note: The center position reflects a neutral or flat EQ control setting; however, turning down EQ settings can be used effectively to reduce feedback and/or distortion).

4. Channel MON Controls
The MON control (monitor send) on each channel varies the amount of signal being
sent to the monitor bus in the M608. In the mono channels the MON signal is pre-
GAIN control and pre-EQ. It is taken before the GAIN control so the monitor signal can
be mixed independently of the MAIN mix. As a result, channel EQ and GAIN settings
do not affect the sound of the monitor signals. The MON signal in the stereo channels
is also pre-GAIN and pre-EQ.
Note: With an independent monitor mix, it may be beneficial to connect a graphic
equalizer between the MON output and the monitor amplifier (Power AMP IN B,
external amplifier or powered speakers, depending on how you have it set up) to
help control feedback.
5. Channel EFX Controls
The EFX control (effects send) for each channel adjusts the level of the channel signal
being sent to the M608 effects bus. This signal is post-GAIN control and post-EQ, the
sound is affected by both the channel EQ controls and the channel GAIN control. The sig-
nal from the effects bus is internally routed to the Digital Effects Processor. The channel
EFX control regulates the intensity of the built-in digital effects for the channel’s output.
When using the built-in digital effects, you can connect a standard on/off footswitch (e.g.
Yorkville model AFS1) to the EFX Out/Footswitch jack to turn the internal effects on or off.
For more information see the section EFX Out/Footswitch in this manual.
MICROMI
X
Tip: Alternatively, this signal at this jack can be connected to the input of an exter-
28
28
nal stereo effects unit and returned via channel 5/6 or 7/8 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 another amp/speaker system via the EFX
Out/Footswitch jack using a standard balanced 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 also affect this signal.
6. Channel Pan and Bal Controls
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 4, and by the Bal control in channels 5/6
and 7/8. Turning this control counterclockwise towards the L will increase the signal level
in the left channel to a maximum of 3 dB while also reducing the GAIN in the right channel to zero. Turning the control clockwise towards the R will increase the signal GAIN in
the right channel while also reducing the signal GAIN in the left channel.
Master Section
1. MAIN Master Control
The MAIN master control adjusts the overall level of the main
mix, the PA volume.
Note: To ensure maximum signal headroom and clarity, set
the channel GAIN controls first for a good signal without clipping, then set the master for the overall volume desired.
2. MON Master Control
The overall level of the monitor mix is adjusted with the MON
master control.
Note: As with the MAIN master, set the MON
master to deliver the desired volume after setting the channel sends.

5. Post-EQ OUT
These jacks offer a variety of patching and routing options. They are positioned in the
signal path after the M608 main graphic equalizers.
These bus signals are at line level, not speaker level (use the SPEAKER outputs on
the rear panel to drive speakers). Using signals from these jacks has no effect on the
operation of the M608's built-in power amplifier. This makes it possible to feed an
external power amplifier, or even multiple inter-connected power amps, while the internal power amplifier is functioning.
Note: It is not necessary to have speakers connected if you’d like 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 Post-EQ jack. Mono operation of this
jack is switched to left channel only as soon as a jack is inserted in the L Post-EQ
jack. They follow the operation of the Main/Mon switch described below.

6. Power AMP IN Jacks
The Power AMP A IN and Power AMP B IN jacks
are direct inputs to the built-in power amplifiers.
They are referred to as A and B rather than left
and right simply because it is possible to power
both main PA speakers with one amplifier channel
and monitors with the other. This can be accomplished by selecting the Main/Mon position on
the selector switch located between the graphic
equalizers. In the Left/Right position, Power AMP A receives the left signal while Power
AMP B receives the right signal. In the Main/Mon position, Power AMP A receives a mono
sum of left and right signals while Power AMP B receives the monitor signal. An alternative
use for the Power AMP A IN and Power AMP B IN jacks would be as patching inputs. Since
they’re switching jacks if you plug into one (or both) the internal signal flow will be interrupted. This interrupts the signal from the M608 mixer to the built-in power amplifiers allowing you to insert signal control devices such as an élite processor, an additional equalizer,
or a compressor/limiter into the main stereo signal path. Connect cables from the L and R
Post-EQ OUT to the device’s input jacks and then from the device’s output jacks to the M608
Power AMP A IN and Power AMP B IN jacks.
You can connect another mixer to the M608 power amplifier through the Power AMP A IN
and Power AMP B IN jacks. This slaves the amplifier to the other mixer’s signals; it no longer
receives the built-in mixer’s signals which means that you could use the built-in mixer to do a
totally separate mixing job. For example, you could patch the M608 L and R Post-EQ OUT to
inputs on another mixer connected to other amplifiers driving a PA speaker system while using
the M608’s A and B amps to power control room speakers.
Power AMP IN
7. Rec OUT Jacks
These phono connectors send the L and R pre-EQ, pre-EFFECTS (not affected by the
MAIN EQ) main mix signals. The Rec OUT control adjusts the signal level for these
jacks. Using phono patch cords, connect directly to the Auxiliary (line-level) inputs on a
tape deck or other recording device.
8. MON Out Jack
The monitor bus output signal from the Mon OUT jack is line level
and would normally be patched to the input of a mono power amplifier (or a single channel of a stereo amp) driving stage monitor speakers. Keep in mind that in the Left/Right position of the Amp Assign
switch there is no internal equalization for the monitor mix (you
might want to patch a graphic equalizer between the Mon OUT jack
and the input of your monitor power amplifier, this can help regulate
the feed). As mentioned under #4. Post-EQ OUT section (above), the
monitor mix signal can also be patched to one channel of the internal
amplifier using the Amp Assign switch.
MON OUT
9. EFX Out / Footswitch Jack
Using this jack you can connect a standard on/off footswitch to
control the activation of the internal Digital Effects Processor or
it can be used as an effects send jack for use with an external
effects processor.
Note: Both devices would be sent a signal, so you could connect the external unit’s
left and right outputs to the L and R inputs on channel 5/6 (channel 7/8 or any of
the other channels). Use the GAIN of that channel to adjust the amount of wet
signal added to the main mix and the MON control to adjust the amount of wet signal added to the monitor mix. Make sure that its EFX control on the channels are
turned off. An alternative would be to use the EFX Out / Footswitch jack to deliver
line level signal to the input of an auxiliary amplifier or even a recording device.
Here, the channel EFX controls would act as secondary level controls.

10. Power LED and Switch
The Power LED lets you know that the M608 is plugged in, turned on and all systems
are normal. The AC power on/off switch is on the rear panel of the M608.
11. Phantom Power
The Phantom Power LED indicates that 48 volts of DC phantom power is present on
the XLR microphone inputs for powering condenser microphones. Regular dynamic mics
may also be used while the Phantom Power is on. Connecting a microphone of either
type with phantom power on and the channel GAIN up will create a large transient,
resulting in a loud, potentially damaging pop. When setting up, either turn off the AC

button is located on the rear panel between the speaker output jacks.

12. Tape/CD Input
Left and right RCA inputs are provided to connect a CD player, cassette player or other
stereo source to the mixer. These inputs are routed directly to the main bus, the Tape/CD
control adjusts the amount of signal.
13. Mute 1-6 Switch
The M608 includes a feature that enables users to instantly mute channels 1-6. Depressing
the Mute 1-6 switch will mute channels 1-6 signals being sent to the Left, Right, Mon and
EFX busses (the signals from these channels will still be sent to the record bus and will not
be muted. Channel 7/8 will remain active, leaving this channel open for allowing a microphone or CD player, cassette player or other stereo source to be heard over the Left, Right,
Mon and EFX busses. This feature lets you mute the mics and instruments on stage and
still allows you to make announcements or play music during breaks. When the band returns
to perform, simply disable the mute.
Note: The Tape/CD input in the master section also remains active. While muted, the
Mute LED flashes at a slow rate (long on/short off) and the clip LEDs of all the muted
channels alternate long off/short on.
14. Amp Assign Switch
The MAIN controls determine the level of the signal routed through the Amp Assign switch:
i. In the Left/Right position, the Amp Assign switch directs the left and right MAIN
master signals through Equalizer A and Equalizer B. The signal goes to the left
and right inputs of the built-in power amplifier (Amp A and Amp B) and to the
left and right post-EQ OUT jacks.
ii. In the Main/Mon position, the Amp Assign switch sums the left and right
MAIN signals into a single, mono signal while directing it to the input of
Equalizer A, the output of which goes to both the Amp A power amp channel
and to the Post-EQ MAIN OUT jack. Additionally, the signal from the MON mas-
ter’s output is routed through Equalizer B and then to both the Amp B power
amp channel and to the MON Out jack.
Digital Effects Processor
1. Select and MODIFY EFX Controls
Use the EFX Selection control to choose from the
sixteen 24-bit digital reverbs, delays and other
effects. This control rotates continuously, which lets
you rotate clockwise or counter-clockwise to select
the desired effect. For convenience, a table of the
effects and their variables appear later in this manual and on the front panel of the M608.
Parameters for each of the effects can be changed using the MODIFY control which is
located next to the Selection control. For example, if a Hall reverb has been selected,
the MODIFY control will let you adjust the decay parameter. Choosing the Chorus effect
allows the chorus rate to be adjusted.

Note: The signal sent from the internal Digital Effects Processor to the MON mix is
independent from the MON send controls on the channel strips. When a channel’s
EFX control routes a signal to the internal Effects processor and the MON level control (for that channel) is turned off, the channel’s wet effects will still be audible in the
monitor bus (if the EFX to MONitor return level is turned up).
2. Effects CLIP LED
Situated to the right of the MODIFY EFX control, the CLIP LED indicates that the digital processor is receiving an input signal that’s too strong, resulting in distortion. For
optimum performance, the CLIP LED should never flash. If there is clipping activity, turn
down the channel EFX controls appropriately.
Built in 9-Band Graphic Equalizer & Shelving EQs
1. General
Each EQ consists of a set of +/-15dB range type controls. In the M608 there are nine
sliders for each channel, each one operating over a 2/3-octave portion of the midrange
band of sound frequencies, as well as rotary shelving Bass and Treble controls.
Note: Equalizers have an effect on the gain of the main system as well as its frequency response. Once adjusted, you may need to adjust the MAIN master level if
the clip LEDs become too active.

2. Main Functions for the Graphic EQ and Shelving Equalizers
i. To adjust the system to help reduce feedback, a normal technique is to turn the
main system up to the point of feedback and then adjust the EQ sliders individually to determine which frequency band will reduce the potential of feedback.
When the specific frequency band is isolated, set it to about -3 to -5 dB. Usually
only 2 or 3 bands can be reduced before the feedback reduction process begins
to affect the sound quality.
