Introduction

Thank you for purchasing a Yorkville powered mixer. We at Yorkville Sound are confident

that you’ll find the M810/M1610 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 con-

tains information to help you get the maximum performance from your M810/M1610.

We hope you’ll take the time to read it.

Stereo Power Amplifier

The M810/M1610 features high-efficiency stereo power amplifiers which have been

designed to deliver maximum power into a 4-ohm load. 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

1. MIC and LINE Inputs

The M810/M1610 features gold-plated dual-

contact XLR low-impedance microphone connectors

on the channels. These microphone inputs are bal-

anced 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

1-4, 7/8 and 9/10 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 5 and 6 have very high impedance, unbalanced ¼-inch inputs which are opti-

mized for instruments such as electric basses, acoustic electric guitars etc. Stereo chan-

nels 7/8 and 9/10 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 M810/M1610 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 1-6 TRIM Controls and SET LEDs

The first 6 mono channels of the M810/M1610 have been equipped with an input TRIM

control and are also protected by an overload protection circuit. The TRIM controls are

used to make sure that an ideal signal level is flowing through the channel, no matter

what the input source. Each channel has a green LED that will flash when the proper sig-

nal level has been reached. The channel overload protection circuit will provide additional

protection from clipping on peaks of up to 16 dB above normal operating levels.

To set the TRIM

i. Turn down the channel LEVEL control,

ii. With a normal signal present at the input, turn up the TRIM control until the green

LED just starts to flash (when the signal peaks).

iii. You can then use the LEVEL control to set the channel volume level. Increasing

the TRIM beyond this point will compress the signal on that channel.

3. Channel LEVEL Controls and CLIP LEDs

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 LEVEL 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 M810/M1610 has 5 busses: MAIN

(left and right), MONITOR, EFFECTS and RECORD OUT.

4. Channel Lo, Mid, and Hi Equalization

The M810/M1610 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 equalization consistent with the clean simplicity of the M810/M1610’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 LEVEL setting and/or the Equalizer if clip activity is excessive.

Note: The center position reflects a neutral or flat EQ control setting; however, turn-

ing down EQ settings can be used effectively to reduce feedback and/or distortion).

5. Channel MON Controls

The MON control (monitor send) on each channel varies the amount of signal being sent to

the monitor bus in the M810/M1610. In the mono channels the MON signal is pre-LEVEL

control, post-EQ and post-TRIM. It is taken before the LEVEL control so the monitor signal

can be mixed independently of the MAIN mix. As a result, channel EQ and TRIM settings do

affect the sound of the monitor signals, while the channel LEVEL controls do not affect the

MON signal. The MON signal in the stereo channels is pre-LEVEL 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.

6. Channel EFX Controls

The EFX control (effects send) for each channel adjusts the level of the channel signal

being sent to the M810/M1610 effects bus. This signal is post-LEVEL control and post-EQ,

the sound is affected by both the channel EQ controls and the channel LEVEL control. The

signal from the effects bus is internally routed to the Digital Effects Processor. The chan-

nel EFX control regulates the intensity of the built-in digital effects for the channel’s out-

put. When using the built-in digital effects, you can connect a standard on/off footswitch

(e.g. Yorkville model IFS-1A) 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.

Tip: Alternatively, this signal at this jack can be connected to the input of an exter-

nal 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 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 LEVEL controls also affect this signal.

7. 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 6, and by the Bal control in channels 7/8

and 9/10. 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 level in the right

channel to zero. 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.

Master Section

1. MAIN Master Control

The MAIN master control adjusts the over-

all level of the main mix, the PA volume.

Note: To ensure maximum signal head-

room and clarity, set the channel TRIM

and LEVEL controls first for a good sig-

nal 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.

3. MAIN EFFECTS Return Control

The MAIN EFX control regulates the amount of signal going from the output of the inter-

nal Digital Effects Processor to the MAIN mixing bus where it is mixed with the dry signals

directly. It controls the intensity of the effects on the left and right MAIN output signals.

4. MON EFFECTS Return Control

The MON EFX control regulates the amount of signal going from the output of the

internal Digital Effects Processor to the MON mixing bus where it is mixed with the dry

signals directly from the channel MON send controls. It controls the overall effects

intensity for the MON Out signal.

5. Pre-EQ OUT, Post-EQ OUT

These jacks offer a variety of patching and routing options. They are positioned in the

signal path before and after the M810/M1610 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 M810/M1610 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 Pre-EQ jack. Mono operation of this

jack is switched to left channel only as soon as a jack is inserted in the R Pre-EQ

jack. The Post-EQ OUT jacks are not linked in this manner. 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 ampli-

fiers. 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 M810/M1610 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 (or Pre-EQ OUT) to the device’s input jacks and then from the

device’s output jacks to the M810/M1610 Power AMP A IN and Power AMP B IN jacks.

You can connect another mixer to the M810/M1610 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 M810/M1610 L and R Pre-

EQ OUT (or Post-EQ OUT) to inputs on another mixer connected to other amplifiers driving a PA

speaker system while using the M810/M1610’s A and B amps to power control room speakers.

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, located just below the MAIN 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 equal-

ization 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 men-

tioned under #5. Pre-EQ OUT, 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.

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 7/8 (channel 9/10 or any of

the other channels). Use the LEVEL 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 sig-

nal added to the monitor mix. Make sure that its EFX control on the channels are

turned off. An alternative could 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 M810/M1610 is plugged in, turned on and all

systems are normal. The Clip/Protect LEDs normally indicate clipping in the amplifiers.

They will remain illuminated and the power LED will turn off in the unlikely event that

the amplifiers overheat or if DC voltage is detected on the output. The AC power on/off

switch is on the rear panel of the M810/M1610.

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 LEVEL up will create a large transient,

resulting in a loud, potentially damaging pop. When setting up, either turn off the AC

power, the phantom power, or set all channel levels to zero. The Phantom Power push-

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 1-8 Switch

The M810/M1610 includes a feature that enables users

to instantly mute channels 1-8. Depressing the Mute 1-8

switch will mute channels 1-8 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 9/10 will remain active, leaving this

channel open for allowing a microphone or CD player, cas-

sette 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 deactivate.

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 master’s output

is routed through Equalizer B and then to both the Amp B power amp channel

and to the MON Out jack.

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 ro-tates 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 M810/M1610.

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 con-

trol (for that channel) is turned off, the channel’s wet effects will still be audiable 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 digi-

tal 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 M810/M1610 there are

nine sliders for each channel, each one operating over a 2/3-octave portion of the mid-

range 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 fre-

quency 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 individual-

ly 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.

ii. To adjust for deficiencies in the speaker system’s high frequency and bass response,

the M810/M1610 also has a 2-band rotary shelving equalizer. These work in conjunc-

tion with the 9-band graphic. Yorkville engineers have developed this technique to

provide you with greater tone shaping capability. This allows the graphic equalizer

bands frequencies to be spaced at closer intervals, which mean better selectivity for

feedback reduction and sound shaping. You may want to turn up the Lo and Hi con-

trols to give the system a more HiFi sound when you’re playing at lower volumes. At

higher volume levels, you may need to turn these controls down, this will help maxi-

mize the volume and tighten up the sound.

iii. The third use of the graphic equalizer is to adjust the sound character for artistic

reasons. The frequencies are adjusted until the sound feels best to the musicians.

M810/M1610 Rear Panel

1. Power Amplifiers

Each of the M810/M1610 dual power amplifiers has two ¼-inch jacks and 1 Speakon

jack for speaker connections. The power amplifiers are designed to provide full power into

a 4-ohm load. Connecting two 4-ohm speakers (2-ohm load) to either AMP A or AMP B

will not harm the M810/M1610 but the maximum power output may be reduced.

WARNING: Do not obstruct the flow of air around the vents on the rear of the

M810/M1610, this may cause the power amplifier to overheat. The amplifier will

start to reduce its power output in order to keep running. In extreme cases it may

be forced to shut down. If the clip LEDs are illuminated continuously and the Power

LED is off, this will indicate shutdown. After the M810/M1610 cools down, operation

will be restored automatically This condition should not occur if adequate ventila-

tion is provided at the back of the unit.

2. Power Switch and Breaker

The Power switch and circuit breaker are located on the rear panel. If the circuit breaker

trips during use, wait a few minutes (to cool), then push in to reset. The circuit breaker

can trip if the amplifier is too heavily loaded with long periods of continuous tones (such

as feedback). If the circuit breaker trips immediately after being reset, take the unit to

your Yorkville dealer for service.
