General
When using the built-in amplication it is important not to block the air intake vents on the front and side panels. These are essential for the dual speed fan to keep the unit cool during operation. Avoid exposing the unit to rain or excessive levels of humidity during operation.
1) IEC power input - use this standard IEC connector to connect the DIGIMIX to the mains. This socket supplies power to both the Mixer and the Amplier Sections of the unit and also has a
built-in fuse holder.
2) Power Switch - Use this switch to turn ON & OFF the mains power supply to the DIGIMIX.
3) Phantom Power Switch - The DIGIMIX mic inputs feature a 48V Phantom Power System to fa-
cilitate the use of Condenser Microphones that require an external power supply. To use; move the switch marked ‘Phantom’ (found on the rear panel) to the ON position and phantom power will be delivered to all six XLR mic input connectors. There should be no adverse affect using a mixture of powered Condenser mic’s and standard dynamic mic’s simultaneously. The Dynamic mic’s should not be affected by the phantom power supply. When the Phantom power system is active you should see the +48V red status LED in the Main Level Meter LED area illuminated.
The ‘Channel Strips’ (see diagrams) on pages 4 - 12
4) XLR Input (mic channels 1 to 6 only) - Use this mic level XLR input to connect your microphones.
You can use dynamic or condenser microphones with the DIGIMIX. You cannot use this XLR
connection for line level audio signals.
5) Line Input - (mic channels 1 to 6 only) - Use these 1/4” jack sockets to attach any line level audio source (keyboard, CD Player etc). This socket is electronically balanced so accepts either a
balanced or unbalanced audio signal and automatically self adjusts accordingly.
6) Channel Insert connections ( Channels 1 to 6 only) - The microphone channels feature an
‘insert’ system. These are commonly used to connect automatic gain control devices such as
Compressors and Noise Gates. The Insert system follows industry standard protocol. To use it you will need a specially congured ‘Y Insert Cable’. These cables have a single stereo 1/4” jack connector at one end and a pair of standard mono 1/4” jack connectors at the other. To use the system you connect the single stereo jack connector to the appropriate ‘Channel Insert’ connection
found on the rear panel of the unit.
7) L (MONO) & R Line inputs (Channels 7 to 10 only) - Use these unbalanced 1/4” jack sockets to connect any line level audio source. Use the L input when you wish to attach a mono source as this
socket is automatically split and sent to both L & R channels of the main mix when there is no connection to the R input. Use both connections when connecting a stereo source
(e.g. a CD Player).

8) Lo Cut Switch (mic channels 1 to 6 only) - This button applies an 18dB per octave high pass lter that completely removes all frequencies below 75Hz. We highly recommend using this lter for hand held vocal microphones because it reduces handling noise. It is also worth while using it
for any microphone or instrument that is not intended to produce bass because it also reduces the chances of low frequency feed back and can deliver
an overall mix with greater clarity.
9) Gain - Use this control in conjunction with the PFL
system & the level meters to adjust the input signal level
so that it peaks around the 0dB mark on the level meter. You will notice two different sets of calibration around the
control. This is because the gain circuit applies a different amount of gain to the microphone and line
inputs. The +4 marking corresponds to the ‘Unity’ setting
for a signal at the standardised professional line level of
+4dBu. The -10 marking corresponds to the ‘Unity’ position for a standard domestic line level -10dBu
signal. These two markings are there to show you where to position the gain control so that the gain circuit is neither increasing nor decreasing the signal level for each different line level signal type.
10) EQ - The mic channels (1-6) and line channels (7-10) feature different types of EQ system. The mic channels - Feature 3 band EQ with a swept mid control. The Hi control applies +/-15dB of cut and boost to frequencies centred on 12kHz. The low control applies +/-15dB of cut or boost to frequencies centred on 80Hz. The mid section has two controls; the upper control sets whether you cut or boost by +/-15dB.
The lower control lets you choose which mid range
frequency you cut/boost. As with all mid range EQ
systems you are effectively adjusting a ‘notch’ or ‘band’ of frequencies above and below the selected ‘centre’ frequency.
The Line Channels - feature 4 band EQ. The Hi control applies +/-12dB of cut and boost to frequencies centred on 12kHz. The Hi Mid control applies +/-15dB of cut or boost to frequencies centred on 3kHz. The Lo Mid control applies +/-15dB of cut or boost to a ‘band’ of frequencies centred on 500Hz. The Lo control applies +/-12dB of cut or boost to frequencies centred on 80Hz
11) Aux 1 ‘AUX’ - Use this control to set the amount of signal sent to the line level audio output marked ‘Aux Send’ in the master connections section. How to set up the Aux Send & return system is explained under Master Connections.

12) Pre Button - This button relates to the Aux control. When the button is ‘down’ the signal from this channel is sent to the Aux output connection before it reaches the channel level fader - so adjusting the channel level fader has no impact on the Aux Send Level. When the button is in the ‘UP’ position the signal from the channel is routed to the Aux Send connection after it has passed through the channel level fader - so when the button is ‘UP’ turning down the level fader also turns down the signal sent to the Aux Send. This is useful when using the Aux Send System to set up an on stage monitor mix as it enables creation of a separate mix with levels that differ from those of the main mix.
13) Aux 2 ‘FX’ - Use this control to adjust the signal level sent to the on board effects processor. To aid in versatility the DIGIMIX II also provides a line level output marked ‘EFX Send’ in the master connections section. This output can be used to connect an external effects processor instead of the on board processor. The ‘EFX Send’ is wired ‘Post Fade’ so adjusting the channel fader also adjusts the EFX Send level (to both the on board effects processor and the external EFX Send connection).
14) Pan - When this control is in the central position equal proportions of the channel signal is sent to the Left and Right channels of the main mix. Turn the control left and more signal will be sent to the Left channel of the main mix. Turn the control to the right and more signal will be sent to the Right channel of the main mix.
15) PFL/Solo - This sends the channel audio signal to the PFL/Solo system (described in the PFL/ Solo section of this manual). This signal is sent ‘Pre Fade’ and pre EQ so the measured signal is not changed by the position of the channel level fader or EQ controls... but the signal is taken immediately after the channel Gain control (and thus the Insert Sockets), so you are essentially measuring the input signal level after you have adjusted it with the input Gain control.
16) Peak LED - This LED illuminates when the channel signal level is approaching a level at which it may distort. It is there to act as a warning to you so that you can reduce the particular channel
level faders to avoid distortion.
17) Mute/Alt 3 & 4 - This button performs two tasks at once when pressed.
1. It mutes (silences) the channel from the main mix.
2. It routes the signal to the ‘Alt 3 & 4’ system (as described in the ‘Alt 3 & 4’ section of this manual).
18) Alt 3&4 LED - When the Alt 3 & 4 button is engaged this amber LED illuminates to remind you that you have routed this particular channel into the Alt 3 & 4 system
19) Channel Fader - Use this 60mm fader to adjust the relative level of the channel in the main mix

The Aux & Effects Systems
Using an Aux System
The idea of an Auxiliary Send & return systems is that it enables you to send a signal out of the mixer, to an external processor (usually it is an effects unit), through the external processor, then back to the mixer.. and back into the main mix. The on board effects processor on the DIGIMIX is accessed exactly as though it were an external processor. When you wish to send sound to it you use the ‘Aux 2 EFX’ send and return system. Aux 2 EFX also features Send and Return connections so can be used with an external Effects processor should the need arise. The descriptions of all connections etc below apply therefore to both ‘Aux1’ and ‘Aux 2 EFX’.
20) Aux Send connections - Use a cable to connect from this mono line level 1/4” jack socket to the input of your external processor.
21) Master Aux Send Level controls - Use these to set the master Send Level for the Aux Send system. These controls set the overall level of all of the signals sent to the Aux Send & Return systems via the Aux Send controls in the channel strips.
22) Aux Send PFL buttons - Press these buttons to route either Aux Master signal to the main Level Meter (and solo it) so that you can measure it (and hear it isolated). Many External Effects
processors do not have input level meters so it is wise periodically to measure the Send Level signal to ensure that the signal is neither too large nor too small.
23) Aux Return Connections - Use a pair of cables to connect these line level 1/4” jack input sockets from the output of your external processor to your mixer.
24) Aux Return input level switches - Use these buttons to determine whether each Aux Return connection operates at either the professional Line Level Standard of +4dBu or the Domestic line level standard of -10dBV.
25) Aux Return Level faders - Use these faders to set the relative level of the Return signal (from your external processor) and the internal effects processor to the main mix.
On Board Effects
The DIGIMIX on board Effects System provides a carefully selected range of 99 high quality
Effect Programmes with variable time parameters. They are designed to be as versatile as
possible and to meet your requirements for a wide range of uses. Operation is also extremely simple.

26) Programme LED - This large two digit LED display shows the currently selected programme.
27) Up & Down buttons - Use these increment buttons to select the Effect programme you wish
to use from the list. Press either button once to move up or down through the list. When you have selected the desired programme you may then alter the timing of the delay/reverb by using the UP/DOWN buttons. To alter the timing of the selected effect press the enter button and the arrow
displayed at the side of the selected effect will move down the display and will point to the letter T.
You can then alter the delay/reverb time by using the UP/DOWN buttons.
28) Enter button - Use this button to select between effect and delay/reverb time.
29) EFX Processor Direct In - In addition to routing signals to the on board Effects Processor you
can use these line level 1/4” jack input connections to route external signals directly into the Effects Processor. When you do this the signal passes through the processor and arrives in the main mix via the EFX Return Level Fader.
The Master Section
The Master Section of the DIGIMIX is extremely versatile and highly specied for a mixer in this
class. The are various ways in which you can connect and use this product.
Main Mix
There are three sets of main Output connections which all simultaneously carry the full stereo main mix.
30) XLR R&L - These two line level balanced XLR connectors (found on the rear panel) are your primary outputs, they are the least prone to interference because they are of a balanced XLR type.
31) Master Insert connections - These stereo 1/4” jack sockets are Insert connection points for the master output connections. They function in exactly the same manner as the Channel Inserts.
There are 99 effects in the DSP as follows:
1 Reverb Hall 2.0 sec 2, Reverb Hall 2.5 sec 3, Reverb Hall 3.0 sec 4, Reverb Hall 4.0 sec 5, Reverb Hall 5.0 sec 6, Reverb Hall 6.0 sec 7, Reverb Hall 8.0 sec 8, Reverb Hall 10.0 sec 9, Reverb Room 1.0 sec 10, Reverb Room 1.5 sec 11, Reverb Room 2.0 sec 12, Reverb Room 2.5 sec 13, Reverb Room 3.0 sec 14, Reverb Room 4.0 sec 15, Reverb Plate 1.0 sec 16, Reverb Plate 1.5 sec 17, Reverb Plate 2.0 sec 18, Reverb Plate 2.5 sec 19, Reverb Plate 3.0 sec 20, Reverb Plate 4.0 sec 21, Ambient 0.5 sec 22, Ambient 0.7 sec 23, Ambient 1.0 sec 24, Ambient 1.3 sec 25, Ambient 1.6 sec

32) XLR Level switch - Use this switch to determine whether the main XLR Output Connectors (30) operate at either the Professional Line Standard of +4dBu or the Domestic Line Level Standard of -10dBV.
33) Rear Panel Main Outputs - These line level 1/4” jack connectors carry the stereo main mix
and can be used for a variety of purposes.
34) Top Panel main Outputs - These line level 1/4” jack connectors carry the stereo main mix
and can be used for a variety of purposes.
35) Main Mix L&R Level faders - Each of these two faders control the Level of one side of the
stereo main mix as sent to all of the various connectors that carry the main mix.
Graphic Equaliser - The 7 band Graphic Equaliser is only applied to the main mix
36) EQ In - This button switches the Graphic Equaliser ON and OFF
37) EQ Frequency faders - Five of these faders (the ones marked 160Hz, 410Hz,1.1Hz, 2.3Hz
and 6.2Hz) relate to a narrow band of frequencies. When placed at the calibrated ‘zero’ position
they have no effect, but when pushed up or pulled down they cut or boost the relevant band of
frequencies by +/-10dB. The faders at either end are a little different, they are ‘shelving lters’; the lower one cuts and boosts all frequencies below 60Hz (I.E. bass) and the upper one cuts and boosts all frequencies above 15.6kHz (I.E. high treble & hiss).
The main Level Meter (38)
This ‘enclosed bar type’, 3 colour, stereo level meter provides an accurate audio signal level
measuring tool. It can be used to measure a broad range of signals. When the PFL & Solo
status indicators remain un-illuminated the meter will be measuring the stereo signal of the main
mix. When either the PFL or Solo status LED’s are illuminated the meter will be measuring a signal source you have selected by pressing one of the many PFL/Solo buttons found on the mixer.
An optimum signal level is one where the meter peaks regularly at around the ‘zero’ dB calibrated segment (at the top of the green coloured section). It is perfectly acceptable for the meter to be
peaking in the amber sections of the meter, but when they are coloured amber, they are there to
warn you that you are approaching the red segment. If the meter is peaking at the red segment
your sound is probably ‘clipping’ and sounding distorted and should be turned down.
PFL/Solo
39) PFL/Solo button - This button switches the PFL Solo system between it’s two different
operating modes.
When in the ‘UP’ or ‘PFL’ position; the DIGIMIX routes any selected signals to the Main Level Meter (39) so that they can be measured. The amber PFL status LED in main Level Meter area
also illuminates.
When in ‘Down’ or ‘Solo’ position’ in addition to routing the signal to the Main Level Meter, the mix­er mutes all of the channels and inputs to the DIGIMIX so that you only hear the individual channel (s) selected via PFL/Solo buttons. The Solo LED in the master section also illuminates. You can actually press the PFL/Solo buttons for several channels/sources at once... meaning that you can listen to how several channels/sources sound together isolated from the rest of the mix.. and/or measure their signal levels in isolation.
9
Control Room
The DIGIMIX features a ‘Control Room’ system. In a recording studio this is often used for connection of the Mixing Console to the monitor system (speakers) used by the recording engineer. It’s main purpose is to provide a convenient routing and level control system for the engi-
neer to use.
40) Control Room Connections - Use an appropriate audio cable to connect these line level 1/4” jack connectors to the audio input for whichever speakers are to be used by the mix engineer.
41) Control Room Level control - Use this rotary control (conveniently located on the front panel near the main Mix Level Faders) to adjust the signal level sent via the control Control Room
System outputs.
Located around the Control Room Level control you will nd three buttons; each of these buttons routes a different audio source to the Control Room output connections. The three options for routing to the Control Room system are (42) Main Mix (which is the main stereo mix), (43) 2 Track ( which is the signal from the 2 Track input) and (44) Alt 3 & 4 (which is the signal from the Alt 3 & 4 system)
2-Track
The 2-Track system is designed for recording, particularly recording at a gig.
45) 2-Track connections - Use these unbalanced line level RCA type
connections to attach your recording
device. Connect the L&R set marked ‘Tape In’ to the Record Input sockets of your recording device. Connect the L&R marked ‘Tape Out’ to the Output
or playback sockets of your recording device.
43) 2-Track to Control Room - Use
this button to route the signal from the
2-Track ‘Tape Out’ connectors to the Control Room system output.
46) 2-Track to Main Mix - Use this
button to route the signal from the
2-Track ‘Tape Out’ connectors to the Main Mix Level Faders and various Main Mix output connections.

Alt 3&4
The Alt 3 & 4 System is a powerful ‘routing system’ that enables you to set up a second separate mix to the main mix that can be used for recording or setting up stage monitors or simply as a traditional ‘Sub Mix’. The classic use for a traditional sub mix is to route all of the microphones
on a drum kit, or all the microphones for a brass section, or all the microphones used for backing
vocals to a single fader; so that you can adjust the entire group with one fader movement.
Any channel that is routed to the Alt 3 & 4 System via the Alt 3 & 4 button is removed from Main Mix and sent instead to a set of line level 1/4” jack connections on the rear panel marked
‘Alt 3 & 4 Outputs’ (47).
Before the signal gets to those rear panel outputs it goes via the fader in the master section marked ‘Alt 3 & 4’ (48) - you use this fader to adjust the combined level of all of the channels you
have currently selected to route to the Alt 3 & 4 system.
There is a button above the fader marked Alt 3 & 4 to Mix (49) that simultaneously routes the ‘Alt 3 & 4 Mix’ back to the main mix (post fader) so that you have the option of routing the selected channels to this additional ‘Sub Mix’ and sending it onwards to the Alt 3 & 4 outputs but without also losing it from the Main Mix. There is a button marked ‘Alt 3 & 4 PFL’ (50) that routes the entire Alt 3 & 4 Mix to the PFL/Solo System & Main Level Meter for measure etc. There is a button beside the Control Room Level (44) that routes the combined Alt 3 & 4 Mix to the Control Room System.
51) Alt 3&4 Insert connections - These stereo 1/4” jack sockets are Insert connection points for the Alt 3 & 4 output connections. They function in exactly the same manner as the Channel Inserts
(6).
52) Phones - Use this standard head phone connection socket to attach a set of headphones for
monitoring purposes (minimum impedance 16 Ohms).
The Amplier
53) Input connections - Use these line level 1/4” jack sockets to connect an input audio signal to the built-in Amplier.
54) Amplier Input Level controls - Use these L&R rotary Level controls to adjust the overall listening level of any speakers connected to the DIGIMIX Amplier speaker outputs.
55) Speakon Type Speaker Output connections - Use appropriate cables to connect these
speakon type speaker output connectors to the input connections of your speakers. Speakon is
the industry standard connection method for connecting speakers to power ampliers; it is safe,
secure and delivers superior audio sound.
The speakon uses Pin1+ and Pin1- to connect to the loudspeaker.
11
56) Binding Post Speaker Output connectors - Use appropriate cables to connect these
Binding Post speaker output connectors to the input connections of your speakers. Binding Posts
are designed to accommodate bare wire ends of speaker cables; this is a speaker connection
method which although safe and reasonably secure when handled correctly and capable of delivering good quality audio sound... and undeniably convenient in the sense that any speaker cable can rapidly be turned into a set of bare wires in an emergency... is not our recommended connection method.
57) Footswitch Socket - The footswitch socket turns the selected reverb/echo setting on or off.
Note: The DIGIMIX has a rated power output that delivers the following:
2 x 300W RMS @ 8 Ohms 2 X 550W RMS @ 4 Ohms
Be sure to match the rated power handling capacity of your speakers to the DIGIMIX power output to avoid damaging your speakers.
Rack Mounting
To rack mount the DIGIMIX remove the screws on the outside edge of each of the plastic side
cheeks.
