2.2 D-MIX500 Installation

Installation

The D-MIX500 is designed for reliability and high performance, and is built to the
highest standards. Whilst great care has been taken to ens ure that installations are made
as troublefree as possible, care taken at this stage, followed by correct setting up will
be rewarded by a long life and reliable operation.

Wiring Considerations

(A) For optimum performance it is essential for the earthing system to be clean and
noisefree, as all signals are referenced to this e arth. A c entra l point should b e dec ided
on for the main earth point, and all earths should be ’star-fed’ from this point. It is
recommended that an individual earth wire be run from each electrical outlet, back to
the system star point to provide a safety earth reference for each piece of equipment.

(B) Install separate mains outlets for the audio equipment, a nd feed these independently
from any other equipment.

(C) Avoid locating mains distribution boxes near audio equipment, especially tape
recorders, which are very sensitive to electromagne tic fields .

Power Supply

Always ensure that you use the correct PSU for your mixer The D-MIX500 uses a
D-MIX500 power supply. There are three different PSU voltages for different
geographical areas.

Part No. Voltage

HB0166 USA 120V
HB0167 UK 230V
HB0169 EUR 22 0V

Warning!

Before switching on your D-MIX500 console, check that
the power supply unit is the correct one for your area.

D-MIX500 Installation 2.3

Precautions and Safety Instructions

General Precautions

Avoid storing or using the mixing console in conditions of excessiv e heat or cold,or in
positions where it is likely to be subject to vibration, dust or moisture. Do not use any
liquids to clean the fascia of the unit: a soft dry brush is ideal. Solvents may cause
damage to paint or plastic parts.

Avoid using the console close to strong sources of ele ctromagnetic radiation (e.g video
monitors, high power electric cabling): this may cause degradat ion of the audio quality
due to induced voltages in connecting leads and chassis. For the same reason, always
site the power supply away from the unit.

Caution!

In all cases, refer servicing to qualified personnel.

Handling and Transport

The console is supplied in a strong carton. If it is ne cessary to move it any distance after
installation it is recommended that this packing is used to protect it. Be sure to
disconnect all cabling before moving. If the console is to be regularly moved we
recommend that it is installed in a foamlined flightcase. At all times avoid applying
excessive force to any knobs, switches or connectors.

Power Supplies & Cables

Always use the power supply and cable supplied with the mixer: the use of alternative
supplies may cause damage and voids the warran ty; the extension of power cables may
result in malfunction of the mixing console.

Warning!

Always switch the power supply off before connecting or
disconnecting the mixer power cable, removing or
installing the Cross Fader, and servicing. In the event of
an electrical storm, or large mains voltage fluctuations,
immediately unplug from the mains.

2.4 D-MIX500 Installation

Signal Levels

It is important to supply the correct input levels to the console, otherwise signal to noise
ratio or distortion performance may be degraded; and in extreme cases, damage to the
internal circuitry may result. Likewise, on all balanced inputs a void sources with large
common-mode DC, AC or RF voltages, as these will reduce the available s ignal range
on the inputs. Note that 0dBu=0.775V RMS.

The microphone inputs are designed for use with balanced low impedance (150 or 200
ohms) microphones.

The Phones output is a 3-pole "A" gauge jack, suitable for high or low impedance
headphones (8ohms - 2kohms).

Caution!

Do not use unbalanced microphones or battery powered
condenser microphones without isolating the +48V
phantom power: degraded performance or damage to the
microphone may result.

The sensitivity of the Mic inputs is variable from -15dBu to -50dBu, with a maximum
input level of +4dBu. The Mono Line Input sensitivity is variable from -20dBu to
+15dBu with a maximum input level of +30dBu.

The Stereo Input is provided with a gain trim of +/-10dB, with a maximum input level
of +32dBu for CD or AV inputs. Vinyl inputs are suitable for moving magnet cartridges.

The main outputs of the mixer (Left/Right) are balanced at a nominal level of +4dBu.
Maximum output level is +26dBu into 5kohms.

D-MIX500 Installation 2.5

Connecting The Inputs - Examples

Example 1

In this example, 2 CD players are connected: one each to channels 1 and 7. There is also a turntable connected to channel

5. The DJ’s mic would normally be plugged into mic 1 (channel 3) via the front panel, and is therefore not shown in this
diagram; an additional mic shown is connected to mic 2 (channel 4). This may be used by, for example the MC. Finally
there is an Effects unit and a limiter/compressor connected to the FX insert point: these would be used by the mic channels.

Example 2

In this example, 2 turntables are connected: one each to to cha nnels 2 and 6. There is also a CD pla yer connected to channel

5. The DJ’s mic would normally be plugged into mic 1 (channel 3) via the front panel, and is therefore not shown in this
diagram. Other options may include a Cassette Deck conne cted to channel 7, and a Video Disk Player connected to cha nnel
1, for example.

2.6 D-MIX500 Installation

Connecting The Outputs - An Example

In the example below, a 2-channel graphic equaliser is connected to the main outputs’ insert points. The main outputs are
driving power amps, with speakers on the main dance floor. A secondary dance floor is served b y power amps and speakers
which are driven by the stereo 2 outputs. A bar or foyer area may have a mono amp and speaker which is, in the example
shown, fed from the mono 1 output.

D-MIX500 Installation 2.7

Connecting the DJ System Outputs - An Example

In the example below, the DJ booth amps and speake rs are shown fed from the Booth outp uts. There is also a tape recorder
to record the console’s output, this is connected to the record sockets. Finally, a lighting controller is fed from the lights
output.

jacks and RCA phono connectors. This section describes how to connect external
equipment to the console. Correctly-made cables of the proper type will ensure peak
performance from your mixer.

Inputs

XLRs

The mic input accepts XLR-type connectors and is designed to suit a wide range of
BALANCED or UNBALANCED low-level signals. Professional dynamic, condenser
or ribbon mics are best because these will be LOW IMPEDANCE. While you can use
low-cost HIGH IMPEDANCE mics, you do not get the same degree of immunity to
interference on the microphone cable and as a re sult the level of background noise may
be higher. If you turn the PHANTOM POWER on, the socket provides a suitable
powering voltage for condenser mics.

Jack Sockets

The 1/4" input jacks on this console fall into one of two categories: balanced inputs
and unbalanced inputs. The diagram on the left shows the connections for both types.

The following input jack sockets are balanced:
AV1 Left, AV1 Right, Input A, Input B, AV2 Left, AV2 Right, Main Output Insert

Return Left and Main Output Insert Return Right.
These inputs accept 3-pole 1/4" "A" gauge (TRS) jacks, or 2-pole mono jacks which

will automatically ground the "cold" input.
These inputs are BALANCED for low noise and immunity from interferenc e, but you

can use UNBALANCED sources by wiring up the jacks as shown left, although you
should then keep the cable lengths as short as p ossible to minimise interference pick-up
on the cable. Note that the ring must be grounded (by linking it to the sleeve ) if the
source is unbalanced.

The FX Insert Return jack socket is unbalanced. It will accept a 3-pole 1/4" "A" ga uge
(TRS) jack, or a 2-pole mono jack. It you use a 3-pole jack, the ring must be linked to
the sleeve.
