packaging, in case of future re-shipment.
INSTALLATION
-Electrical Considerations:
The D10, D20 and D100 devices have been manufactured to comply with your local power
supply requirements, but before connecting the unit to the supply, ensure that the voltage
(printed on the rear panel) is correct, and that a main fuse of the correct type and rating has
been fitted. Make sure power outlets conform to the power requirements listed on the back
of the unit. Damage caused by connecting to incorrect AC voltage is not covered by the
warranty.
-Mechanical Considerations:
To ensure that this equipment performs to specification, it should be mounted in a suitable
rack or enclosure. When mounting the unit in a rack or enclosure, ensure that there is
adequate ventilation. The cooling fan sucks cool air in through the right side and blows warm
air out of the left side of the unit through the ventilating grills. Take care when mounting
other equipment in the same rack.
-Operation:
Read all documentation before operating your equipment and retain all documentation for
future reference. Do not spill water or other liquids into or on the unit and do not operate the
unit while standing in liquid. Do not block the fan intake or operate the unit in an
environment that could impede the free flow of air around the unit. If the unit is used in an
extremely dusty or smoky environment, it should be cleaned of any collected debris at
regular intervals.

1: Power Switch: This single pole switch turns the amplifier fully off (but does NOT isolate it from the mains
supply).
2: Power LED: This indicates when the amplifier is active. This does NOT indicate the presence of a mains
supply when the power switch is OFF.
3: Attenuation Controls: These are analogue controls allowing precise level settings. Note that in bridged
(mono) mode some controls may be inactive.
4: A/P (Auto Protect) LED: If a condition exists, either internally or externally, that could cause damage to either
the amplifier or the speakers, the protection circuit will disengage the outputs and the A/P LED will illuminate.
The amplifier will continue to be monitored and depending on the type of fault, will either reset after the fault
has cleared or require manual resetting by switching off at the mains switch and then on again after a few
seconds. If the outputs are shorted or if DC is present, the protection circuit will disengage the outputs and the
A/P LED will illuminate. Temperature related faults will reset if the unit has cooled sufficiently. Output short
circuits will require manual reset after clearing the fault.
5: Bridge LED: This illuminates when a channel pair have been switched into bridged (mono) mode (channel A
+B or C+D). Note that the partner channel’s LEDs and controls are disabled when a pair of channels are
bridged. Bridge switches are on the rear panel.
6: The D-10 and D-20 have Signal LEDs that are active from a minimum output level of approximately 10 Watts
and are an indication only of signal presence. The D-100 has Signal Meter and OCM indicators: LED bar graphs
show instantaneous level on each channel to indicate proximity to the limiter threshold. Note that if the PRC
system is in operation on any channel, this will affect the readout shown on the respective meter. The red LED
in the meter will illuminate when the limiter threshold has been reached and limiting is occurring. The output
current monitor (OCM) may activate to limit the output current of the amplifier channel - this can occur even if
the amplifier has not reached clipping point. The OCM indicator can operate independently of the bar graph
meter. Typical conditions that may trigger the OCM circuitry would be very low load impedance, or high
subsonic or VHF levels.
7: Limit LEDs: The amplifiers incorporate signal limiters, which are preset to prevent clipping with high levels of
drive. The amber LEDs on the front panel illuminate to indicate operation of the limiters.
8: Link LED: This indicates if the channel is linked to its immediate neighbour. If this is illuminated, the
attenuation control of the channel to the immediate right will not function as both channels are being fed
from the left hand channel. The link switches are on the rear panel.
9: PRC LED: This illuminates if the Power Reduction Control has been enabled on the respective channel. PRC
switches are on the rear panel.

1: Input XLR sockets: Connect signal inputs to these sockets, wired pin 2 hot, 3 cold, 1 ground. For
sensitivity and impedance of these inputs, please see the specifications on page 11. When running in
bridged (mono) mode, only input A is used (except D-100).
2: D-10 & D-20
Channel A output Speakon socket: Normal output is on pins 1+ hot, 1- cold. Channel B's output is also
wired to this socket to enable a single NL4 to provide both channels and to facilitate easier wiring in bridged
mode. Channel B is wired pins 2+ hot, 2- cold. Channel B output Speakon socket: Normal output is on
pins 1+ hot, 1- cold.
D-100
Channel A output Speakon socket: Normal output is on pins 1+ hot, 1- cold. Channel B's output is also
wired to this socket to enable a single NL4 to provide both channels and to facilitate easier wiring in bridged
mode. Channel B is wired pins 2+ hot, 2- cold. Similarly channel C's output Speakon socket carries Channel
D's output. Check the table on the rear panel for details.
3: D-10 & D-20
Bridged (Mono) switch: Depress this switch to run the amplifier in bridged mode. Note that the output must
be taken from channel A's output Speakon connector, on pins 2+ hot, 1- cold.
D-100
Bridged (mono) switch (A+B): Press this switch to run this pair of amplifier channels in bridged mode. To run
C+D bridged, press the switch on the far left of the panel, beside channel D's input XLR.
4: Mains inlet (only D-10) & Power Cord.
5: Fan outlet: The variable speed fans suck air in through the front vents and out through the back of the
amplifier.
6: Link out XLR sockets: These are passively connected directly to their respective inputs to allow for parallel
input connections to other amplifiers. As such, they will function even if the amplifier is turned off.

CONNECTIONS
INPUTS
The inputs are made via 3-pin XLR connectors, which are electronically balanced and should be connected via a
high grade twin core screened cable, as follows:
PIN2 - Hot (signal +). Signal Hot.
PIN3 - Cold (signal -). Signal Cold.
PIN1 - Screen (see note).
Connected to the chassis of the unbalanced equipment or left disconnected at the unbalanced end.
The amplifier is designed to operate with fully balanced equipment and ground loops or loss of performance
may be experienced if connected to unbalanced sources.
NOTE: This amplifier is wired to the latest industry recommendations. PIN1 is connected directly to the chassis/-
mains earth. If ground loops (mains hum) are encountered remove the screen connection from the other end of
the cable and leave it open circuit. If problems persist, consult your dealer/supplier.
DO NOT TAMPER WITH OR ALTER ANY GROUND (EARTH) CONNECTIONS INSIDE THE AMPLIFIER.
D-10 & D-20: For bridged operation input should be made to channel A only and the rear panel switch set for
bridged mode. Channel B will then be fed out of phase with channel A.
D-100: For bridged operation input should be made to channel A (or C) only and the rear panel switch set for
bridged mode for the appropiate pair of channels.
OUTPUTS
The speaker outputs are via Neutrik Speakon connectors. Only 2 of the 4 poles are used. 2 pole (NL2FC) or 4 pole
(NL4FC) connectors can be used. Terminations are as follows :
HOT Pin +1
COLD Pin -1
Additionally Channel A Speakon connector carries Channel B output on Pins +2 & -2 to allow easy bi-amping or
bridged operation.
HOT Pin +2
COLD Pin -2
NOTE: 1.- Although the "cold" output terminals are nominally at 0V., they should not be joined together,
otherwi-se cross-talk may be introduced. 2.- Because the currents involved are very high, the speaker cables
should conform to the following minimum requirements, otherwise the losses will cause the cables to get hot
and audio power will be reduced: D10 - 12A, D20 - 16A, D100 -20A - all into 4ohm speaker loads.
NOTE: Do not connect the inputs/outputs to any other voltage source such as a battery, mains source or power
supply, regardless of whether the amplifier is turned on or off. Do not run the output of any amplifier channel
back into another channel's input and do not parallel or series-connect an amplifier output with any other
amplifier output.
LINK SOCKET
Each channel is provided with a 3-pin XLR connector marked 'LINK' which allows the input signal to be linked to
further amplifiers etc. The connections are the same as for the input XLR.
BRIDGED (MONO) OPERATION
Use centre Speakon connector marked 'BRIDGED' and connect as follows:
HOT Pin +1 (Channel A - IN PHASE)
COLD Pin -1 (Channel B - OUT OF PHASE)
When operating in bridged mode, the minimum impedances are doubled. The minimum load in bridged mode
is: D-10: 4 ohms, D-20: 4 ohms, D-100: 4 ohms
E11EVEN SOUND \ D series amplifiers \ User’s Manual 9

Only D-100:
Additionally Channel A Speakon connector carries Channel B output on Pins +2 & -2 to allow easy bi-amping
or bridged operation using a single NL4 connector. Similarly, Channel C's Speakon connector also carries
Channel D output.
Output Connector A Output Connector C
Pin 2+: Hot Ch.B Pin 2+: Hot Ch.D
Pin 2-: Cold Ch. B Pin 2-: Cold Ch. D
For bi-amped operation, connect as above.
There must be no shared connections between channels.
Negative output terminals must not be joined together as they are not both at ground potential.
Connecting them together will damage the amplifier and void the warranty!
As the currents involved are very high, and to ensure best performance, the speaker cables should be kept
as short as possible and conform to the following minimum requirements (D-100, 20A into 4 Ohm speaker
loads).
When operating the amplifier into loads of less than 4 Ohms, be aware that the current capacity of the
speaker cables will need to be increased above the values quoted here.
Do not connect the inputs/outputs to any other voltage source such as a battery, mains source or power
supply, regardless of whether the amplifier is turned on or off.
Do not run the output of any amplifier channel back into another channel's input and do not
parallel or series-connect an amplifier output with any other amplifier output.
Pairs of channels may be independently bridged – channel pair A&B, and/or channel pair C&D.
The method is the same for both channel pairs:
Supply signal to Channel A or C input only and push in the appropriate rear panel switch marked “BRG A&B”
or “BRG C&D”.
Use Channel A or C's Output Speakon connector and connect as follows:
Pin 2+: Hot
Pin 1-: Cold
When operating in bridged mode, the minimum impedances are doubled. The minimum load in bridged
mode is 4 ohms.
Changing the Gain of Your Amplifier: Internal Adjustments!
These instructions are for use by qualified personnel only. Before any routine maintenance, please ensure
that your amplifier is disconnected from the mains supply!
Gain/Sensitivity Settings (D-100)
Adjustment is by moving a link on the input PCB (PCB741) – one link for each channel. Channel A's link is
number 1, channel B's is number 2 and so on. The gain may be set to 26, 32 or 36dB (factory setting).
10

Remember, setting higher gain does not change the maximum available power but changes the level of
signal input to achieve maximum power. In any case, provided that the input signal is less than 20dBu/7.7V,
the built in limiter circuit will prevent distortion within the amplifier.
The gain should be set to match the signal level from the source – mixer, equaliser etc.
Note: The gain of D-10 is fixed to 32dB. The gain of D-20 is 32dB (factory setting) or 36 dB by internal link.
