The inputs of this power amplifier may be used as signal pass connections to daisy-chain multiple amplifiers.
Devine does not recommend linking more than three D-series power amplifiers in a daisy-chain setup so as
to prevent any loss of signal level and quality.
WARNING!
Do not send two signal inputs to the amplifier at the same time! The combination of two signal
inputs will exceed the signal of the preamp section of the amplifier. Improper use of the inputs may cause
loss of quality or even permanent damage to the amplifier.
Ground lift option
The ground lift option is used to remove the ground connection of any incoming balanced input signal. This
may help to remove noise caused by a flowing current in the ground shield. Usually, this is caused by un-
earthed equipment which is connected to the chain, or the use of different power circuits. Make sure all your
audio equipment is connected to the same grounded power circuit. Do not use ground lift when it is not
necessary to ensure optimal signal quality. The default setting on your power amplifier should be set to
'Ground'.
WARNING!
Please be aware that removing the ground shield of your equipment may be dangerous. The
ground shield of your signal inputs makes sure that excessive currents are eliminated and removed through
the ground shield. Removing the ground shield increases the risk of (hazardous) electrical shocks on
conducting materials such as metal microphone housings.
Output section
The rear of the D-series amplifiers is equipped with a clearly
marked speaker output section. These outputs can be connected
to the inputs of passive speakers or subwoofers (correct usage is
explained in the section
Crossover information on Subwoofers
in this user manual).
The output section of the amplifier makes use of speaker-lock
connectors (two black connectors, one red connector).
Speaker-lock
The black speaker-lock connectors are used for regular speakers in a standard stereo setup and are
compatible with similar products by many manufacturers. These connectors are used for mobile use when
the connectors are inserted and removed frequently. To connect one of these plugs, insert the connector into
the speaker-lock chassis and turn it clockwise. You will hear a 'click' sound, which means that the connector
is locked in place and connected perfectly.
This kind of connector is usually equipped with 4 pins (2-pin versions are available as well), divided into +1/-
1 and +2/-2. All D-amplifiers outputs are wired at +1/-1 for each channel.
The red speaker-lock connector
is used for
Bridge mode
, but is technically identical to the black speaker-
lock connectors.
The Bridge output makes use of two amplifier channels and combines its power to one signal output. This
makes it possible to use all of the power from one D-series amplifier to drive one full range speaker or
subwoofer (correct usage is explained in the
Bridge mode
section of this user manual).
The Bridge output is also wired at +1/-1.
Bridge mode
The Devine D-series amplifiers are equipped with a switch to activate Bridge mode. Also, the output
connectors of the amplifier are prepared for Bridge mode setups. Bridge mode makes it possible to combine
the power from two channels on one amplifier to provide sufficient power for one large speaker or subwoofer
(correct usage isexplained in the
Crossover information on Subwoofers
section of this user manual). This
way, one single power amplifier provides sufficient power for one speaker, where in normal setups, two
speakers would be connected to one power amplifier. To use Bridge mode, the switch which is set to
Stereo
mode
by default needs to be switched to
Bridge mode
. Both stereo and mono inputs can be connected to the
amplifier.
