iD4 amplifiers are fitted with Switched Mode Power Supplies (SMPS),
which significantly reduces the weight and size (only 2U) of the amplifier.
Using SMPS, the 2 symmetrical supply voltages of the power amplifier
are more stable than the power supplies used in conventional amplifiers.
The iD4 has been designed as a powerful two channel amplifier with on-
board 64 bit DSP processing. Both amplifier settings and DSP settings
can be user adjusted to match a speaker systems specifications. With up
to 100 onboard speaker pre-set storage capability, fine tuning of a system
or differing systems is fast, easy and strait forward; the user interface is
designed to be intuitive allow for quick familiarisation.
The combination of both power amplifier and on-board DSP technologies
used in the iD4, provide the level of control and audio quality expected
in any professional applications. The iD4, a very powerful and complete
speaker management system, with optimum flexibility and maximum con-
trol and security.
Since some of the externally mounted controls have multiple functions, it
is important that users should familiarise themselves thoroughly with the
entire range of controls.
