DESCRIPTION
EV power amplifiers of the PRECISION
SERIES meet the stringent requirements of
tough touring applications. They are protec-
ted against over-temperature, overload,
shorted outputs, radio frequency interference
and DC faults. The power transistors are
protected from damage from reverse feeding
of electrical energy by means of an additional
special protective circuit. For the so-called
soft-start, the power outputs are switched on
delayed via relays. An inrush current limiter
circuit prevents the mains fuses from being
blown.
Maximum precision is also guaranteed as
regards mechanical construction and finish.
The robust steel chassis features remarkab-
le torsion resistance and is specially de-
signed to cope with the tough wear and tear
associated with going on tour. Thermal
stability is guaranteed by several low noise
3-stage fans which also means that they can
be used inside the studio.Comparator cir-
cuits constantly compare the power ampli-
fiers’ input and output signal and control the
limiters under non-linear operating conditi-
ons. They protect the loudspeakers from
overload due to power stage clipping. The
PRECISION SERIES power amplifiers fea-
ture excellent transmission properties. The
power amplifier topology also makes for
extremely low distortion rates. Distortion fac-
tor (THD), intermodulation distortion
(SMPTE-IM) and transient intermodulation
distortion (DIM 30 and DIM 100) are so low
that they are only detectable with the most
sophisticated measuring equipment. Gene-
rously dimensioned power supplies with low-
leakage toroidal-core transformers provide
considerable headroom well above the no-
minal ratings. V/I foldback limiter circuits
were deliberately not included in the PRE-
CISION SERIES power amplifiers to facilita-
te operation at complex loads up to a phase
angle of +/- 90°.The inputs are electronically
balanced on XLR connectors. (Isolation
transformers can be retrofitted). Direct Outs
in the form of XLR connectors (male), to loop
the signal through, are also standard featu-
res.
