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.
