DESCRIPTION
EV power amplifiers of the PRECISION
SERIES meet the stringent requirements of
tough touring applications. They are protected 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 remarkable torsion resistance and is specially designed 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 circuits constantly compare the power amplifiers’ input and output signal and control the
limiters under non-linear operating conditions. They protect the loudspeakers from
overload due to power stage clipping. The
PRECISION SERIES power amplifiers feature excellent transmission properties. The
power amplifier topology also makes for
extremely low distortion rates. Distortion factor (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. Generously dimensioned power supplies with lowleakage toroidal-core transformers provide
considerable headroom well above the nominal ratings. V/I foldback limiter circuits
were deliberately not included in the PRECISION SERIES power amplifiers to facilitate 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 features.
The modes DUAL/Stereo or PARALLEL/Mono can be selected via the Input
Routing Switch. Furthermore, the PRECISION SERIES power amplifiers can also be
operated in “Mono Bridged” mode. The front
panel accommodates the dB-calibrated input
Gain controls which are designed as especially precise and safe-to-operate detented
potentiometers. The LED display provides
information about the power amplifers’ operating status. For the two channels, they
demonstrate readiness to operate, whether
there is a signal at the input or output, when
the Limiters have been activated and whether
one of the protective features has been
triggered. The power outputs Channel A,
Channel B and Bridged Out are available on
Speakon connectors. The rear side of the unit
accommodates the ON/OFF switches for the
integrated Hi and Lo cut filters, a groundlift
switch which separates the housing from the
circuit ground thus helping to prevent hum
loops and the operating modes selector to
mono bridged operation. They also feature
extremely quiet fans with front-to-rear airflow,
facilitating operation in large and narrow
amplifier racks.
# SERVICE INFORMATION
WARNING: No user serviceable parts inside.
Extremely hazardous voltages and currents
may be encountered within the chassis. The
servicing information contained within this
document is only for use by Electro-Voice
Authorized warranty repair stations and qualified service personnel. To avoid electric
shock DO NOT perform any servicing other
than that contained in the Operating instructions unless you are qualified to do so.
Otherwise, refer all servicing to qualified
service personnel.
NOTICE: Modification to Electro-Voice products is not recommended. Such modifications shall be at the sole expense of the
person(s) or company responsible, and any
damage resulting therefrom shall not be covered under warranty or otherwise.

WARRANTY STATEMENT
Electro-Voice products are guaranteed
against malfunction due to defects in materials or workmanship for a specified period, as
noted in the individual product-line statement(s) below, or in the individual product
data sheet or owner’s manual, beginning with
the date of original purchase. If such malfunction occurs during the specified period, the
product will be repaired or replaced (at our
option) without charge. The product will be
returned to the customer prepaid. Exclusions
and Limitations: The Limited Warranty does
not apply to: (a) exterior finish or appearance;
(b) certain specific items described in the
individual product-line statement(s) below, or
in the individual product data sheet or owner’s
manual; (c) malfunction resulting from use or
operation of the product other than as specified in the product data sheet or owner’s
manual; (d) malfunction resulting from misuse or abuse of the product; or (e) malfunction occurring at any time after repairs have
been made to the product by anyone other
than Electro-Voice or any of its authorized
service representatives. Obtaining Warranty
Service: To obtain warranty service, a customer must deliver the product, prepaid, to
Electro-Voice or any of its authorized service
representatives together with proof of
purchase of the product in the form of a bill
of sale or receipted invoice. A list of authorized service representatives is available from
