Der Amtec PEQ-10 ist ein Update des bereits bekannten Amtec PEQ-1A
Equalizers im Mono-Pultec-Style. Neu ist ein 10KHz Shelving on neue
Peak-Frequenzen im HF-Boost-Band, gerasterte Potis, neue Innenkomponenten und
ein verstärktes Chassis.
The PEQ-10 is a 2U-high mono tube unit based on the
Pultec EQP-1A. This is however not a faithful copy of the original, but rather
an improved version which, besides increased abilities, preserves the sonic
quality of incoming signal.
Simple at first sight the equalization
section is in fact very flexible giving you the tool to powerfully shape
tonality without side effects. With the low frequency section you can boost bass
without muddying the low mids, and the high frequency section can add sheen and
"air" in an almost exciter-like fashion, but with much more natural results.
Introduced warmth in the bottom end and sparkle in the treble give individual
tracks and entire mixes more depth, punch, presence and clarity.
PEQ-10 consists of a passive equalizer that is coupled to a tube amplifier
restoring the gain. The passive circuit uses inductors and capacitors to achieve
equalization giving the most musical results and the least distortion possible.
The gain recovery amplifier is unique in several respects. It uses commonly
available tubes in a high-voltage, feedbackless push-pull circuit coupled to
specially wound output transformer which provides balanced and floating
Another improvement is increased input impedance. A lot of
contemporary equipment cannot drive the traditional 600 ohms load sufficiently.
The PEQ-10 has input impedance more than 3 times higher, thus it doesn't load
down the output of the preceding device.Very gentle equalization curves make
Pultec-type EQs sound very musical. This device is not an exception.
equalizer has a low frequency shelving boost and attenuation, which can be used
simultaneously for special effects, as well as a peaking high frequency boost
with variable bandwidth and a high frequency shelving attenuation.
the make-up amplifier, it uses a configuration that has intrinsic high bandwidth
and linearity, and does not need feedback to improve them. As a result you end
up with minimum transient distortion. It also gives more open and effortless
sound. The bypass switch omits equalization section leaving tube amplifier in
the signal path. The power supply has full regulation of the +B and heater
voltages. Each unit is hand-build with great attention to
Despite having old-style features, the PEQ-10 is very versatile
and is perfectly adequate to modern recording techniques. With new frequencies
it became yet more flexible than the original. This is the ultimate equalizer to
make silky smooth enhancements to vocals, bass, drums and complete mixes, but
all of the other sources would benefit as
