The Quartet II
is not an update nor a replacement for our very popular Quartet,
but complementary unit that incorporates a substantially different
combination of elements. Designed with the input of Fletcher
of Mercenary Audio, many additional options have been provided
to tailor the texture of the audio character for maximum musical
The tube Mic/DI
preamp has the unique option of being able to switch between
two markedly different sounding input transformers and loading
options. The DI can handle pickups, keyboards, or line-level
signals. The mic preamp also features phantom power, input pad,
phase reversal, and a switchable lo-cut filter. Independent gain
and output controls permit overdrive of the tube stage to vary
the harmonic content of the preamp.
The delta-mu compressor,
derived from the popular ES-8, has the classic compression profile
of the Fairchild 660 and 670 limiters. It can be used in one
of five modes: Fast, Faster, Vintage (with program-dependent
response), Average (rms responding), or full manual operation.
It also features a switchable sidechain high pass filter to decrease
the sensitivity of the compressor to low frequency content.
The new 3 band tube
Passive/Aggressive Equalizer is a modern take on the classic
inductor-based passive EQ. It features simultaneous Lo Shelf
boost and cut, Mid Dip and Hi Peak bands. The Aggressive mode
increases the saturation of the EQ circuit to add harmonic content.
In addition, the EQ can be placed before or after the compressor
with the flip of a switch.
The new JFET/MOSFET
Peak Limiter uses a novel approach to brickwall analog limiting,
with JFET and MOSFET modes for two different characters of peak
limiting, and accurate led metering in 1 dB increments. Unlike
other designs, the peak limiter adds no appreciable distortion
