JOEMEEK reborn – the legend grows
The Next Generation of Joemeek studio processors represents a quantum
leap in the history of the Joemeek legend. Long regarded for its “Big Sound”,
the original Joemeek gear was both revered and reviled for its somewhat
“quirky” nature. Now we have taken the best of what made the Joemeek
products sound great, refined it, distilled it, added to it and repackaged it.
Properly and robustly engineered for predictable, controllable performance,
the new range retains the famous Joemeek sound, with its wide, flat frequency
response extending from subsonic to ultrasonic. It also uses genuinely low
noise circuitry, with lots of headroom (immunity to overload). Accurate cali-
bration and metering, together with clear panel labelling, give you complete
confidence in what’s going on. While some equipment pays lip-service to
quality and “professional rules” but fails to deliver, the Next Generation of
Joemeek products are founded on good solid electronic and audio engineering,
and withstand direct comparison with the very best names in mixers and
outboard gear.
The Joemeek range provides everything you need to get your performance
onto tape/disc.
About the Designer
The Next Generation of Joemeek has been completely re-engineered by
renowned audio electronics consultant Allan Bradford. With his background
in physics and 30 years experience with the design of instruments, mixers,
processors and amplifiers, Allan’s unique range of expertise ensures that
Joemeek remains at the forefront of music technology.

threeQ Controls at a Glance
MID - controls the middle frequencies in the audio spectrum. 15dB of
boost or cut is available at the selected frequency.
MID FREQ - sets the frequency at which the MID control operates,
anywhere from 300Hz to 5kHz.
HF - controls the volume of the High Frequencies or “Treble” in the
audio spectrum. 15dB of boost or cut is available around 12KHz.
EQ switch - turns the equalizer on. The LED lights when active.
OUTPUT GAIN - is the volume control or “Fader” for the outputs of the
threeQ.
VU METER - 8-Led bargraph shows the output signal level in dB at
any given moment.
48V PHANTOM POWER switch - when pressed in, feeds 48V phan-
tom power to the microphone XLR connector. Most condenser type
microphones require phantom power to operate.
+4dBu/-10dBv switch - selects the output operating level of the threeQ,
PREAMP GAIN - sets the amount of audio amplification. Too little gain
and the sound will be too quiet; too much and the signal could become
distorted.
PEAK LED - lights 6dB below clipping.
LINE switch - selects the Line (jack) input instead of the Mic (XLR) input.
The LED lights when active.
COMPRESS - sets the level of signal (or “Threshold”) above which the
signal starts to be compressed.
ATTACK - sets how quickly the compressor responds to peaks above
threshold.
RELEASE - sets the time during which the signal returns to its normal size
after compression. In general, the longer the time, the less obvious the
compression.
COMPRESSION METER - 4-Led bargraph indicates the amount of gain
reduction in dB, which is taking place at any given moment.
COMP switch - turns the compressor on. The LED lights when active.
either to the professional +4dBu level, or to the -10dBv semi pro level.
LF - controls the volume of Low Frequencies or “Bass” in the audio spectrum.
15dB of boost or cut is available around 80Hz.
