TCL · Overview
Introduction
The TCL is a unique analog thermo audio compressor featuring a superior natural
RMS detector and dynamic voice bass enhancement control. In another KV2 rst
its patented design oers an exceptionally musical and natural compression that is
a component part of its real-time input, rather than a typical side fed gain reduction
circuit attempting to either
follow or anticipate compression
demands. Its additional Bass
balance control circuit allows
the user to smooth out
and minimise any proximity
eects from a changing
microphone position, giving
the perfect voice color to every
performance, from beginning
to end. Featuring source intelligent
attack and release times, whatever
the dynamic content, with just
a few simple steps the results
from the 500 Series TCL are truly
exceptional.
Application
• The TCL is the ultimate
compression tool for various
studio and live applications
with instruments and voice.
• The TCL perfectly suits Musical
theatre - giving consistency,
richness and depth to head
worn microphones.
• The TCL is ideal for corporate

presentations - giving a full, warm, full voice timbre and allowing tone
matching for lecturn and lavalier microphones.
• The TCL can be used live on many musical instruments, both classical
and contemporary.
Controls
1) LIMITER
Serves to set the maximum input level. Any subsequent levels above the set level
are hard limited.
This ensures that any connected devices further down the signal chain are not
aected by an overloaded input The limiter’s active state is indicated by the limiter
LED.
2) DRIVE
This control sets the drive level for the input of the compressor’s gain reduction
circuit.
3) LOW
Serves as a low frequency enhancement circuit by rerouting some signal from
the second in line thermo-compressor through a low pass lter, providing a full
and warm bass enriched sound, even under compression.
Select the required bass enhancement by sweeping the pot in a clockwise
direction, where the center position presents a at frequency response,
with additional bass enhancement available beyond that point.
The combined output of its signal path after gain reduction and the bass
enhancement circuit blend, monitor and balance themselves perfectly
in real-time to maintain the all important voice color within a 20dB range.
Controls
4) LOW-MID Switch
This switch allows two alternate settings of the low pass lter frequency
in the thermo-compressor LF enhancement circuit. This can be set to the operators
preference depending on personal taste, microphone type and individual voice
characteristics. (Male / female etc)

5) OUT
Adjusts the output level.
6) METERS
Output level meter – a 12 segment, 3 color peak reading meter serves to monitor
the output signal level. If the red PEAK light ashes, the signal level is too high
and should be reduced to prevent possible overload distortion.
Gain reduction level meter – an 8 segment level meter displaying the amount
of gain reduction performed by the compressor.
7) BYPASS
Serves as a TCL module bypass.
Please Note - In bypass mode all meters and LED indicators will still show the lastest
operation mode, but the audio path is unaected by any of the settings.

QD8 · Overview
Introduction
A revolutionary George Krampera 8-band Equaliser specically designed
to highlight a desired band without adversely aecting the overall sonic landscape.
Whilst not intended for tuning out room modes, the frequency bands and lter
types have been precisely chosen after extensive research, to perfectly align
with the science of human hearing and our perception of achieving the ultimate
spectral balance. In a Live scenario,
faced with a number of dierent
sources, program types,
or performance genres
at a festival or concert,
the equaliser is very musical,
intuitive and an exceptionally
quick way to shape any mixed
content to the sound you want
to hear. In the studio, it can be
either the simple enhancement
of an instrument / vocal track,
or the nal mastering polish
to take an ordinary mix
and make it something very
special.
NOTE
As the QD8 is a stereo
(two channel unit) it will require
a series 500 Rack that facilitates
dual channel input and outputs.
It is also recommended to insert
the QD8 as the last unit
in the series 500 chain, directly
before the ampliers/speakers.

QD8 · Overview
Application
• For use in Recording Studios as a master equaliser, single instrument, or group
equaliser.
• Front of House PA system master equaliser, the unit is also equipped with line
drivers designed to maintain audio signal integrity over long cable lengths
(up to 200 m).
• Single stereo zone or dual mono system equaliser, to sonically match dierent
ll speakers and zones with the main FOH PA when used in multiples.
• To reduce the harshness in some digital recordings, particularly around
the 6kHz region.
Controls
1) 8-Band Equaliser
The Equalizer boosts or cuts frequencies at 40, 80, 120, 250, 500, 3000, 6000
and 15000 Hz by +/-15dB.
2) Output level meter
A 12 segment, 3 color peak reading meter serves to monitor the output signal level.
The signal should average around '0dB'. If the red PEAK light ashes, the signal level
is too high and should be reduced to prevent possible overload distortion.
Controls
3) EQ ON switch
8-band Equaliser EQ enable switch. When depressed, the EQ is bypassed.
NOTE
It is recommended to insert the QD8 as the last unit in the series 500 chain, directly
before the ampliers/speakers.
