TUBE-TECH PA 6
STEREO HEADPHONE AMPLIFIER
General information
Sound quality in headphone monitoring has usually been the end of the line as far as studio
engineering is concerned. This is primarily due to the fact that amplification for this type of
monitoring is nearly always done with amplifiers that have been exclusively designed for
powering loudspeakers.
The TUBE-TECH PA 6 has been designed especially to be used with headphones and
providing the listener with maximum fidelity.
PRECAUTIONS:
THIS AMPLIFIER CAN PRODUCE VERY HIGH SOUND LEVELS.
CARE SHOULD BE TAKEN WHEN LISTENING TO HEADPHONES, AS YOUR HEARING
MAY BE DAMAGED WHEN EXPOSED TO HIGH SOUND LEVELS.
Design information
The output stage is designed around a dual power triode working in push-pull class A with a
adjustable bias and balancing circuit.
The input and driver circuit also uses dual triodes making the whole amplifier symmetrical from
the single ended input to the output.
All the voltages (except heater voltage for output and driver tubes) are fully stabilised.
Operating information
Several ways of operation are possible:
The TUBE-TECH PA 6 is used in the control room for high quality listening on headphones in
the same way as the various loudspeaker systems are used.
The TUBE-TECH PA 6 is used as the power amplification to drive the cue system in the studio.
Here the TUBE-TECH PA 6 replaces the customary power amplifiers used with most studio cue
systems.
In either case the objective of using the TUBE-TECH PA 6 is to substantially improve the
quality of sound in the headphones, thereby giving the listener a superior sonic experience.
