The Lisson Grove - AR-1 Tube Compressor
The Lisson Grove AR-1 is a vintage style tube compressor based
on the classic Altec compressor that was used intensively in the '60's.
However, the AR-1 has some modifications. Some of which are
in the circuit and some functional. The quality of each component in the units is of the highest possible standard, and the unit is hand built from top to bottom
The Lisson Grove AR-1 has been built from a love of the sound
of a bygone era . We hope you recognize that very familiar sound.
15ms to 130ms
Also self explanatory, but if you pull the pot the compression is
bypassed, it is not a hard bypass, and you retain the sound of the
unit without the compression.
This Pot adjusts the output impedance of the unit going from 600
ohms in the far right position, to 200 ohms ( Dark ) in the far left
We put this on our unit as the original had an output of 200 ohms
but we felt that was too dark for some uses so made it possible to
have a variable tone without adding anything to incongruous
to the circuit.
The 'Infinity' control
In between each of the 6 recovery settings is the Infinity position
which is, in effect, an extremely long recovery time.
There are a variety of uses for this feature, a useful one being the
ability to 'prime' the unit before a take. This is done by placing the
compressor in a 'Infinity' position ( one click up or down from the
desired setting ), having the artist play or sing a note before
recording, then switching in the desired release time once things
were under way.
Yet another use of 'Infinity' would be to prevent an increase in gain
during silent passages. We have also added a quarter inch jack on
the back, to enable a footswitch control, for hands free operation.
This provides an easy way to balance out the two sides of the gain reduction valve, thus minimizing distortion and feed-through thumps. When you press the push-button,it is then a simple matter
for the engineer to adjust a small trim control until the pulsing
sound is heard at its lowest level. This is a very practical for balancing out the gain reduction valve.
"I love the Lisson Grove AR-1 . It's rare to find a new compressor that has the bounce and character of a 'classic' vintage unit but also the reliability of a new one. I have found it to be a very musical tool for mixing but also a great creative tool when I'm after something more adventurous.. the perfect thing to turn to for bringing life and edge to sounds. It cooks!"

"Today I put the AR-1 on the vocal, yesterday I put it on the acoustic and the day before I put it on the bass. If i'm gonna spend good money on a compressor it can't be a one trick pony. There's a few ponies running around in this baby."
