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.

O/P Load - 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 position.

'Infinity' control - Prime the unit before a take. Located in between each of the 6 recovery settings is the Infinity position which is, in effect, an extremely long recovery time. Place the compressor in one of the Infinity positions and have the artist play or sing a note before recording, then switching in the desired release time once things were under way. The Infinity setting prevents an increase in gain during silent passages. A quarter inch footswith jack on the rear allows for hands free operation.

Balance - 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.
