Volume 2

Stereo Volume Controller

The Volume 2 is a fully analog active stereo volume controller and a puristic high-end preamplifier.

High end volume potentiometer and illuminated mute switch from ALPS; the potentiometer controls signals directly (without VCA or DAC circuitry)
The mute switch allows for very fast reaction times in cases where loud speakers or ears should be protected (for example, with computer crashes)
In contrast to digital volume controls which reduce the bit resolution at lower listening levels there is no degration in sound with an analog volume control
In contrast to passive volume controls which alter the phase and frequency response there is no alteration in sound with an active volume control
Users of analog summing without monitoring facilities can cost effectively improve their systems
High quality balancing stages with extremely good common mode rejection minimize interferences and disturbances in the signal paths
Balanced XLR in- and outputs
A high quality power supply with toroidal transformer
Massive, 45 mm diameter aluminum knobs ensure consistent, refined handling
The elegant, compact housing allows for flexible desktop positioning near or under a computer monitor.
Made in Germany
