Stereo Volume Controller with Transformerless, Electronically-balanced (Differential) Instrumentation Amplifier
SPL's Volume2 gives you a cost-effective alternative to the company's more full-featured monitoring controllers. This little fellow is dedicated to stereo level control. It has active circuitry to sidestep the inherent disadvantages of passive operation that result in impedance variation and the resulting frequency-response linearity degradation. In the studio, situate Volume2 between your playback machine's analog outputs and your monitoring for a direct, audiophile-quality playback path. Another great use for this nifty device is in your home audio system. However you use SPL Volume2, you'll be getting the purest monitor signal possible.
- Analog level control in the studio
- Perfect for your home audio system, too
Analog level control in the studio
If you're a DAW user, SPL's experience is that you can benefit greatly from analog level control. Most D/A converters are no help here; this means varying signal levels at the converter outputs. The result? A monitor signal with lowered bit rate - and the attendant loss of audio quality. SPL Volume2 to the rescue! For an audiophile-grade stereo playback chain, locate Volume2 between your playback machine's analog outputs, and your active speaker system (or power amp and speakers). This setup demands minimum financial and electronic effort and offers the most direct playback path possible.
Perfect for your home audio system, too
Another great use for Volume2 is in your home audio system. Your AV receiver uses VCA and DAC components which tend to produce distortions, and your signal usually runs through additional converters for volume control. This is especially true of SACD or DVD-A sources, where only direct, high-quality analog control of your source output guarantees an uncompromised playback of the original information.
