SPL Volume2 Stereo Volume Controller
Actively Analogue
Volume2 is a dual-channel stereo volume control powered by active circuitry. Unlike alternative passive technologies which can invoke impedance variation and frequency response linearity problems, the Volume2’s active route ensures that signal passes from interface or source to studio monitor unscathed and with healthy professional-grade headroom to spare.
Bit-Rate Friendly
Whilst many modern audio interfaces feature volume controls that adjust levels by dropping dBs at the converter stage, this often also leads to a drop in bit-rate making monitoring at low levels accurately a challenge.
By situating Volume2 between interfaces and studio monitors, volume attenuation can be handled purely in the analogue realm maintaining bitrate at a comfortably high level whilst mixing at any volume.
Home Audio Applications
Volume2 can also be used for home audio systems. Home audio components such as AV receivers often use VCA or DAC components that pick up a certain level of distortion between stages. As with studio monitors and interfaces, Volume2 can be interposed between the source and output stages to ensure a purely analogue level control and avoid any distortion gathering pace.
