SPL Audio Volume 2 Stereo Volume Controller

Volume 2 is an active DAW monitoring controller and a puristic high-end preamplifier.

• High-end volume potentiometer and illuminated mute switch from ALPS; the potentiometer controls directly (no VCA or DAC circuits)
• The mute switch allows a quick reaction when speakers or ears need to be protected (e.g. in case of a computer crash)
• In contrast to digital volume control, where the bit resolution is continuously reduced as the volume decreases, the signal does not deteriorate with analog volume control.
• In contrast to passive volume control, active volume control does not affect the phase and frequency response. The monitoring signal sounds reliably the same at any monitoring volume.
• Balanced XLR input and output connectors
• High-quality balancing stages with very high common-mode rejection (minimizing interference/interference in the signal paths)
• High-quality power supply unit with toroidal transformer
• Solid aluminium knob with 45mm diameter for smooth, sensitive operation
• Elegantly designed and compact housing for flexible desk positioning close to the screen.
