About this listing
The SPL Volume 8 8-Channel Volume Controller is a fully analog, 8-channel volume controller and a puristic surround preamplifier, that focusses on analog monitor leveling an sports a Mute switch that in case of a computer crash protects your speakers, headphones and ears. The SPL Volume 8 8-Channel Volume Controller's advantages become especially apparent in combination with DAW based audio and video production systems. When changing the volume in the DAW the converters will be operating at a lower bit rate. 6dB reduction of the monitoring level is equivalent to 1 Bit less resolution. We are monitoring on an average of -24dB to -36dB below 0dBfs which means that the bit resolution is diminished by 4-6 Bits. With the Volume 8 this does not affect you. It uses a high quality 8-gang potentiometer to control in the analog domain. The SPL Volume 8 8-Channel Volume Controller circuitry is an active design rather than a passive one. For a very good reason. When changing the volume in a passive design the impedance change affects the phase and frequency response negatively. An active design is therefore much more accurate and the far better solution. SPL Volume 8 8-Channel Volume Controller Features High end volume potentiometer and illuminated mute switch; the potentiometer controls signals directly (without VCA or DAC circuitry) In contrast to digital volume controls which reduce the bit resolution at lower listening levels there is no degradation 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 High quality balancing stages with extremely good common mode rejection minimize interferences and disturbances in the signal paths Balanced DB25 input and output connectors (Tascam-Standard) High quality balancing stages with extremely good common mode rejection minimize interferences and disturbances in the signal paths 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.
