As a cost-effective alternative to SPL's full-featured Stereo and Surround Monitoring Controllers MTC 2381 and SMC 2489, the SPL volume controllers are dedicated solely to level control.
The Volume2 model is intended for stereo applications, while the Volume8 can control up to 8 channels. Both devices are designed with active circuitries to circumvent inevitable disadvantages of passive circuitries that result in impedance variation and therefore degraded linearity in frequency response.
SPL Volume 2 Key Features
High quality balancing stages with extremely good common mode rejection minimize interferences and disturbances in the signal paths
The mute switch allows for very fast reaction times in cases where loud speakers or ears should be protected (for example, with computer crashes)
Users of analog summing without monitoring facilities can cost effectively improve their systems
