As a cost-effective alternative to our 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.

 

Additional reasons to employ the Volume2

  • 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

Special Features

The Volume2 is built only with analog circuitry and performance, and its high quality parts in sophisticated circuitry design are prerequisites to superior audio quality:

  • High end volume potentiometer and illuminated mute switch from ALPS; the potentiometer controls signals directly (without VCA or DAC circuitry)
  • Balanced XLR in- and outputs
  • A high quality power supply with toroidal transformer
  • Massive, 45 mm diameter aluminum knobs ensure consistent, refined handling
  • The elegant, compact format housing (215 x 80 mm or 8.5 x 3.1 inch) allows for flexible desktop positioning near or under a computer monitor or generally saving space in positioning

Unbalanced connections, e. g. to and from RCA or TS Jack

You can establish unbalanced connections easily and without adaptors – for example from CD-Players with RCA outputs or to (HiFi) power amplifiers with RCA inputs. In any case we recommend to use readily configured cables from XLR to the respective RCA or TS/TRS connector to dispense with adaptors. Ask your dealer for configured cables. It is important to pay attention to the correct polarity of the three XLR wires. With the XLR pin configuration diagram in our manuals any audio expert can ensure to select or configure appropriate cables.
