VCM Hi-End MUSES® Mini Volume Control Board


Hi-End MUSES®  Mini Electronic Volume Control board VCM is a complete ready to use two channel volume control unit that requires a power supply and control signals to operate.


The unit is built using a unique NJR MUSES®72320 volume control chip.  The same chip was used by legendary Nelson Pass in his highly acclaimed XP-30 line preamplifier.  Unlike other electronic volume control chips, this chip does not  include any active circuitry, and therefore provides vanishingly low level of noise and distortions.  The performance of the entire volume control system is completely dominated by the quality of an opamp or a buffer (if no gain is required) that follows the MUSES® volume control chip.


A MUTE relay control signal is provided to eliminate any unwanter noises  from power-up/power-down processes.Refer to the Specifications section for complete product specifications.


The control signals format and power requirements can be found in the MUSES®  chip specification in the Downloads section
