V-Scale Variable Buffer (Dark Edition)

Precision Buffered Multiple, with Individual Output Trimmers

This is a precision active buffer and multiple. This module has outstanding performance: it features very high input impedance, very low output impedance and an offset voltage of 1mV.

Not all active multi’s are born equal, some designs do not fully solve impedance mismatch and tracking problems ..or they apply offset voltages to the output and in rare cases can cause more problems than they solve!

AJH Synth have added a very useful (and unique) feature to cure tracking problems: four of the five outputs can be adjusted up or down by +/-5% from the front panel, so that VCO’s and VCF’s that don’t track 1V/Oct exactly can be easily compensated to track correctly without having to re-calibrate the VCO or VCF themselves.
