This is a precision active buffer and multiple with outstanding performance, featuring very high input impedance, very low output impedance, and an offset voltage of <1mV.

Not all active multiples are created equal; some designs do not fully resolve impedance mismatch and tracking issues. This may be because their input impedance is not sufficiently high, or the output impedance is not sufficiently low, or perhaps a combination of both. Additionally, they may apply offset voltages to the output that cause a pitch difference when the buffered multiple is connected or disconnected, which in some cases can cause more problems than they solve!

Besides being a very accurate precision buffered multiple, we have added a very useful (and unique) feature to fix tracking problems – four of the five outputs can be adjusted up or down by +/-5% from the front panel, so that VCOs and VCFs that don’t track 1V/Oct exactly can be easily compensated to track correctly without needing to recalibrate the VCO or VCF themselves.

Available with either silver or black front panels.
