ZRS C3
The ZRS C3 is classified as an unbalanced power amplifier. This means that the power of channels 1 and 2 is not equal to the power of
channels 3 and 4. Though a 4 channel amp, its purpose and design was to deliver optimum 3 channel system performance. Channels 3 and
4 are more powerful than channels 1 and 2 and thus designated for either the subwoofers in a system or for multiple mid-bass drivers. All
channels are 1 ohm stable in stereo mode and may be bridged to a 2 ohm mono load.
UNBALANCED 4 CHANNEL AMP
Two 4-Ohm Subwoofers wired in parallel to each channel will equal a 2-Ohm stereo load.
