| For each
channel, use only one single XLR cable to operate both amps. Each amp now
operates in True Balanced Mode. The Positive and Negative signals are individually
amplified by an independent amplifier inside the SM-70 or SM-70 PRO.
The Output signals from each amp are then summed at the Positive and Negative Nodes of the amplifier. Voltage swing is now four times higher than in Stereo Mode. |
