Unity Gain 89 VeniceU Operator Manual Unity Gain Unity gain is a gain of 1, that is, no gain or attenuation is applied to a signal. If a signal entered a mono line level input of the Venice U at 0dBu and the gain was set to +10dB (an internal 10dB attenuation sets the net gain to 0dB), then the signal was routed to each output at 0dB, the channel f[...]

90 Appendix C: Application Note s VeniceU Operator Manual There are a number of solutions to this problem: • Reduce the amplifier’s input attenuat or s to a level where the amplifier and console clip at the same point.
