*4. This change can be made only if your amplifier has balanced inputs.
*5. This gain change applies in the typical case in which the amplifier has the same sensitivity/gain on both
balanced and unbalanced input connections. Some amplifiers have half the sensitivity on the balanced
inputs, in which case this connection change will result i n a +6 dB gain change. Please check the
specifications of your amplifier.
