1There is one CHANNEL trimmer per amplifier channel. Each trimmer will attenuate each input from a minimum to MAX setting (approx - 13 dB to 0.0 dB). We have designed the adjustment range sufficient to match the speaker sensitivity both from room-to-room and per speaker for multi-speaker installations. The design of this trimmer is for sensitivity matching only, not a volume control. It is highly unlikely one would adjust the trimmers once the installation was complete, thus for this reason we have placed the trimmers at the back of the amplifier.

2Each amplifier CHANNEL INPUT OUTPUT is a direct pass-through connection, thus the source impedance of each channel input is exactly the impedance of the output. The special design of the NAD RCA cables that accompany the NAD CI-series amplifier allow for up to 6 channels to be fed from one channel of the Flex-Pad STEREO and MONO OUT, without degradation in sound quality. For example, one can jumper from Flex-Pad OUT Right to CHANNEL 1 INPUT, then from CHANNEL 1 OUTPUT to CHANNEL 2 INPUT, from CHANNEL 2 OUTPUT to CHANNEL 3 INPUT, and so on up to 6 channels of inputs. The NAD CI-series RCA jumper cables are specially designed low-capacitancehigh-performance cables. We do not recommend that you use any other RCA jumper cables than the NAD RCA jumper cables supplied with the NAD CI- series amplifier, to do so may cause significant loss in music fidelity or possible other problems.

3The Flex-Pad MONO OUT is a sum of the stereo right and left inputs with an output impedance of 75 ohms. We do not recommend driving more than 6 amplifier inputs with this MONO OUT source.

4The Flex-Pad STEREO right and left OUT is a stereo buffer with an output impedance of 75 Ohms per output, capable of driving up to 6 NAD CI-series amplifier inputs per output. We do not recommend you drive more than 6 amplifier inputs per Flex-Pad output.

5The Flex-Pad STEREO right and left IN is a high-impedance input specifically designed for connection to preamplifier or home-theatre processor outputs. We strongly recommend that these inputs not be connected to equipment that does not have a volume control!

6The VACATION switch is the master on/off control for the amplifier. When the switch is in the on state the amplifier is in standby as shown by the amber LED above the power switch on the front panel. If the amplifier will not be used for an extended period of time, switch the VACATION switch to the VACATION position.

7The SLEEP/WAKE, SENSE/DEFEAT switch logic controls the standby/on-state of the amplifier via the presences or absence of audio signal at the Flex-Pador amplifier channel inputs. The SLEEP/WAKE, SENSE/DEFEAT switch must be in the SLEEP/WAKE position in order to use this logic. When the SLEEP/WAKE, SENSE/DEFEAT switch is in the SENSE/DEFEAT position, this logic control is deactivated.

When the switch is in the SLEEP/WAKE position, the NAD CI-series amplifier will instantaneously turn on from a standby state, sensing any input signal from any channel as seen by a lit green SENSE LED on the front panel of the amplifier (approximately above 20mV RMS input). If all of the audio signals are absent for approximately 5 minutes, the amplifier will switch automatically to standby condition, with the green SENSE LED off, and the amber LED over the front panel switch lit.

When the switch is in the SENSE/DEFEAT position, the amplifier will not turn on even if an input signal is present on any channel or Flex-Padinput.
