User manual NAD 916

[. . . ] The multi-room output is not affected by the Volume or Tone controls (Treble, Bass) of the main system controls, so care must be taken to prevent auxiliary amplifiers being driven at full output level. If this appartus is not fitted with a UK three-pin plug, do not attempt to insert the attached plug into a UK mains socket. Instead, cut the plug from the mains lead and attach a fused UK three-pin plug using the following safety advice on wiring. The wires in this mains lead are coloured BLUE and BROWN; BLUE: NEUTRAL BROWN: LIVE The colours of these mains lead wires may not correspond with the coloured markings identifying the terminals in your plug. [. . . ] Such balance errors may be due to normal production-line differences in speaker sensitivity, differences in the acoustic environment around the two speakers, and slightly different distances from your chair to each speaker. You can use the input-level controls to correct these fixed balance errors, freeing your preamplifier's balance control to correct balance errors in recordings. Ideally the "phantom" central image should seem to be floating in mid-air midway between the left and right speakers. If it is located off-center, closer to one speaker, turn down the inputlevel control for that channel slightly in order to recenter the phantom mono image. Plug the AC line cord into a nearby wall outlet that provides the correct AC power line voltage, or into a switched convenience outlet on your preamp. Each of the three independent stereo power amplifiers within the 916 has its own pair of inputs and outputs. Before making connections to the amplifier, make sure the POWER is switched OFF. Connect the signal cable from the preamplifier, surround decoder or other signal source to these inputs. If you need fewer than six channels of amplification, see BRIDGING (# 6). This amplifier is equipped with special high-current binding-post speaker terminals to handle the highest peak power levels that may occur in the "bridged" mode or with low-impedance loudspeakers. ] (1) Strip off a half-inch (1 cm) of insulation from each speaker wire. Unscrew the knob, insert the bare wire into the opening at the base of the binding post, and tighten the knob until it grasps the wire securely. Check to be sure that no loose strand of wire is touching the chassis or an adjacent terminal. Or, (2) Install banana plugs on your speaker wires, and plug them into the end of each binding post. The terminals are separated by 3/4 inch (19mm), so they will accept dual-banana plugs. the Model 916 contains three separate stereo amplifiers - six channels in all. To use each pair as a conventional stereo amplifier, connect the wires from the left-channel speaker to the CH 1 + and CH 1 - terminals (or to the corresponding terminals on channels 3 and 5) and the wires from the right-channel speaker to the CH 2 + and CH 2 - terminals (or to the corresponding terminals on channels 4 and 6). NOTE - Stereo speakers must operate in phase with each other in order to produce a focused stereo image and to reinforce rather than cancel each other's output at low frequencies. [. . . ] to convert to bridged operation: (1) Select the two channels to be bridged. Connect its "positive" conductor to the CH 3 + terminal and its "negative" conductor to the CH 4 + terminal (i. CAUTION: In the bridged mode, wires must be connected directly from the amplifier to the speakers, not to a speaker switch, a headphone adapter, or any Cet appareil peut être posé sur n'importe quelle surface robuste, à condition qu'elle soit plane et horizontale. Om 916 används för att driva ett eller flera par extra högtalare till en stereoanläggning, skall förförstärkaren kopplas till ingångarna på NAD 916, dra sedan ett par kablar från linjeutgången på 916 till linjeingången på systemets huvudförstärkare.
