Your dealer is responsible for making sure that the system sounds exactly as it should and information given here is not intended to reduce this responsibility in any way. 5 8 12 15 18 20 1. 1 cables and connections 2. 0 Getting Started 2. 1 switching on and off 2. 2 running in 2. 3 mains supply 2. 4 siting the equipment 2. 5 if you have a problem 3. 0 Warnings 4. 0 Connection 4. 1 mains lead 4. 2 non-rewireable mains plugs 4. 3 fuse carrier 4. 4 plug fuses nac 52 nac 82 nac 102 nac 112 narcom 2 remote handset EC Declaration of Conformity to Appropriate Standards 1. 1 cables and connections Please do not modify the standard interconnect cables supplied with your Naim equipment. One end of each cable is marked with a band to establish its correct orientation. Naim loudspeaker cable is correct for your system and your dealer will make up leads to suit your equipment installation.

It must be used in conjunction with either a naim power amplifier incorporating a preamp power supply or with a supercap, hi-cap or flatcap 2 power supply. listening and recording The input selector buttons are arranged along the uppermost bank of buttons. They control which source is to be routed to the power amplifier and the loudspeakers, for listening. Below them, in the lower bank, are a corresponding array of buttons which choose the source component to be routed to the preamplifier's recording outputs. One component (for example, the record player) can therefore be listened to whilst the output from another (say, the tuner) can be recorded onto a tape recorder. It is possible to lock the record controls and prevent accidental de-selection during recording. Record-lock is switched on or off by depressing the source mono button four times within six seconds. mute and mono facilities To the left of each bank of buttons there are two further buttons labelled mute and mono. These work independently: for example the mute button in the lower (recording) bank does not affect the signal that is chosen via the upper (source) buttons, and vice versa. Operating the mono button on the source bank will not affect the record circuits. To cancel that function press the button again. preamplifier inputs Input 1 is a high level input, but can be converted into a phono input by fitting plug in boards. Inputs 4, 5 and 6 are standard high level inputs and also have record output facilities, so these should be assigned to your tape recorder, cassette deck or VCR. connecting to an active system Please note, an additional separate power supply is required to power the snaxo crossover, i. e. three hi-caps for a system where two are already employed to power the nac82, or two supercaps where one is already employed for the preamplifier. For further information please refer to your dealer. remote control For operation of the nac 82 using the NARCOM 2 remote handset please see pages 18 and 19. bnc plugs For notes on wiring bnc plugs please see page 7. 8 nac 82 front inputs 1 2 3 4 5 6 source record mute volume balance mono nac 82 rear high level inputs outputs 6 5 4 3 2 phono input 1 napsc ch 1 left ch 2 right phono ground inputs 3 & 2 nc nc inputs 6, 5 & 4 ch1 ch2 ch 2 -ve ch1 ch1 ch 2 -ve Specifications nac 82 Line input sensitivities Phono input options Moving Magnet N Moving Coil S Moving Coil K Moving Coil E Overload margin (all inputs, all audio frequencies) Main output level Tape output level Case size (H x W x D) 75mV, 100k 2mV, 47k 100µV, 470 100µV, 560 400µV, 560 40dB 0. 775V, <50 75mV, 600 76 x 430 x 300mm 9 nac 82 connection to one power amplifier with internal power supply all link plugs fitted to napsc to nap 140, 150, & 180 power amplifiers note The napsc power supply must be connected at all times to the nac 82. nac 82 connection to one hi-cap (or flatcap 2) link plug fitted link plug removed to napsc to nap 140, 150, 180 & 250 power amplifiers to nap 135 & 500 power amplifiers mains input 10 nac 82 connection to two hi-caps (or flatcaps) all link plugs removed to napsc mains input to nap 135 & 500 power amplifiers to nap 140, 150, 180 & 250 power amplifiers mains input note If multiple power supplies are used to operate one preamplifier they must be of the same type.

It must be used in conjunction with either a naim power amplifier incorporating a preamp power supply or with a supercap, hi-cap or flatcap 2 power supply. preamplifier inputs Inputs 1a, 2 and 3 are standard high level inputs. Inputs 4, 5 and 6 are standard high level inputs and also have record output facilities, so these should be assigned to your tape recorder, cassette deck or VCR. tape facilities and monitor button The tape monitor button (mon) allows you to listen to the output of a tape recorder while recording, which can be useful with a 3-head tape machine to monitor the "off-tape" signal. Operating the monitor button during recording allows the output from the tape machine connected to input 4 to be heard, unless input 4 is chosen on the input selector switch, i. e. for tape to tape recording, in which case the output of the tape machine connected to input 5 will be heard. With the mute button selected there will be no output to the loudspeakers, from any input. This will not affect any recordings taking place at the same time. remote control For operation of the nac 102 with the NARCOM 2 remote handset please see pages 18 and 19. Note: As there is no mono facility available on the nac102, the "mono" facility on the remote handset operates the tape monitor circuit. bnc plugs For notes on wiring bnc plugs please see page 7. 12 nac 102 front inputs 1 2 3 4 5 6 mute volume balance monitor nac 102 rear outputs high level inputs phono input 1b 6 5 4 3 2 1a napsc (optional) ch 1 left ch 2 right phono ground inputs 3, 2 & 1a inputs 6, 5 & 4 ch1 ch2 -ve ch1 ch 2 ch1 ch 2 -ve nc nc Specifications nac 102 Line input sensitivities Phono input options Moving Magnet N Moving Coil S Moving Coil K Moving Coil E Overload margin (all inputs, all audio frequencies) Main output level Tape output level Case size (H x W x D) 75mV, 100k 2mV, 47k 100µV, 470 100µV, 560 400µV, 560 40dB 0. 775V, <50 75mV, 600 76 x 430 x 300mm 13 nac 102 connection to one power amplifier with internal power supply link plugs fitted napsc (optional) to nap 140, 150, & 180 power amplifiers nac 102 connection to hi-cap (or flatcap 2) link plugs removed napsc (optional) to nap 140, 150, 180 & 250 power amplifiers to nap 135 & 500 power amplifiers mains input note When using a hi-cap without the optional napsc, the large link plug must be fitted. cable direction marker Interconnect Cables 4 to 4 pin DIN 5 to 5 pin DIN 14 nac 112 operation power supplies The nac 112 does not incorporate an internal power supply. It must be used in conjunction with either a naim power amplifier incorporating a preamp power supply or with a supercap, hi-cap or flatcap 2 power supply. inputs The nac 112 has 6 inputs - cd, tuner, tape, A/V, aux 1 and aux 2. [. . . ] To access automatic source switching enter program mode as described above. The mon button on the amplifier will illuminate when source switching is automated. To utilise the surround sound processor unity gain function, enter program mode as described above. The mute button on the amplifier will illuminate when unity gain is selected. [. . . ]
