ATTENTION: INSTALLATION PERSONNEL

The mounting hardware was specifically engineered for the NAD CI-series amplifier. We recommend that you do not substitute the mounting hardware.

Due to the high-power capability of the NAD CI-series amplifier, the power supplies are heavy and may require more than one installation person to rack-mount the amplifier.

NOTE

The amplifier's weight must always rest on its bottom feet when placed on to a surface. Never put the amplifier down on its rear panel, with its front panel facing up. Doing so risks damage to the input/output connectors.

The amplifier generates a moderate amount of heat, requiring internal ventilation. Do not permit the air inlet and outlet grilles on the top, bottom, side, and back cover to be obstructed by papers or other materials.

NOTE

To prevent a fire or shock hazard, do not permit liquid or moisture to enter the amplifier. If liquid is accidentally spilled on it, immediately shut off the power and unplug the AC Mains cable from the wall outlet.

Do not open the amplifier or attempt to modify or repair it yourself. Refer all servicing to a qualified technician.

NAD ATO LOGIC

The CI-series amplifier may be turned on in any one of three discrete ways for complete system flexibility: From the front-panel switch, the 12V-TRIGGER circuit, or by a "SLEEP/WAKE" signal-sensing circuit. The ON/OFF power control is managed by the Automated Turn-On logic or ATO Logic circuit that requires the amplifier to be switched back to standby in the same manner by which it was activated. In other words, if the amplifier is switched on via a 12V-control signal, it cannot be switched to standby via the front-panel switch, it must wait for removal of the 12V-control signal. In practice, you probably would use only one of the methods once the NAD CI-series amplifier is installed.

NAD OMC

NAD's proprietary Output Management Circuit (OMC) ensures that the full power is available at any reasonable load impedance. The OMC controls individual amplifier channels by managing the input level, in case of deliberately excessive input signal, and/or output level, in case of speaker or speaker cable fault. This not only protects the amplifier, but it also prevents loads attached to the amplifier from heating up excessively, an important factor when the reliability of an installed system is a consideration. When the OMC detects a potential fault situation and begins to limit current flow, an amber-coloured LED illuminates on the front panel to alert the installer/owner of a problem in the system. When the OMC is activated, the amplifier will continue to play without distortion, but the power level will be reduced to the amplifier channel that has the problem. If the fault condition persists and the impedance becomes too low the affected channels will initiate the NAD Protection Circuitry (see NAD Protection Circuitry below).

NAD PROTECTION CIRCUITRY

Every design decision, both electronic and mechanical, was made with absolute reliability of the amplifier as the primary goal. An auto-resetting protection circuit is also part of the CI-series amplifiers' design. The fast acting protection circuit jumps into action if the amplifier overheats or encounters a short circuit condition. A red front-panel LED indicates that the Protection circuit has been activated. Only the amplifiers being affected by a short circuit condition will be in the protection mode; all other channels will continue to play normally. When the condition is normalized the affected channels reset. In the unlikely event of amplifier failure, the CI-series amplifier is designed to be easily field serviceable with all amplifying circuitry mounted on plug-in modules.

REAR-PANEL CONTROLS AND CONNECTIONS

1 There 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.
2 Each 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 allows 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-capacitance high-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.
3 The 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.
4 The 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.

5 The 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!
6 The 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.

7 The 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-Pad or 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-Pad input.

8 The 12V TRIGGER IN and OUT connectors are 3.5mm monotype miniature phone jacks, with the centre pin of each serving respectively as a 12V signal sensor and 12V signal driver. We recommend that you use a good quality cable with shield when attaching the 3.5mm monotype plugs so as to prevent false triggering of the amplifier due to electro-magnetic interference from nearby electronic equipment. The 12V-IN TRIGGER allows you to have an external 12V signal turn on the NAD CI-series amplifier from standby. This 12V signal must be a continuous 12V signal in order to keep the amplifier in the on state. Once you remove the 12V signal the amplifier will return to standby. The 12V-OUT TRIGGER allows you to control other products with a 12V sensor, by the NAD CI-series amplifier. The 12V-OUT TRIGGER is constantly present when the NAD CI-series amplifier is in the on state, and absent when in standby or VACATION state.

NOTES

• Check the specifications of the trigger input terminal on the other components to ensure these are compatible with the NAD Cl-series amplifiers.
• All 12V-TRIGGER inputs and outputs on other NAD components with a 12V-TRIGGER feature are fully compatible with the NAD Cl-series amplifier's IN/OUT 12V-TRIGGER.
• Before making any connections to any 12V-TRIGGER input or output, make sure all components are disconnected from the AC mains.
• If in doubt over the connections, installation and/or operation of the IN/OUT 12V-TRIGGER connections consult your NAD dealer or sales representative.
• Failure to observe the above may result in damage to the NAD Cl-series amplifier and/or any ancillary components attached to it.

9 There is one set of speaker terminals per amplifier channel. They are marked "+" and "- to indicate their polarity.
10 There are two discrete-types of AC-power cords. Refer to figures below for the type that relates to your NAD CI-series amplifier:

Before connecting the AC-power cord to a live wall socket insure that all inputs/outputs are connected first. Always disconnect the AC-power cord plug from the live wall socket first, before disconnecting any cable from the CI-series amplifier. If you must use an extension cord, select a heavy-duty cord of the type used for large electrical appliances, such as an air conditioner AC-extension cord (16 AWG). We strongly recommend that you not connect the amplifier's mains cable to the accessory AC outlets on a preamplifier. Such convenience outlets are not designed to supply the high-power levels that the NAD CI-series amplifier requires.

11 There is a fuse holder nearby or next to the AC-line cord. In the unlikely event a fuse may need to be replaced, unplug the line cord form the wall. Then remove all connections from the amplifier. Only replace the fuse with the same type, size, and specification. Refer to "SPECIFICATIONS, NAD Models CI 9060 and CI 9120" at the back of this instruction manual for the correct number, type and size of the replacement fuse.

CAUTION

Failure to replace the fuse with the correct number, brand name, and type listed in the "FUSE REPLACEMENT - PLEASE NOTE CAREFULLY" chart, found in the back of this instruction manual under section "Fuse Replacement Chart" will eventually lead to either another blown fuse or amplifier damage.

FRONT-PANEL CONTROLS AND INDICATORS

1 The amber standby indicator LED over the front power switch must be on for the amplifier's ATO Logic to function. This is achieved by having the "VACATION switch" in the ON position (refer to "Rear-Panel Controls and Connections": VACATION switch section).
2 The front-panel momentary-contact switch will power on, and place into standby, the NAD CI-series amplifier, denoted by the green LED labelled SWITCH. If you power on the amplifier via the front panel switch, the amber standby LED will turn off, and the SWITCH LED will turn green. Once you turn on the amplifier via the front-panel switch, only the front-panel switch can return the amplifier to standby state.
3 The 12V-TRIGGER LED illuminates green when the amplifier switches from standby to power on state via the 12V input (refer to "Rear-Panel Controls and Connections": 12V-TRIGGER INPUT section). Once you turn on the amplifier via the 12V-IN TRIGGER, only the absence of the 12V can return the amplifier to standby state.

4 The SENSE LED illuminates green when the amplifier senses a signal greater than 20mV RMS on any of the amplifier inputs refer to "Rear-Panel Controls and Connections": SLEEP/WAKE, SENSE/DEFEAT section). Once you turn on the amplifier via the SLEEP/WAKE sense logic, only the absence of a signal to all the amplifier's inputs can return the amplifier to standby state.
5 The OMC LED illuminates amber when the amplifier senses too much input signal or the load impedance drops below 2 to 3 Ohms, in either case a potential fault condition. When the fault condition is removed, the OMC LED will turn off, and the amplifier will return to normal operation.
6 The PROTECTION LED illuminates red when the amplifier protects itself. For example, in the unlikely event of overheating, protection would be active and the protection LED would light red. The amplifier will stay in this state until one removes the fault condition. Once you remove the fault condition, the amplifier will come out of the protection state, and the amplifier will return to normal operation.

RACK-MOUNT INSTALLATION

Instructions for installation of the NAD CI-series amplifier are supplied with the Rack-Mounting hardware. Supplied with these instructions are 8 pieces of plastic bushings and 4 #10-32 bolts. These bolts with specifically designed plastic bushings are engineered to prevent ground loops and will support the weight of the NAD CI-series amplifier (see Figure 1).

Figure 1

Since the NAD Cl-series amplifier is a heavy amplifier, we recommend that you mount the NAD Cl amplifier as close to the bottom of a rack as possible to promote a stable Rack-Mount installation.

The NAD CI-series amplifier takes up 3 standard, rack places on an EIA/IEC 19-inch rack. The NAD CI-series amplifier needs special consideration when rack-mounting to allow sufficient ventilation space all around the amplifier. Thus we recommend one should allow at least a one-rack-space below and above the amplifier as clearance, and that you allow more than 2 to 3 inches (5 to 7.5cm ) of space on all six sides of the NAD CI-series amplifier. Please refer to the "Ventilation Air Flow" specification found at the back of the instruction manual for maximum airflow requirements.

SHELF-MOUNT INSTALLATION

REMOVAL OF RACK-MOUNT BRACKETS

This unit may be installed on any level surface that is strong enough to support the amplifier's weight. Please refer to the "Specifications" section at the back of the instruction manual for the exact weight of your NAD CI-series amplifier. Since the NAD CI-series amplifier was shipped with Rack-Mounting hardware attached, below is the removal procedure of the rack-mounting shelf brackets. We strongly recommend that you follow these procedures in order to prevent damage to the NAD CI amplifier or personal injury:

To detach the rack-mount bracket, place the amplifier on a flat surface, remove each set of three fixing screws on each side. Once the screws are removed, slide the bracket toward the rear of the amplifier to release it from its fittings in the chassis bottom surface and then slide the bracket toward you.

For self-mount installations of the NAD CI-series amplifier, we recommend that you do not place equipment on top of the amplifier. Leave at least 2 to 3 inches (5 to 7.5cm ) on all sides of the amplifier so that the NAD CI-series amplifier achieves adequate airflow. We strongly recommend that you do not block the side, top, back and front, airflow vents. Since its power transformer generates a significant magnetic hum field, a turntable (especially one with a magnetic pick-up cartridge) or a television should not be located adjacent to, directly above, or below the amplifier.

SPEAKER HOOK-UP

This amplifier is equipped with special high-current, binding-post speaker terminals to handle the highest peak-power levels that may occur with low-impedance speakers. At moments when the amplifier is producing maximum power, voltages of nearly 100V may be present on the speaker terminals, so plastic covers protect the terminals. To connect loudspeaker cables, first switch off the amplifier's power by disconnecting the AC-power cord from the wall outlet.

Connect the wires from one of your speakers to the "+" and "-" terminals on the rear panel of the NAD Cl-series amplifier. In each channel, the red terminal is the positive "+" output, and the black terminal is the negative "-" or "ground" terminal (see Figure 2).

Use heavy-duty (16-gauge/2mm or thicker) wire, especially with 4-ohm loudspeakers. Bare wires can be connected directly to the binding-post terminals. For a longer lasting and more corrosion resistant connection, you may install speaker cables with gold-plated connectors (pin connectors or spade lugs), or you can install such connectors on the wires yourself. Connections to each binding post may be made in the three ways described below.

1 Pin connectors: A pin connector is a slim metal shaft that is crimped or soldered onto the end of a wire. The threaded shaft of each binding post contains an opening that accepts pin connectors up to 3mm in diameter. Unscrew the plastic bushing on each terminal to expose the hole in the metal shaft. Insert the pin connector through the hole, and turn the bushing clockwise until it is tight (see Figure 2).
2 Spade lugs: Unscrew the plastic bushing, insert the U-shaped spade lug into the oblong gap and tighten the bushing down on it (see Figure 2).
3 Bare wires: Separate the two conductors of the cord (if they are supplied as a pair), and strip off a half-inch (1cm) of insulation from each. In each conductor, twist together the exposed wire strands. Unscrew the plastic bushings for "+" and "-" insert the bare wire through the hole in the metal shaft, and tighten the plastic bushing until it grasps the wire securely (see Figure 2). Check to be sure that no loose strand of wire is touching the chassis or an adjacent terminal. Re-tighten the bushing after a week or so to make sure that any play that may have developed is eliminated.

Figure 2

PHASING

Stereo speakers must operate "in phase" with each other to produce a focused stereo blend and to reinforce rather than cancel each other's output at low frequencies. An in-phase connection is assured if the red (positive) terminal on the amplifier is connected to the red (positive) terminal on the loudspeaker in each channel. If your speakers are easily moved, their phasing can easily be checked. Make the connections to both speakers, place the speakers face-to-face only a few inches apart, play some music, and listen. Then swap the connection of the two wires at the back of ONE of the speakers, and listen again. The connection that produces the fullest, most extended bass output is the correct one. Once you have determined the correct phasing, connect the wires securely to the speaker terminals, being careful not to leave any loose strands of wire that might touch the wrong terminal and create a partial short-circuit, then move the speakers to their intended locations.

If the speakers cannot easily be placed face-to-face, then phasing must rely on the "polarity" of the connecting wires. The speaker terminals on the amplifier are identified as red "+" and black "-" in each channel. The terminals at the rear of the speakers are also marked for polarity, either via red and black connectors or by labels: "+" , 1 , or "8 ohms" for positive , - , "0", or "G" for negative. The red "+" terminal on the amplifier should be connected to the red (positive) terminal of the speaker in each channel. To facilitate this, the two conductors comprising the speaker wire in each channel are different, either in the colour of the wire itself (copper vs. silver) or in the presence of a small ridge or rib-pattern on the insulation of one conductor. Use this pattern to establish consistent wiring to both speakers of a stereo pair. Thus if you connect the copper-coloured wire (or ribbed insulation) to the "+" amplifier terminal in the Left channel, do the same in the Right channel. At the other end of the wire, if you connect the coppercoloured wire (or the ribbed insulation) to the red (positive) terminal on the left channel speaker, do the same at the right channel speaker.

NOTE

Safety organizations recommend that the speaker terminals of a very powerful amplifier should be covered. Potentially dangerous voltages are present on these terminals when the amplifier is producing maximum power. For your protection and in order to comply with these regulations, we have chosen speaker terminals of the very highest quality for the NAD Cl-series amplifier. These terminals are covered by plastic bushings, which prevent the touching of metal parts.
