Precautions

Before starting to use your receiver, please read this manual carefully. Keep the manual at hand for future reference.

• When installing the unit, choose a well ventilated location which does not obstruct heat dissipation and provides firm support.
• Avoid locations subject to direct sunlight or extreme temperatures, moisture, high humidity, or high levels of dust.

Cleaning the Receiver

Caring for the exterior panels of the unit should be limited to wiping with a soft cloth. If necessary, slightly moisten the cloth with a diluted neutral detergent. Avoid using any solvents or alcohol-based cleaners.

Always disconnect the power cord from the AC outlet if the unit is not to be used for a long time. [?]

Never block the ventilation openings on the top of the unit. Proper ventilation is essential to prevent internal heat buildup. Do not cover the unit with drapes or the like, and always leave sufficient clearance above the unit.

Batteries

The remote control uses two R06 (AA) batteries. Ensure correct polarity when inserting. Replace batteries when the remote's range decreases or it fails to operate. Do not mix old and new batteries, or different types. Rechargeable batteries should only be used if clearly marked as such. Remove batteries if the unit will not be used for an extended period. Do not dispose of batteries in fire.

Troubleshooting

Please check the following points before requesting service.

Connections

This section details how to connect various audio and video components to the Nakamichi receiver.

General Connection Guidelines

• Set the power switches of all components to OFF before making connections.
• Take care not to mix up left and right channels.
• Input and output connectors are color-coded: Video signal jacks are yellow; Audio input/output jacks are white for left channel and red for right channel.
• Never insert shorting plugs or similar into unused jacks, as this can interrupt sound or cause damage.
• For video connections, always use dedicated video cables to avoid image distortion due to impedance mismatching.

Speaker Connections

• Connect loudspeakers observing correct left/right channels and polarity (+/-). Reversed polarity can cause loss of bass response and unstable stereo imaging.
• The unit supports speakers with a rated impedance of 4 to 16 ohms. If two pairs of speakers are connected simultaneously, each speaker should have an impedance of 8 ohms or more to prevent damage to the power amplifier.
• Use high-quality, heavy-gauge speaker cable for optimal sound quality. Thin cables with high resistance can impair performance.
• Speaker cables for both channels should be approximately equal in length to ensure proper left/right balance.
• Pay attention to the power handling capability of connected loudspeakers. If it is lower than the receiver's maximum rated output, damage to the speakers may result.
• The receiver's high-current design allows stable operation with a wide range of speaker load impedances. However, avoid driving very low-impedance speakers at high levels for extended periods, especially when using two pairs.

Speaker Impedance Selector Switch (North American Model)

Set this switch according to the impedance of the speakers used:

• 8 ~ 16 Ω: When a pair of speakers with 8 ohms or more impedance is connected to A or B terminals.
• 4 ~ 6 Ω: When a pair of speakers with less than 8 ohms impedance is connected to A or B terminals.
• A + B 8 ~ 12 Ω: When pairs of speakers with 8 to 12 ohms impedance are connected to both A and B terminals.
• A + B 16 Ω ~ : When pairs of speakers with 16 ohms or more impedance are connected to both A and B terminals.

CAUTION: Turn off the Power switch before using the Speaker Impedance Selector switch.

Antenna Connections

• FM Antenna: Use a dedicated FM antenna suitable for your location. For areas with strong signals and multipath interference, a low-gain, high-directivity antenna is recommended. For fringe areas, a high-gain Yagi-type antenna is required. Ensure the antenna is installed as high as possible and away from noise sources like roads and power lines. Use a good, short coaxial cable.
• AM Antenna: Connect the supplied AM loop antenna. Orient it for maximum signal strength. For improved reception or to avoid interference, an additional outdoor AM wire antenna and a ground connection may be necessary. Ensure grounding for lightning protection if using an outdoor antenna.

System Remote Control Connections

By connecting the System Remote outputs on the receiver to the remote control input terminals of compatible Nakamichi cassette decks or CD players, the receiver's remote can operate these components. Use the supplied system remote cables. Specific models may require additional converters (e.g., RC-4, SRC-3, SRC-2) or serial-to-parallel converters.

Use of Pre Out/Main In Terminals

These terminals allow for the insertion of signal-processing equipment like sound processors or graphic equalizers. Remove the jumper plugs connecting Pre Out and Main In jacks before connecting external equipment. Reinsert jumper plugs when not in use. Perform these operations with the unit OFF to prevent speaker damage from noise bursts.

Operation

Memory Tuning

Up to 10 FM/AM stations can be programmed for instant recall.

1. Tune to the desired station.
2. Press the Memory button (Memory indicator lights up for 5 seconds).
3. While the indicator is lit, select the preset station number using the Preset buttons.
4. Press the Memory button again to store the station.
5. To change a stored station, repeat steps 1-4 with the new station.
6. Memory tuning may revert the tuning mode to automatic. If a weak station stored via memory tuning is selected and sound is cut off due to muting, switch to manual tuning.

Last Station Memory

The receiver memorizes the last station received in each band when the band is changed and the station received when the power was turned off. A built-in lithium battery backs up this memory for approximately five years.

Recording

• RE-1/RE-2: Set the Rec Out selector to the desired program source and set the tape deck to record. For three-head decks, setting the Listen Monitor selector to Tape allows real-time monitoring.
• RE-1: The Rec Out selector sends the selected source to both Tape 1 and Tape 2 outputs, allowing simultaneous recording on two tape decks.
• RE-3: Set the Listen Monitor selector to the desired program source and set the tape deck to record. Press the Tape Monitor button for monitoring with a three-head tape deck.

Tape Dubbing

• RE-1: Set the Rec Out selector to "12" or "21" and set the respective tape decks to record and playback.
• RE-2/RE-3: Connect the recording tape deck to Tape inputs/outputs and the playback tape deck output to the Video (Aux) input. Set the Rec Out selector to "Video".

Video Recording (Dubbing)

RE-1: Set the Rec Out selector to the source component. Set the source component to playback and the recording VCR to record. The video signal can be monitored on a connected TV or monitor during dubbing.

FM/AM Broadcast Reception

Automatic Tuning

1. Select automatic tuning (Auto indicator lights up).
2. Choose the AM or FM band.
3. Press the Tuning Up or Down button. The Lock indicator lights up when a station is found. The Stereo indicator lights up for FM stereo broadcasts.
4. If the station is not desired, press the Tuning button again to continue seeking.
5. Interstation noise is suppressed during automatic tuning. If stereo FM broadcasts are noisy, manual tuning may provide clearer sound.

Manual Tuning

For receiving weak stations below the automatic tuning threshold:

1. Select manual tuning (Auto indicator is off).
2. Choose the AM or FM band.
3. Press the Tuning Up or Down button to adjust the frequency. The Lock indicator lights up when a station is received. FM muting is disabled in manual tuning.
