Frequently Asked Questions - CXNA71 AIWA

How to clean the cassette deck heads?

Every ten hours of use, clean the heads and tape paths with a cleaning cassette or a cotton swab dipped in denatured alcohol. Wipe the record/play head, erase head, capstans and pinch rollers. Allow to dry completely before inserting a cassette.

Can I record a CD directly to cassette?

Yes. Insert a blank cassette into deck 2, select the CD source, then press the REC/REC MUTE button. CD playback and recording start simultaneously. Use the AI edit function to optimize the track order according to the cassette length.

How to use the karaoke function?

Plug a microphone (3.5 mm mini-jack) into the MIC 1 or 2 jack. Press the MIC button to adjust the mic volume, then ECHO for echo effect. You can also activate VOCAL FADER (attenuates voice) or MULTIPLEX (separates channels) via the KARAOKE button.

What to do if the unit does not power on?

Check that the power cord is properly plugged in and the outlet works. If the unit remains inactive, thermal protection may be activated; unplug it for a few minutes then plug it back in. If the problem persists, contact a qualified technician.

How to program a timer recording?

First set the clock (CLOCK button). Press TIMER twice to display REC, then SET. Set the start time, source (TUNER or VIDEO/AUX), duration, then insert a blank cassette into deck 2. Turn off the unit; the timer will start at the programmed time.

What is the power of the speakers?

The amplifier output power is 100 W + 100 W (6 ohms). The supplied speakers (models SX-NA74, SX-ANA72, SX-FNA71) have an impedance of 6 ohms and a sensitivity of 87 dB/W/m.

Can I connect headphones?

Yes, plug headphones with a 6.3 mm stereo plug into the PHONES jack on the front of the unit. When headphones are connected, speaker sound is automatically muted.

How to adjust the graphic equalizer?

Press the GEQ button repeatedly to select the ROCK (boosted treble and bass), POP (vocals and mids) or CLASSIC (powerful bass and fine treble) curves. To disable, keep pressing until GEO OFF appears.

Why is the sound distorted?

Distortion may be caused by too high volume level (reduce it), excessive T-BASS system (disable it if the source already has bass) or a microphone too close to a speaker (move it away). Also clean the cassette heads if audio playback is affected.

Where to find spare parts or get the unit repaired?

Contact an authorized Aiwa distributor or a qualified technician. Do not attempt to repair the unit yourself. For consumables (batteries, cleaning cassettes), consult audio accessory retailers.

Principle of Aiwua's Front 180^ Speaken System (NSX-A72 only)

Aiwa's Front 180^ Speaker System provides excellent sound balance for true stereo reproduction from any listening angle.

In stereo sound reproductions systems up to now, the listening area where the optimal stereo effect is obtained has been extremely narrow. This is due to the following reasons.

As shown in Figure 2, a conventional stereo system has speakers on the front panel of the speaker system, pointing forward. It is designed for listening in a location directly in front of the front speaker panel.

In this case, as shown in Figure 2, a listener at point ⑧ , located on the center line between the right and left speakers, hears the voice of a singer coming from the center front. Instrumental sounds are distributed evenly between both speakers for an optimal stereo effect.

At point ⑥ , however, located off the center line between the speakers, the distance from the left speaker to the listener is greater than the distance from the right speaker. Sound from the left speaker appears to be faint, and sound from the right speaker appears to be loud. Sound is perceived as coming from the speaker with the greater volume, so that the singer's voice appears to shift toward the right speaker. The normally balanced instrumental sounds also appear to come primarily from the right speaker.

Moreover, since the directivity of speakers increases with higher frequencies, high-frequency sounds from the left speaker become even harder to hear, increasing the impression of imbalance. For these reasons, the listening area which provides even sound balance and the optimal stereo effect is limited to the narrow area shown in Figure 2-8.

To solve this problem, Aiwa has developed unidirectional speakers for this new speaker system featuring cardioid directivity for frequencies of 1 kHz or less. These speakers are pointed inward at angles of 45^ (see Figure 1). Driven by left and right stereo sound signals, these speakers act to increase the width of the optimum listening area (see Figure 3). Because of their cardioid directivity and the 45^ angle of their main speaker axis, they provide enhanced sound reproduction at point in Figure 3. The left speaker is pointed toward the listener, and the right speaker is pointed away from the listener, so that the directivity of the speakers compensates for the differences in perceived volume caused by the differences in distance to the listener. Therefore, the sound of a singer's voice is perceived as coming from a point midway between the speakers, and instrumental sounds are distributed evenly.
