Connect it to the ground terminals (7/7) of the Akai amplifier.
Illustrations indicate additional connections only.
If your DAT deck has an optical or coaxial type digital interface connection system, you can connect the Akai amplifier to the DAT OPTICAL terminal or the COAXIAL jack directly.
If you have a 2nd cassette deck
Use the DAT REC/PLAY jacks for connections. Connect the DAT REC jacks of the Akai amplifier to the LINE IN jacks of your cassette deck. Connect the DAT PLAY jacks of the Akai amplifier
to the LINE OUT jacks of your cassette deck.

To increase the super bass note
.... Use the SUPER BASS control.
To increase or decrease the bass note .... Use the BASS control.
To increase or decrease the treble note .... Use the TREBLE control.
Depress the LOUDNESS button to ON ( - ). When listening to music at normal or high volume levels, set the LOUDNESS switch to OFF ( - ).
The human ear is less sensitive to low and high frequencies at low volume levels. If these frequencies are not boosted or compensated, the sound will seem unnatural. A more natural sound can be obtained by boosting the bass and treble responses. This is called loudness compensation.
It is best to use a monaural source to test the balance. After setting the volume, tune in an AM station and move the BALANCE control to the left or right to boost the volume in the left or right channel respectively.
Set the SUBSONIC switch to ON (-). For other source playback except record playback: Set the SUBSONIC switch to OFF (-).
The subsonic filter will eliminate the ultra low frequency noise (below 15 Hz to 20 Hz) during record playback. Whatever this amplifier interprets as a playback signal will be reproduced. Sometimes this will include unwanted noise such as subsonic noise during record playback. The subsonic filter will eliminate this.
Headphone use and SPEAKERS switches
The SPEAKERS A and B switches allow you to switch between the speakers connected to the A SPEAKERS terminals or the B SPEAKERS terminals on the rear panel of the Akai amplifier.
If only one set of speakers is connected to the rear SPEAKERS terminals, simply set the other switch to OFF. When listening through headphones, set both speaker switches to OFF.
When the Akai amplifier is turned on, no signal will be output to the speakers for a few seconds. The power indicator will first light up red for a few seconds, then change to green when the Akai amplifier has gone into normal operation mode.
This is due to the protection circuit which prevents output of noise when the Akai amplifier is turned on.
The protection circuit also functions during playback to protect the speakers from overloading, and to protect the circuit from damages. When speakers with less than rated impedance are used, the protection circuit will short-circuit the + and -, speaker cords.
When the protection circuit is engaged, the POWER indicator will change from green to red and output signals will be cut automatically.
Should the sound be cut during playback and the power indicator changes from green to red:
The playback characteristics of the speaker system(s) are greatly influenced by the placement and the room in which the speakers are used. For example, if the speaker system is placed near a hard wall, the bass will sound better but the treble might seem too strong. Play back some music without using the tone controls and move the speaker system around to find the best location. However, please keep the following in mind.
If during playback, you cannot hear the bass fully or the sound does not seem to be in stereo
Check the speaker connections. Make sure that + wires are connected to + terminals and - wires to - terminals
Remote control operation will not take place
The BALANCE control and the tone control are not effective
Check the DIRECT OPERATION switch. Set the switch to OFF.
Check the speaker system's impedance. Use a speaker system of more than 6 or 12 ohms impedance.
Should a problem persist, write down the model and serial numbers and all pertinent data regarding warranty coverage as well as a clear description of the existing trouble. Then contact your nearest authorized Akai Service Station.
