Speaker impedance taps of 4, 8 and 16 have been provided for direct connection of speakers to the amplifier when the distance

between the amplifier and speakers is less than 50 meters. Use 23/36 or thicker cable for connections. Be sure that total

impedance of speakers is equal to or above the impedance specified on the terminal strip.

The Bass and Treble controls should be individually set to the

desired level as explained below.

BASS: This controls the tonal quality of low frequencies

produced by musical instruments like Tabla / Drum etc., and to

some extent male human voice. When this control is

advanced towards BOOST position, it will boost i.e. increase

the intensity of the low frequencies. Similarly, when it is

lowered towards CUT position, it will cut i.e. reduce the

lowered, towards CUT position, it will cut i.e. reduce the

intensity of high frequencies.

Put the FM / MIC-2 Switch in FM position.

Tune to the desired FM station by rotating the Tuning Knob.

FM Antenna Screw Strip has been provided for optimizing the

reception of the tuner by connecting an external antenna.

In case of strong local stations, or when the equipment is situated

near a transmitting station, the external antenna may not be

required. In case of fringe areas where the signal is very weak, a

To get long trouble free service, maintenance is essential.

After some use the Head, Capstan, Pinch Roller etc. that

come in contact with the tape, become dirty due to dust or

magnetic material on the tape. Dirty heads cause loss of high

frequencies and the output falls. Dirty capstan and pinch roller

will cause unstable tape speed, leading to increased Wow

and Flutter.
