What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

If you need a high-quality amplifier for monophonic or  center-channel operation, then the Model 14 is the ideal choice. Available in utility form, it has the same performance specifications and circuitry of each channel of the Model 15.

Power Output Each Channel:  
70 Watts at 4 ohms
60 watts at 8 ohms
40 watts at 16 ohms
Frequency Response:  Within 1 dB,  10 to 60,000 Hz
Damping Factor:  Greater than 30 with 8 Ω load.
Total Harmonic Distortion:  less than 0,1% at and below rated power, 20 to 20,000 Hz
Typical Harmonic Distortion:  0,03% with 8Ω or higher load - at full rated output,any frequency from 20 to 20,000 Hz. Distortion decreases as output level is lowered.
Total Noise:  better than 90 dB below 60 watts into 8 ohms.
Power Requirenets:  105 - 130 V AC, for 50-60 Hz. Easily covertible form 110 volt to 220 volt operations.
