Pioneer SX-1500TD

 A Powerful Receiver of Tremendous power and Fidelity, Beautifully Packaged in the Most Up-to Date Design.

The SX-1500TD features highly advanced circuitry. An FET frong and ensures extremely sensitive FM reception. There are four IC's in the IF section for excellent selectivity, and a monolithic IC in the multiplex section for improved separation. Silicon transistors ensure low-noise music power of a tremendous 180 watts. In addition, a fine dynamic microphone comes with the SX-1500TD for microphone mixing. You can connect up to three different stereo loudspeaker systems. Uniquely attractive, with its silver and black contrast and polished rosewood end-pieces.

 Center Channel Output

The SX-1500TD has a center channel output on the rear panel, providing the composite signal (L+R) for a 3-D (three-dimensional) system, when you connect another amplifier to the center channel output.  In addition, stereo music can be recorded into a monophonic tape recorder with this output which is controlled by the preamplifier section of the SX-1500TD.

 Phono Inputs

The SX-1500TD has two sets of phono inputs, enabling you to compare cartridges. Phono 1 is for magnetic and ceramic cartridges, and Phono 2 is for magnetic cartridges.

AC Outlets

There are three AC outlets for turntables and tape decks used with the receiver, a switched AC outlet for 230 VA and two unswitched AC outlets for 230 VA.
