In t roduc t ion Important Design Features of the Citation 22 and Citation 24 Power Amplifiers. Thank you for choosing Citation. Judging from your choice of power amplifiers, you are a discriminating music listener. You now own a superb piece of high fidelity equipment. Used properly, you are about to begin thousands of hours of musical enjoyment. While you are probably no beginner when it comes to high fidelity components, we nevertheless ask you to read and carefully follow the instructions in this manual, to insure a successful partnership between you and your new Citation Power Amplifier. Actual hook-up instructions begin on page 7. 01400.00 ,Rt t It has long been proven both theoretically and in the real world that loudspeakers regularly draw extremely high currents in reaction to dynamic voltage fluctuations in music. Producing a design with simultaneous high current, high voltage and high- speed performance requires rugged, large-capacity electrical and electronic components. Your Citation Series Power Amplifier uses special industrial-grade, triple-diffusion, bi-polar power and driver transistors which are fully capable of both speed and ruggedness. pi*ObP.#01440 wi Lo 'POO Many amplifier designs compromise overall sound quality in the quest for lower and lower Total Harmonic Distortion specifications by incorporating excessive negative feedback. We have taken the far more difficult route of designing the Citation 22 and 24 from the very beginning for inherently lower gain, low Total Harmonic Distortion and very wide open-loop bandwidth. Careful use of minimal negative feedback produces still wider bandwidth and even lower THD. Incoming music signals are perfectly correlated to any necessary low level negative feedback, resulting in extremely fast amplifier reaction time. Neal Witti Instead of settling for less expensive asymmetrical circuitry, (with excessive amounts of feedback correction to avoid even order harmonic distortion), the Citation 22 and 24 employ fully symmetrical circuitry in each individual stage from the input jacks to the speaker terminals. Complex musical waveforms are reproduced flawlessly, and the resulting sound is relaxed and natural. ru pretriallayOut and Cptistaittipd, We have treated your Citation amplifier design as two individual mono amplifiers with only a power cord and a chassis in common. Each channel is fully independent from preamplifier input to speaker terminals to minimize crosstalk and differing power demands. Low level preamplifier inputs are mounted as far as is physically possible from the dual power transformers. Since flux generation from their windings is inescapable, we have oriented the input circuitry vertically, in parallel to the flux pattern of the transformers for minimum interaction. The result is almost complete freedom from internal noise interference. In addition, power storage capacitors are placed in the closest possible proximity to power transistors, so energy can be instantaneously transferred to the output devices.
