![]() ![]() ![]() The Premiere Five was noted for its delivery of high-power into complex loads while maintaining a holographic, three-dimensional soundstage. Like the Premier Four, it featured extensive use of conrad-johnson’s proprietary CJD polystyrene capacitors throughout the audio circuit and in the regulated power supplies for the voltage amplification stages. The Premiere Five vacuum-tube power amplifier was similar in design to the Premier Four, but was a mono amplifier using eight E元4 output tubes to produce 200 watts. Input Sensitivity: 0.875 volts Hum & Noise: 96 dB below rated power.Power Output: 100 watts per channel, minimum RMS, at 4, 8, or16 ohms both channels driven from 30Hz to 15kHz with no more than 1% THD or IM Distortion.The Premier Four achieved silky highs, and a remarkable three-dimensional soundstage. It featured extensive use of conrad-johnson’s proprietary CJD polystyrene capacitors throughout the audio circuit and in the regulated power supplies for the voltage amplification stages. The Premiere Four vacuum-tube power amplifier used two pair of E元4 output tubes per channel to produce 100 watts per channel. Gain: Phono Stage 40 dB (phono overload 500 mV at 1kHz).The Premier Three-revision in 1986 involved upgrading the internal wiring to mono-crystal silver, and replacing the balance control with a stepped attenuator. This was an important factor in the Premier Three’s three dimensional soundstage, superior extended high frequency response, and ability to reproduce the “space” between instruments – sonic characteristics that earned the Premier Three the accolade as best sounding preamp of the decade in The Absolute Sound’s Tenth Anniversary issue. This was the first preamplifier to feature the exclusive use of conrad-johnson’s proprietary CJD polystyrene film capacitors throughout the audio circuits and related power supplies. The Premier Three superseded the previous state-of-the-art Premier Two preamplifier. Introduced April, 1983 | Premier Three-revised June, 1986 S/N Ratio: Phono Stage 72 dB below 10 mv input / Line Stage 84 dB below 2.5 volt output.Response: bandpass 2Hz to more than 100kHz.Gain: Phono Stage 40 dB (phono overload 500 mV at 1kHz) Line Stage 27 dB.mode (left, right, stereo, stereo reverse, mono).monitor and recording facilities for two tape decks with dubbing from Tape 1 to Tape 2.Its three-dimensional soundstage set the Premier Two apart from its competition, leading to its top ranking in one noted publication’s survey of top preamps at the time. #Conrad johnson cav 50 manual fullInput Sensitivity: 1.0 volts to full powerĭesigned as a companion for the Premier One, the Premier Two was noted for extended, controlled bass response, and very wide dynamic range.Frequency Response: 20Hz to 20kHz, +0, -.5dB.Power: 200 watts per channel into 4, 8, or 16ohms with no more than 1% THD and IM Distortion, both channels driven from 30 Hz to 15 kHz.Premier Ones are sought after and highly prized by both collectors and audiophiles even today. Complex loads were a breeze and hard to handle electrostatics speakers presented no problem to the Premier One.ĭespite its brute power, the Premier One remained very delicate at the highest frequencies yielding extended high frequency response uncommon in vacuum tube designs and with a remarkably three dimensional soundstage. Ultralinear operation of the 6550 output stage offered an excellent combination of high power and low distortion. Uncommonly powerful for a tube amplifier at 200 watts per channel, the Premier One was identified by one leading audiophile publication as the best sounding power amplifier ever made to that time.Īn enormous power supply with massive computer-grade electrolytic capacitance totaling 4000 micro-farads at more than 500 volts delivered startling deep and controlled bass response not achieved by any other vacuum tube power amp. The Premier One was the first of a line of state-of-the-art contenders to carry the conrad-johnson Premier badge. Introduced: December, 1981 | Premier One-b: September, 1986 ![]()
