OCTAVE V 80 (Black) Integrated Amplifier w/ MC Phono [Expired]


no longer for sale

One owner; light use Excellent condition; one-owner non smoker home 75-80 WPC; outfitted with KT 88 tubes Black finish, near mint rated 9 per Audiogon scale (it is over a year old) Includes tube cage (I haven't ever used this) Headphone amplifier built-in Can effortlessly drive virtually any speaker; very powerful and incredibly quiet! Original box and packing, remote and all accessories The V 80 features a total of seven single-ended (RCA) inputs - including the Home Theatre Bypass input) and one balanced (XLR) input. One RCA input can fitted with the optional (either MM or MC) Phono Input Board. Outputs included are one RCA Record output, one regulated Preamplifier output, one Headphone output and one Loudspeaker output. The V 80 is equipped with a separate Headphone Amplifier, and the Loudspeaker and Headphone outputs can be switched independently. The pre- and power amplifier sections of the V 80 can be operated independently from each other as well. Black Box/Super Black Box Connector Optional OCTAVE, with the Black Box technology, offers an upgrade path for optimizing the OCTAVE amplifier in respect to the speaker. This flexibility is a unique feature of the OCTAVE brand. The dynamic and tonal stability of an amplifier is strongly dependent upon the stability and capacity of the power supply, therefore the Black Box and Super Black Box were developed as external upgrades to the OCTAVE amplifiers’ power supply storage capacitors by increasing their capacitance by a factor of 4 (Black Box) or 10 (Super Black Box), respectively. This is a tremendous benefit if the speaker is difficult to drive. Loudspeaker efficiency is made less critical, while the amplifier is enabled to handle speakers with extremely low minimum impedances. Ecomode A forward looking feature of OCTAVE is the unique Ecomode power saving electronic circuitry developed to reduce heat and unnecessary power consumption when the amplifier is switched on but not in use. This electronic system controls the power condition and reduces power consumption when the amplifier does not receive a signal for a period exceeding 10 minutes. In this “sleep” mode, the V 80 draws only 20 W idle current. Virtually no heat is produced by the unit, and the heater voltage and the high voltage for the power amplifier section are switched off. When a signal is detected by the V 80, the Ecomode circuit will turn the amplifier back on, with a warm-up/start-up delay of approximately 30 seconds before the unit will operate. Ecomode also serves to increase the lifetime of the tubes, while having an added benefit of improved safety allowing the V 80 owner a level of security against any problems when leaving the unit powered on. BIAS Adjustment The Output stage of the V 80 operates in Class A/B, and therefore requires an adjustable BIAS regulation. The highly sophisticated yet extremely simple yet accurate BIAS calibration system is accessed on the front panel of the unit. It utilizes external precision bias trim pots and LED confirmation, allowing the user to readily monitor the output tubes and simply correct their bias individually at the front panel - without the need of a micrometer let alone any special knowledge or tools. The correct BIAS is vital for the constant sound quality of the V 80. Due to this facility there is no need for a technician to service the V 80 for changing or tubes or to check their condition. The precision of this user friendly system is within 0.5% accuracy. Power Management and Protection System The V 80 is equipped with a multi-stage Soft-Start/Turn-On protection circuit which extends component as well as tube life considerably by protecting against stress caused by typical high inrush currents during switch-on. The unit starts in a defined sequence, with the Protection System monitoring the V 80 completely, and activated whenever a malfunction is detected. Once the Protection is activated, the V 80 is powered down. Optional Phono Stage An internal Phono Stage is available on the V 80 for either MM (47k Ohm) or MC (500 Ohm) cartridges. The phono board includes a 12 dB / Octave sub-sonic filter. The design of the internal Phono Stage is based on passive equalization for the best signal conditioning.
