Classic audiophile preamp from Bel Canto Design. This unit was recently inspected and serviced by Matt Cramer of Ace Tomato Audio, the Bel Canto Design factory-authorized service center, who gave it a full bill of health: I started by running some frequency tests and all looks good. Basically the unit measure perfectly flat. ... You’ve got a late Rev B unit thats a perfect candidate for upgrades. Im happy to share the upgrade options Matt suggested. There is a small blemish at the rear of the top of the unit, so I cant call it mint, but it is in excellent condition. A manual and power cable are included, as is an aftermarket preprogrammed remote. (Other remote options ranging from original to aftermarket, and from $800 to $300, are available from Ace Tomato.) Im also throwing in two WBC XLR cables (Canare Cable, Neutrik connector) to take advantage of the units balanced connections. The Pre1 comes double boxed in factory packaging. Specifications Volume setting for unity gain • 84 Input overload • 5 Volts rms Bandwidth Into >600 Ohms • 0 Hz-200 kHz Signal to Noise Ratio re 1 volt out • >100 dB A weighted, 20-20KHz Distortion at 1 Volts rms Out • <0.01% Input configuration and impedance • Single-ended/balanced 20K ohm Output Options • 2-XLR Balanced; 2-RCA; 1-buffered RCA Tape Out Output Impedance • 50 ohms Maximum Output Level • 10 volts rms Balanced Gain Single-ended • 16 dB Gain Balanced • 16 dB Power Requirements • 100-120 VAC 50-60 Hz or 230-240 VAC 50-60 Hz 25VA Size • 17.5”W x 15”D x 4”H (mm x mm x mm) Weight • 14lbs. (6.5kg) The Pre1 output stage uses the latest integrated technology to combine multiple amplifiers and Laser trimmed precision resistors in a true balanced output stage. This balanced stage mimics the operation of a transformer, providing ideal line-level audio drive into either a balanced or single-ended load. This operation eliminates ground loop issues with power amplifiers when used with either the RCA outputs or the XLR. This assures maximum signal to noise and extremely low distortion with the shortest audio signal path. The power supply uses a separate low noise regulation for each channel’s gain stage. Audio grade decoupling capacitors, star grounding and careful signal routing insure that low-level signals are preserved. The volume control is a precision Crystal 3310 potentiometer controlled by a microcontroller. This device provides extremely low noise and distortion coupled with high accuracy. We have found the sonic quality to be as good as or better than the best potentiometers and switched attenuators with a long useful life and no wear The input processing provides two (2) true balanced input connections and three (3) RCA jack connections plus Tape In. The Tape Output is an RCA output with an active audio-grade buffer preamplifier to isolate the internal signal bus from the tape output. The main outputs are a single-ended RCA and a balanced connection for use with balanced cables and power amplifier inputs. The elegant simplicity of the signal path and gain stage allows the Pre1 to preserve the audio signal quality.
