Bel Canto grew from the quest to achieve the ultimate musical satisfaction from an audio system. This quest began with the discovery of the inherent sonic qualities and musical performance potential of a nearly forgotten technology, the single-ended triode amplifier.
Design Features 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.
Unpacking This box should contain the following parts: a piece is missing, please contact your dealer or Bel Canto Design. Save all packing materials as the packing is specially designed to protect the preamplifier for shipping or transporting it. If you lose or damage the packing materials and carton, please contact your dealer or distributor before attempting to transport the preamplifier. 1 - Pre1 User's Guide 1 - Power Cable for connection to utility power [1.
Front Panel Controls 1) Volume Up – increases the output gain in 0.5 dB increments from 0 to 100 with 100 being maximum gain. 2) Volume Down – decreases the output gain in 0.5 dB decrements. 3) Balance Left – decreases the gain of the right channel in 0.5db increments to a maximum of -6 dB. 4) Balance Right – increases the gain of the right channel in 0.5db increments to a maximum of +6 dB. 5) Mute – Red Led above the mute button will illuminate when the preamplifier is in mute mode.
Rear Panel Connections The rear panel provides 5 total source inputs and 3 total source outputs, including RCA and XLR type connections. Beginning from the left side of the rear panel the connections are as follows: • XLR Output Jacks for Left and Right Channels These outputs go to your power amplifier or active crossover if it has XLR inputs.
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.
