Thank you for purchasing a Bel Canto Design eVo amplifier. As the proud owner of an eVo you can expect high quality performance for years to come. The eVo presented in the following pages is designed to maintain very high value, setting the benchmark for design, quality and sonic accuracy while maintaining our heritage of musicality and realism.
Design Features • High efficiency Digital Power Processing output stage for cool operation • Damping Factor >100 • Analog signals are processed at small signal level, all large signal power is generated using the switching output stage • Regulated, low noise supplies for all analog stages • 700 watts of continuous power output capability in Balanced Mono mode • Optimized balanced and singleended input stage • THD and IMD <0.
Design Features (cont’d) Feedback is taken before the LC filter and fed back to the digital power processor. This feedback is used to insure that any variations in the switching speed of each output device are compensated for, optimizing the linearity of the output stage. Warm-Up The eVo amplifier’s sonic performance will continue to improve over the first several weeks of operation.
Unpacking your new Evo The box containing your eVo amplifier contains the following parts: 1 (one) - eVo audio power amplifier 1 (one) - eVo 2/4/6 User's Guide 1 (one) - Power Cable for connection to utility power [6' 7" - 2 meters long] Carefully unpack each piece and check for shipping damage. If there is any damage, or if a piece is missing, please contact your dealer or Bel Canto Design, Ltd.
Initial Setup Please refer to the front and rear panel diagrams, as needed. [Page 8] Line Level Inputs Warning: Always disconnect power to the amplifier when changing cables. Two inputs per channel are provided. The RCA jack is a standard input that accepts single-ended sources.
Loudspeaker Connection and Power Output Options Warning! Make certain that any output terminal is not connected to a chassis or earth ground. Connect loudspeakers to the outputs of the eVo amplifier using the 5-way binding posts located on the rear of the amplifier. The red or black center plug in the output post can be removed for use with banana type connectors. Unscrew the binding post until the center plug comes out. Do not connect speaker terminals to a chassis or earth ground connection.
Power On and Operation The front panel switch or rear panel 12 volt trigger input is used to power on the amplifier. When using the 12 volt trigger the front panel switch should remain in the off (out) position. The eVo amplifiers have been designed to remain powered up at all times, their very low standby power is conducive to this. The blue front panel LED remains on when the eVo is in normal operating mode.
Amplifier Placement eVo Amplifier Placement Within Your System The most typical arrangement places the eVo on the lower shelf of a rack or shelf unit; some users prefer to have the eVo on its own stand. Because the eVo runs so cool it can be placed in many system locations without compromise. We do not recommend placing weights or other objects directly on the eVo. This may mar or scratch the chassis finish. Dampen a soft cotton cloth with warm water for cleaning the outer surfaces.
