Product Concept and Description

Our high power, reference level, Performance Amplifier was developed by cello to obtain the most natural sound and widest dynamic range from the finest speaker sys- tems. The Encore 150 offers similar sonic qualities for music listeners who seek the ultimate in a medium-high power reference amplifier. The Encore 150 consists of two mono block amplifier units with dual choke input. It is the recommended mate for all 8 ohm and 4 ohm speaker systems. It has a tight, well extended and accurate bass as well as an open and detailed high end offering a clear, effortless, balanced sound coupled with high speed that are the hallmarks of Cello.

Compatibility

The Encore 150 is virtually compatible with all high quality preamplifiers and loudspeakers from other manufacturers. In fact, Cello engineers designed the Encore 150 specifically to be compatible with a wide variety of available equipment. The input impedance is one megOhms so that it does not load even the most sensitive tube preamp. Output impedance is low enou g h to ensure against interactions with speaker loads. Noise is low enough so that high efficiency speakers can be used without audible residual noise. Input sensitivity is reasonably high permitting the Encore 150 to be easily driven by any hi g h quality preamplifier. For balanced line inputs the industry standard connector is the XLR type. Cello does not use XLR connectors because they do not meet Cello's standard for contact quality and reliability. Instead, Cello uses the 3 pin Fischer connector series for all balanced line applications. Cello Strings cables are available through all authorized dealers with 3 pin Fischer on one end and XLR or RCA on the other end for interfacing with non- Cello equipment. Use of Cello Strings cable is highly recommended because a number of balanced cables on the market do not actually provide the correct complement of conductors and shield in their construction.
