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.
