Cello Audio Suite Mainframe preamp control center with external PSU

The Audio Suite is a mainframe which accepts up to ten modular sections thereby
permitting individualized selection of preamplifier features and functions. Its range of
capabilities is almost limitless, making possible a completely flexible approach to
state-of-the-art music system design and development

Four module types included are the MC phono inputs P101, the line inputs P201 (CD, DAT, Digital Processor), B200 (Tape, CD, Tuner, Auxiliary, Video, DAT); and the output P301(Output level and Balance)

CABLE AND ADAPTOR SELECTION
The Premium modules use 3-pin Fischer connectors for the highest quality balanced
line input and output connectors. The Basic modules utilize high quality RCA connectors.
It is recommended that input and output connections be made using Cello Strings cable.
Cello Strings are stocked in lengths of 1, 1.5, 2, 3, 5, 8, and 10 meters. Custom lengths
are available on special order. Terminations are available to suit the particular components of the system.
Balanced lines may be converted to single ended operation. The best way is to use Cello
Strings cable (which has three conductors and a shield) with a Fischer male connector
on one end and an RCA connector on the other. This preserves the three-wire system
from the amplifier to the source unit and provides better grounding and common mode
rejection. If this is not convenient, adaptors are available for single ended operation.
To interface with XLR systems, it is recommended that Cello Strings cable be used
with a Fischer connector on one end and an XLR connector on the other end.
