1 INTRODUCTION PRODUCT CONCEPT AND DESCRIPTION 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. There are two levels of modules available for the Audio Suite: "Basic" modules (beginning with the letter B) and "Premium" modules (beginning with the letter P). They provide two levels of performance and price. Premium and basic input modules may be used together in the same mainframe. However, Premium and Basic output modules may not. Module types include the phono inputs (100 series): P101, P100, B100; the line inputs (200 series): P201 (CD, DAT, Digital Processor), P200 (Tape, CD, Tuner, Auxiliary, Video, DAT) and B200; the outputs (300 series): P301 and B301; and the Professional modules (600 series). This modular flexibility enables the user to acquire an Audio Suite with any comple- ment of modules initially and add to or upgrade as desired.

2 INSTRUCTIONS UNPACKING Prior to opening, inspect the outside of the cartons for signs of shipping or handling damage. Report any evidence of abuse immediately. Open the cartons carefully and remove the contents from the packing. Take care not to scratch the surfaces of the unit. Save all packing material and boxes for reuse in the event the unit must be shipped in the future. Should the boxes become lost, replacement boxes are available from the factory. Packing contents: Mainframe with selected modules and blank bays 9M DC cable Accessories to be ordered and shipped separately: Cello Strings Master Supply - with AC cable and ground jumper 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 connec- tors. 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 com- ponents 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. ADAPTOR LIST (See appendix 1)
