Page 4: Design Features
DESIGN FEATURES Audiophile Circuit Topology - The REFERENCE Class A PICASSO is designed with the shortest signal path possible, resulting in the most sonically transparent amplifier Soundstream has ever built! 2 ohm Satellite Drive Ability - The REFERENCE Class A PICASSO amplifier is designed to drive satellite speaker loads down to 2 ohm stereo (4 ohm mono). - Page 5 range from 13.2 to 14.4 volts. Fault Monitor LED on the top panel notifies you of blown power supply fuses. Dual Discrete Class A Drive Stages - Over six times the drive current of most amps, which maintains performance into low impedance loads. Drive Delay Muted Turn-on/off Circuit - A unique circuit which completely eliminates any amplifier-related turn-on/off noises.

Page 8: Selecting Input Modes
INSTALLATION STEP 1 COHERENT STEREO™ / MIXED-MONO / BRIDGED MONO The REFERENCE Class A PICASSO amplifier has the ability to operate in any one of the following modes: Coherent Stereo™ with identical left and right stereo channels for maximum fidelity. Best choice for satellite speakers. -
Page 9: Balanced / Unbalanced Input
INSTALLATION STEP 2 BALANCED / UNBALANCED INPUT The REFERENCE Class A PICASSO amplifier has the ability to accept either standard Unbalanced RCA signal inputs, or Balanced "Pro Audio" inputs with the use of the Soundstream BLT Balanced Line Transmitter or some other balanced line audio source. Before installing your system, you should decide upon which signal type you wish to run. -

INSTALLATION STEP 4 INSTALLATION AND MOUNTING 1. AMPLIFIER LOCATION The REFERENCE Class A PICASSO amplifier employs highly efficient circuitry and a unique Chassisink to maintain lower operating temperatures. Additional cooling may be required if the amplifier is located in a tightly confined area or when driving especially low impedance loads at extremely high levels. -
Page 12: Level Setting
INSTALLATION STEP 5 The input levels are adjusted by means of the individual channel input level controls located on the front of the amplifier. This is a unique dual-stage circuit that adjusts both level and gain. This topology maintains better Signal to Noise ratios even when using sources with minimal output. -
