1 REFERENCE Class A PICASSO PICASSO 4/3/2 Channel Power Amplifier OWNERS MANUAL AND INS TALLATION GUIDE.
2 CONGR ATULATIONS! You now own the REFERENCE Class A PICASSO PICASSO Amplifier , the most musical amplifier ever created for the 12 volt environment. Your Soundstream REFERENCE Class A PICASSO amplifier will outperform any other amplifier in the world.
3 TABLE OF CONTENTS Design Features ........................................................................................................ 4 - 5 REFERENCE Class A PICASSO Diagram ..................................................................... 6 - 7 Selecting Input Modes .
4 DESIGN FE ATURES • Audiophile Circuit Topology - The REFERENCE Class A PICASSO is designed with the shortest signal path possible, resulting in the most sonically tr ansparent amplifier Soundstrea.
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 th e drive current of most amps, which maintains performance into low impedance loads.
6 PICASSO PICASSO.
7 Key to Callouts 1. Fault LED - Indicates a blown fuse. 2. Power LED - Indicates amplifier power on. 3. Input Overload Indicators - Indicates the signal input level or input gain level is too high - channels 1 & 2. 4. Input Level Selector Switch - Selectable input sensitivity range from 0.
8 INS TA LL ATION 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 Ste reo™ with identical left and right stereo channels for maximum fidelity.
9 INS TA LL ATION 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 o f the Soundstream BLT Balanced Line Transmitter or some other balanced line audio source.
10 WIRING POWER AND GROUND To ensure maximum output from your REFERENCE Class A PICASSO amplifier, use high quality, low - loss power and ground cables. The PICASSO amplifier will accept up to 4 gauge power and ground cables. Determine from the chart below the minimum gauge power and ground wire for your application.
11 INS TALLATION AND MOUNTING 1. AMPLIFIER LOCATION The REFERENCE Class A PICASSO amplifier employs highly efficient ci rcuitry and a unique Chassisink TM design to maintain lower operating temperatures.
12 INS TA LL ATION STEP 5 NOTE: Even though the S/N ratio with low output sources is better with the PICASSO amplifier than others, your best combination of output level and Signal to Noise ratio will be achieved when the input levels a re set between 500 mV and 5.
