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 0.2 - 2 Volts RMS, or from 0.5 - 5 Volts RMS - channels 1[...]

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. Best choice for satellite speakers. Use this mode unless Mixed - Mono is necessary. Mi[...]

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. Before installing your system, you shou[...]

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. INS TA LL ATION STEP 3 up to 10[...]

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. Additional cooling may be required if the amplifier is located in a tightly c onfined area or when driving especially low impedance loads at extre[...]

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 5.0 V. LEVEL SETTING The input levels are adjusted by means of the individual channel i[...]
