11 INSTALLATION AND MOUNTING 1. AMPLIFIER LOCATION The REFERENCE Class A PICASSO amplifier employs highly efficient circuitry and a unique Chassisink TM design to maintain lower operating temperatures. Additional cooling may be required if the amplifier is located in a tightly confined area or when ...

Page 12 - INSTALLATION STEP 5; LEVEL SETTING

12 INSTALLATION 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 are set between 500 mV and 5.0 V. LEVEL SETTING The input levels are...
