Use a 3.5mm-to-RCA cable or a dedicated DAC and plug it into the CD or AUX inputs. 3. Powering Up Safely
Power outlets that turn on and off via the amplifier's main power switch. Use these for lower-draw components like tuners. Front Panel Controls and Functions
Over time, the bias current (standardly 20mA per channel) may fall, leading to audible distortion at low volumes. This is typically the only internal adjustment necessary for maintenance.
Approximately 35 to 45 Watts per channel into 8 ohms (stereo). Frequency Response: 20Hz to 20kHz.
