The Champion Audio Amplifier Kit with Pre-Amplifier
Refer: Silicon Chip Magazine January 2013
It uses the AN7511 audio IC to deliver 2W music power into 8 ohms from a 9 to 12V supply. Features low distortion, two inputs (mixed 1:1), over-temperature protection (auto-limiting), Mute and standby control. Pre-amplifier is also suitable for microphones and electric guitars, and can be separated from the amplifier for individual use. Kit supplied with silk-screened PCB, heatsink and PCB mount components.

Features:
• Operating voltage range: 4 - 13.5VDC
• Music power: 3W @ 9 - 12V
• Frequency Response: -2.5dB @ 20Hz, -0.2dB @ 20kHz
• Gain: 34dB for Amplifier, up to 58dB with pre-amplifier
• Input Sensitivity for Amplifier only: 52mV RMS @ 5V, 125mV RMS @ 9 - 12V
• Input Sensitivity for Amplifier & Pre-amplifier: 2mV RMS @ 5V, 5mV RMS @ 9 - 12V
• Quiescent current: 2mA (Pre-amplifier) + 30-60mA (Amplifier)
• Standby current: 2mA (Pre-amplifier) + 1-10uA (Amplifier)

Note: Optional 10kohm potentiometer for external volume control use RP-7610
