USER’S GUIDE

1.1 Overview

Welcome to use this self-made 4*100W audio amplifier board which is a perfect class-D

architecture integrated with Tripath’s high performance TC2000 and TP2050 chips

supporting dual channel audio amplification. Powered by any DC voltage from 10V to 30V,

this high efficiency amplifier board is capable of outputting up to 100W per channel. It can

be used to drive 4Ωor 8Ωpassive speakers. With high efficiency, it especially is available

for the outdoor venues where power supply is always in consideration.

TC2000 is a dual channel audio controller produced by Tripath using its patent Digital

Power Processing technology (DPPTM). Combined with switching power output stages

TP2050, it can achieve class-T audio power amplification, as well as lower THD+N and

higher S/N ratio.

For 100W power output, this amplifier board integrates one TC2000 chips and two TP2050

chips so that it supports dual-channel audio amplification of up to 100W each. Resistance

and capacity components of high quality are used to gain the perfect timber, finally realize

high S/N ratio, low THD+N, wide frequency response range etc.

Note:

1. Never connect more than one group of speaker to the audio output

2. Never connect CH1_OUT- 、CH2_OUT- together since they belong to different

NETs.

3. Refer to on-board descriptions for connection details.

2.4 DC Offset

If it is not quite necessary, DO NOT trim the output offset by adjusting “R51”, “R56”,

“R61” and “R65” on the board since the output offset has been regulated to a range of

±10mV.

Note: Never adjust these potentiometers unless necessary, improper adjustment may

damage your speakers.

2.5 LED Indicators

This amplifier has 1 power LED indicator which is marked as “Power Indicator (D1)”.

“Power Indicator (D1)” will be illuminated in green when power-up.
