Installation & User Guide About this manual This manual is a comprehensive guide to the installation and operation of the TAIDEN Digital Audio Power Amplifier (PA). It includes the detailed description of the functions and interfaces of the PA, including connection, installation, and operation. The manual is divided into the following chapters: Chapter 1：Overview An introduction to the Digital Audio Power Amplifier.
Chapter 1 Overview Digital audio power amplifier (hereinafter referred to as "PA") adopts the high efficiency class D power amplifier and switching mode power supply technology, the efficiency under conventional conditions is more than 80%.
Chapter 2 Functions and indications Front panel of HPA-2016/02 Front panel of HPA-2016/04 Rear panel of HPA-2016/02 Rear panel of HPA-2016/04 Figure 2.1 Digital audio power amplifier indicator will turn to green. 1. Power switch Power on/off. 6. Power indicator The "Power" indicator turns to green when power 2. Gain control Gain is controlled by dB attenuation. With the on. minimum set, the signal is completely cut off. 7. Signal input Male XLRM socket. 3.
10. Mode Switch Gain switch: When the gain of PA is 1 Vrms, the input sensitivity is 1 Vrms; When the gain of PA is 0.7 Vrms, the input sensitivity is 0.7 Vrms; Mode switch: MONO (DIP switch: MONO): signal inputs from channel A and output from channel A&B; MONO: signal inputs from channel C and output from channel C&D; STEREO (DIP switch: STEREO): channel A&B&C&D works independently; BRIDGE (DIP switch: MONO): signal inputs from channel A/C and output from channel A/C; 11.
Chapter 3 Connection and operation 3.
3.3 MONO mode 3.4 Bridge mode Note: In the bridge mode, the DIP switch is set to MONO, the signal is input from the A/C channel, and output from the A/C, and the output terminal is connected to 1+ 2-; The constant voltage output setting is the same as the bridge output setting.
3.5 Operating instructions Please confirm before installation: which will form ground loop and cause oscillation; The power cord not connected to the power 4. Do not connect the output to the power supply, socket; battery or mains supply. Otherwise it may cause The power switch is off; an electric shock; Volume knob turned off (counterclockwise to 5. limit).
3.6 Troubleshooting The following table lists the main reasons for the abnormal work and treatment measures, as well as the circuit protection in each case.
