INTRODUCTION
The DDA-120 integrated power amplifier accepts analog, digital and Bluetooth audio inputs from computers, consumer entertainment and streaming devices without the complexity of an audio/video receiver.
In order to have more input options, the DDA-120 accepts a full compliment of sources - one RCA analog, four digital via one USB, one coaxial, two optical inputs, and one expansion slot for a Bluetooth receiver dongle.
Features
• 176.4kHz input sampling rate
• 3GB/s over-sampling rate for smoother, more natural reproduction
- An on-chip clock reference signal for synchronizing incoming digital audio data -Data re-clocking results in ultra low jitter performance
• 100% linear frequency and phase response (+/- 0.1dB from 20 to 20kHz)
- THD+N = 0.07%
• Signal-to-noise ratio > 95dB A-weighted
• High-quality, audio-grade parts throughout

Basic Operating
To Power on/off
ON
ON: Pressing after turning back switch for 15 seconds
5 Sec ...
OFF
OFF: Long pressing for 5 seconds
IMPORTANT!
Speaker Output: Connect the left and right speaker cables to the output terminals. In order to avoid shorting out the DDA-120, before turning on the power, please make sure that the polarity of the speaker cables is properly terminated to the loudspeakers and the DDA-120.
To select the desired input, simply press the Input button it cycles through all 4 inputs sequentially.
