Introduction1.1 The stereo amplifier apparatus specialization in the performance, have versatility-changedoutput (stereo, parallel and bridged selector), you will hear excellence music.1.2. Input matching allows collection with any preamplifier1.3. Excellent frequency echo and sound quality1.4. XLR unbalanced and 6.3 jack output.1.5. High-speed and low noise fan for releasing heat. When the temperature rises, the fanautomatically switches to high- speed, it re-back to normal speed at other times to reducepower consumption1.6. The apparatus have changed limited overload function, when it turns on the apparatusmost output.1.7. Status indicators of SIG and CLIP. When there is any signal added, the SIG LED lights up.When there is overload, the CLIP LED lights up. If anything abnormal happens to thecircuits, the CLIP LED will be continuously on, with no action from the circuits. This helpsthe user to determine which status it is in. .1.8. Power supply of steady circuit adopted to unaided voltage output of highly cabinet.1.9. Output jack specialization in female speaker jack.2.
