Introduction 1.1 1.2. 1.3. 1.4. 1.5. 1.6. 1.7. 1.8. 1.9. 2. The stereo amplifier apparatus specialization in the performance, have versatility-changed output (stereo, parallel and bridged selector), you will hear excellence music. Input matching allows collection with any preamplifier Excellent frequency echo and sound quality XLR unbalanced and 6.3ф jack output. High-speed and low noise fan for releasing heat. When the temperature rises, the fan automatically switches to high- speed, it re-back to normal speed at other times to reduce power consumption The apparatus have changed limited overload function, when it turns on the apparatus most output. 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 the circuits, the CLIP LED will be continuously on, with no action from the circuits. This helps the user to determine which status it is in. . Power supply of steady circuit adopted to unaided voltage output of highly cabinet. Output jack specialization in female speaker jack.
