1. 2. 3. 4. 5. 6. 7. 8. Read these instructions Follow all instructions Keep these instructions Heed all warnings Do not use this apparatus near water Clean only with dry cloth. Do not block any ventilation openings. Install in accordance with these instructions. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including other amplifiers) that produce heat. 9. Do not defeat the safety purpose of a polarised or grounding plug.
18. WARNING: The mains plug/appliance coupler is used as a disconnect device, the disconnect device should always remain readily operable and accessible. 19. The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of non-insulated “dangerous voltage" within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock.
0.775 V BRIDGE MONO 0.775 V BRIDGE MONO 45 mm 290 mm 483 mm Cold air is sucked through the ventilation hole in the front panel and the heat is taken out from the rear panel. In order to ensure good heat dissipation, please use the equipment in an environment of 0°C~40°C and ensure that the front and rear panels are unobstructed for clear airflow. If the temperature exceeds 85 degrees, the output voltage will be reduced so avoid excessive rises in temperature.
8Ω 4Ω 8Ω 4Ω 8Ω 4Ω MONO 0.775 V BRIDGE MONO 8Ω 4Ω STEREO 0.775 V BRIDGE MONO Try to use shielded cables. Higher density shielding gives better results. Try to select balanced connections. This will reduce any noise interference. When using unbalanced cables, always use the shortest possible - preferably not more than 3 m. Avoid putting unbalanced cables near AC power lines otherwise undesirable noise could happen. Before changing any connections, please turn off all equipment.
Clipping not only makes sound distortion, but also can damage the tweeter of loudspeakers. You can reduce the input signal to avoid input stage clipping. Strong sub signals can also damage woofers. A transient low frequency signal caused by dropping a microphone is a typical sub acoustic signal. For added protection it is recommended to: a. Install a high pass filter between the mixer and amplifier. b. Turn on the high pass filter in the mixer.
