There are several important technical points to match power amplifiers in the speaker system, the most basic considerations are as following:- If the damping factor of the amplifier is ideal (to the speaker) as it directly affects the quality of the low frequency output. If the power amplifier has good heat management, the less heat loss the more power efficiency to the speaker.
Based on the above principles , our engineer has developed the new BK Series professional power amplifier to meet the daily growing fixed installation market. BK series power amplifier power output vary from 300W to 1200W ( 8ohms stereo), 6 models, from Class AB to Class H design.
Features:
1.6 different power outputs to meet different venues.
2. Intelligent heat releasing design ensures working more quietly.
3. Equipped with both XLR and TRS(6.35mm).
4. STEREO, BRIDGED or PARALLEL output modes.
5. With Signal led, Peak led Protect led and Power led.
6. Protection circuit design, overload/short-circuit/DC protection, temperature control system and peak limit.
7.2U & 3U height design.
8. Class H design.
9. Soft-start.
