EK-12 product drawings
EK-12 Product Description:
The EK-12 is a high-power, rugged two-way system with a powerful 12" (310mm) LF driver and a 1.75" (44.4mm) HF compression driver mounted on a continuously directional 90-degree × 60-degree horn. The high-frequency horn can be rotated so that the multi-angle cabinet can be placed both horizontally and vertically. Streamlining the system, it's ideal for applications that require efficient and reliable full-range loudspeakers. It is also suitable for fixed installations and quick movable installations.

LD-600 Product Description:
LD series power amplifiers adopt stable and reliable circuit design; The op amp of the FET input is selected as the front, the common base circuit is used as the inverted phase, and the common collector circuit is used as the output. Stable performance, convenient input and output interface, complete functions. The perfect protection circuit has: over-current protection, output DC voltage protection and self-locking (which can avoid the harm caused to the speaker by repeatedly opening and closing the relay in the critical state of protection), temperature protection, start-up delay and temperature control stepless speed regulation fan air cooling and heat dissipation.

F-150 Feedback Suppressor Product Description
Features:
1. Fully automatic detection of on-site acoustic machinery δ SP system filters the sound, automatic mixing of bass compensation, intelligent high-speed feedback processing, and eliminates the return transmission to the greatest extent in full digitalization.
2. Full-color Chinese display, 2-inch OLED display content is more comprehensive and intuitive.
3. Automatically adapt to the acoustic environment, no need to debug, quickly correct the function, ensure the sound quality, and reduce the delay.
4. One-key setting, making engineering debugging more convenient and fast.
5. When more than 10 microphones are used at the same time, the microphone pickup distance will be effectively increased by 30~150cm.
6. Stereo channel input and output, more compatible with other engineering equipment.
7. Under normal use, the machine does not need to be debugged, and automatically adapts to the acoustic environment (the automatic adaptation process takes about 10 seconds), and the whole system will get an additional gain of 6~15dB.
8. If the sound quality is abnormal in the use environment (after many howls during system debugging), please reduce the volume appropriately, and then press the quick correction button of the machine, at this time, a signal sound of 1 second to 6dB will be randomly generated, and the sound quality will return to normal.
Applicable places: large, medium and small conference rooms, lecture halls, multi-function halls, courts, banquet halls, education systems, etc.
