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.
