Features: Brand new and high quality Using professional VU driver, the root contains dynamic compression circuit, logarithmic output characteristics, the pointers do not move to avoid the small signal, large signal when the pointers bottom phenomenon. Has a mute function, in an instant start the mute function feet will get a low level, so as to avoid the energizing moment, pointers to the bottom phenomenon. To follow the power in habits, the pointers will be a small swing to swing. The circuit of power AC12V, rather than TA7318 at least DC20V power above, it will be very easy to use. Use of double-sided circuit boards, to ensure the pressure wiring terminal is firm, not many times after the wiring connection boards have loosened. The drive board is designed with beautiful and reasonable layout, without interference and self-excitation phenomenon. Specifications: Material: PCB Size: Approx. 55x66mm / 2.16x2.59inch Voltage: AC12V Pitch of locating hole: 50x56mm Diameter of locating hole: 3mm Note: 1.Please allow 1-2cm errors due to manual measurement, make sure you do not mind before ordering. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
