Features:

·High and low frequency responses are balanced with a flat frequency response
·High and low frequency speakers’ power distribution regulation gives full play to each unit output energy
·High frequency speaker will be protected at low frequency
·Effective reduction of system distortion
·The high and low frequency responses go with each other harmoniously.

TAC350,TAC800,TAC1200,TAC2000 time-control electronic frequency dividers are circumambient and specially utilized to do electronic frequency dividing to sound signals in multi-channel cinemas. Each frequency divider has left, center, right three separate channels, used for left, center, right three groups of speakers in the theater. According to the cinema stereo sound reproducing requirements, the high frequency network is equipped with gain control. The steady enhancement of high frequency is 13dB. Moreover, since low frequency network has 5-section time controls of 3ms, the TAC-series frequency dividers can make 5 stages physical time adjustment to the high and low frequency dividers from the different in location of most main speakers, so as to realize the phase balance of the high and low frequency speakers. As the multi-channel switch frequency is 350Hz, 800Hz, 1.2kHz and 2.5kHz and the switch slope is 24dB, the high and low frequencies go with each other harmoniously.
