USA - Chauvet has introduced the SF-4005 channel timer, a multi-tasking 2 or 4-channel timer/chaser designed to keep your lighting effects from exceeding their recommended duty cycle. Chase or sound-activated modes are also ideal for pin spots, Par cans and any other chase-able lights. A three-position switch controls timer, chase and sound-activation functions, while another switch lets you select two or four channels for timed control of up to four lighting effects.
