The SQ1G is the latest evolutionary step in a process of design refinement that goes back over 40 years to the earliest KLARK TEKNIK graphic equalisers. The enhanced Proportional-Q response recaptures that of the classic single channel DN27 graphic equaliser using modern solid-state design and manufacturing technoligies, and the SQ1G features dual channel 30 band graphic equalisation with fixed high-pass and low-pass filters per channel. The SQ1G provides the essential features for corrective equalisation and filtering in a cost-effective package, without compromise on audio performance, and is ideal for both Front of House and stage and monitoring applications, where both the gentle contouring and surgically precise high-Q notches uniquely made possible by the Proportional-Q response enhance intelligibility as well as eliminating sub-sonic rumble, room and speaker resonances and standing waves.
