Housed in single-rack-mount chassis, the 240 and 241 are each equipped with a two-input, four-output Euroblock routing configuration. Both units have a comprehensive menu of features, including a 31-band graphic or 9-band parametric pre-EQ on each input, two-band parametric post-EQs on all four outputs, compressor/limiter, post delay of up to 330 milliseconds, and output phase compensation. Crossover options further include a choice of Butterworth, Bessel and Linkwitz-Riley types.
