33. you set the crossover is very subjective and can be fine tuned to match your listening preference or speaker requirement If the amplifier is driving small speakers crossover set to PASS or ON the tendency is to set the frequency higher to eliminate the low frequencies from damaging the speaker If the amplifier is driving large subwoofers crossover set to LO PASS the tendency is to set the crossover frequency low These are only guidelines because setting the right frequency depends on the listeners preferences What sounds good to one may not sound good to another The following guidelines should give you a good understanding for working with our amplifiers HI PASS When using the amplifier to drive high and midrange speakers you will need to set the switch to HI PASS or ON depending on the amplifier model When using the amplifier to drive 4 speakers or smaller a crossover point of 150 Hz or higher is recommended When using the amplifier to drive 5 6 speakers a crossover point of 80 Hz or higher is recommended Once set listen to material that you are familiar with before making any changes LO PASS When using the amplifier to drive woofers the switch will need to be set to LO PASS Although it is very subjective when using 8 woofers or smaller a crossover point of 150 or below is recommend ed When using 10 woofers or larger a crossover point below 100 is usually preferred If you are using good mid bass drivers like the NEW
