Infrasonic Filter Settings
It is a good practice to use a High Pass Filter (HPF) to prevent frequencies below the system tuning fre-
quency from reaching the speaker. Inputting these frequencies to the speaker will not result in any appre-
ciable acoustic output but will put needless mechanical stress on the woofer and reduce available amplifier
headroom. A High Pass Filter will protect your MRX500 system from excess infrasonic energy with little, if
any loss of significant program content. Refer to the above chart for infrasonic filter settings.
