FEATURES & SETUP- SIDE PANEL SWITCHES: LO FREQ DELAY and HF ATTEN

LO FREQ DELAY- This switch is active only when the amplifier is in BI-AMPmode. This switch controls an additional analog delay which adds to the inherent delay of the low frequency filter. The amount of delay is determined by the SIP programming network installed in the DELAY NETWORK socket (J5). DELAY OFF disables the delay. ENABLE LO FREQ DELAY activates the delay. Refer to the SIP network value selection chart for more information.

HF ATTEN- These switches are active only when the amplifier is in BI-AMPmode. These four switches (section 3, 4, 5, and 6 of the left-most DIP switch) work in combination to control the amount of high-frequency attenuation. The amount of attenuation can be selected in 1dB steps from 0 to 15 dB. Add the selected switch values for the total attenuation. EXAMPLE: Setting -1 dB and -4 dB results in -5 dB of high frequency attenuation.
