An equalizer needs to be connected to the tape monitor loop on an AV receiver in order to operate. The current line of Sony® receivers do not have a tape monitor loop. For this reason, it is not possible to connect an add-on equalizer to current Sony® AV receivers.
- Most Sony® receivers feature a built in Digital Signal Processing (DSP) Equalizer. The addition of an equalizer is not needed, and would provide no additional benefit to the overall sound output of the receiver.
- BOSE® speakers that require an external equalizer are not compatible with Sony® AV receivers.
