My NAD C720BEE 2 ch. receiver has a button on the front panel labelled "Blend". The helpful NAD manual says to use this button to enable or disable the "blend" feature :confused: Does anyone know what the "blend" feature actually is supposed to do?

    I have an old Adcom GTP-400 tuner/pre-amp, and it also has a "blend" feature for the tuner. I'm guessing this is NAD's as well, for the tuner?

    Generally it's a high-frequency blend (filter) for FM. It essentially mixes the HF to mono, eliminating all of the out-of-phase (stereo) noise, while allowing some stereo separation at lower frequencies (where you can "hear" it). This extends one's ability to listen to lower-signal-strength FM without switching to mono.

    Automatic HF blend has IIRC become pretty common on most car FM tuners in recent years.

    ^ MHardy is right, I just checked the Adcom's maual, and that is it exactly. I never used that feature myself though.
