If the decoder supports SBR, all four tones, 6, 8, 10, and 12 KHz should be heard (or seen on a sound level meter if you have high-frequency hearing loss). The LFE signal is encoded 10 dB lower to account for the 10 dB gain in the LFE channel in the playback amplifer's bass management circuits. (Hold SLM next to subwoofer) If full-range speakers are used, the 60 Hz tones should play through each speaker individually, though levels may vary due to standing wave or resonances in the listening rrom. If a subwoofer is used with limited-range main speakers, all 60 Hz tones should play at the same level through the subwoofer. There is a 1 kHz -18 dBFS tone in the center channel throughout. SBR - 6, 8, 10, 12 kHz tones -18 dBFS, 0.5 seconds each.
