Lets you attenuate the level of the LFE (Low Frequency Effect) channel output from the sub woofer without effecting the level of the bass frequencies sent to the sub woofer from the front, center or surround channels via the Dolby Digital or DTS bass redirection circuitry.
· For LFE mix level, "0 dB" outputs the full LFE signal at the mix level determined by the recording engineer. · To mute the sound of the LFE channel from the sub woofer, select "OFF". However, the low frequency sounds of the front, center, or surround speakers are output from the sub woofer according to the settings made for each speaker in the speaker setup (pages 1519). XXX
* The parameters can be adjusted separately for MULTI CH IN (HT-DDW840 only).

Notes
Before receiving broadcasts, make sure you have connected FM and AM antennas to the receiver (page 7).
Storing FM stations automatically (AUTOBETICAL)
(Models of area code CEL, CEK only)
· Do not press any button on the receiver or supplied remote during autobetical operation. · If you move to another area, repeat this procedure to store stations in your new area. · If you move the antenna after storing stations with this procedure, the stored settings may no longer be valid. If this happens, repeat this procedure to store the stations again.
Direct tuning
You can enter a frequency of the station you want directly by using the numeric buttons on the supplied remote. For details on the buttons used in this section, see pages 39-45 for remote RM-PP411 and pages 46-49 for remote RM-U306.
Receiving Broadcasts
This function lets you store up to 30 FM and FM RDS stations in alphabetical order without redundancy. If you want to store FM or AM stations one by one, see "Presetting radio stations" on page 33.
1 Press ?/1 to turn off the receiver. 2 Hold down MEMORY and press ?/1 to
turn the receiver back on.
1 Press TUNER on the remote.
The last received station is tuned in.
"AUTO-BETICAL SELECT" appears in the display and the receiver scans and stores all the FM and FM RDS stations in the broadcast area. For RDS stations, the tuner first checks for stations broadcasting the same program, then stores only the one with the clearest signal. The selected RDS stations are sorted alphabetically by their Program Service name, then assigned a 2-character preset code. [. . . ] · Select a stronger FM station.
