Crossover Frequency Setting (CROSS)

The deep bass intended for any speaker con- figured as SMALL is redirected to the powered subwoofer or to LARGE speakers based on the settings of the digital crossover in the RSDX-02e. This item determines the crossover frequency. Bass below the crossover frequency is redirected; sounds above the crossover fre- quency are sent to the original speaker. One crossover frequency is used for the entire sys-

tem. Use the CONTROL buttons to se- lect one of three crossover frequencies:

•80Hz: Select this setting for an 80Hz cross- over frequency.

•100Hz: Select this setting for an 100Hz crossover frequency.

•120Hz: Select this setting for a 120Hz crossover frequency.

The selection of a crossover point is largely determined by the capabilities of your speakers. Lower crossover points may improve blend- ing of the subwoofer to the rest of the system. Higher crossover points will increase the power handling of the speakers and the ability of the system to play loudly without less distortion.

As a starting point, we recommend the 80Hz crossover if all of your speakers have a woofer size of 6 inches or larger. Try the 100 Hz cross- over point if your smallest speakers have 5 inch woofers. If any of your speakers have a woofer of 4 inches or smaller, the 125Hz crossover will probably be the best choice. The audible dif- ferences in the three crossover points will be subtle.

NOTE: If you have previously configured all of your speakers as LARGE, the crossover fre- quency item will not appear.

LFE Attenuation Setting (LFE)

Dolby Digital and DTS recordings have a special Low Frequency Effects channel used exclusively for low bass and typically repro- duced by a subwoofer. When played at its standard level, this bass channel can place great demands on a system. This setting gives you the ability to reduce the level of the LFE channel if you hear bass distortion. Use the

CONTROL buttons to select one of two settings:

31

•0dB: The normal setting, reproduces the LFE channel at its full level.

•–10dB:Reduces the level of the LFE channel by 10 decibels.

NOTE: The LFE attenuation setting has no ef- fect with any input signal other than Dolby Digital or DTS.

As a general recommendation, start with the setting at 0dB (the factory default). If you hear bass distortion during loud passages in Dolby Digital or DTS soundtracks, try the –10dB setting. The need for the LFE attenuation will be more likely in less capable systems or sys- tems without a subwoofer.

Dynamic Range Compression (D.COMP)

Dolby Digital recordings are capable of wide dynamic range (the difference between the soft- est and loudest sounds). In some cases, this may tax amplifiers and/or speakers. In other cases, you may want to reduce the dynamic range when listening at low volume levels.

Use the CONTROL buttons to select one of three dynamic range settings:

•MID: slightly reduced dynamic range, roughly comparable to the signal from a compact disc

•MAX: more heavily reduced dynamic range, but still comparable to the signal from a typical VHS Hi-Fi recording.

•OFF: full dynamic range; no compression

NOTE: The Dynamic Range Compression fea- ture ONLY affects Dolby Digital signals.

As a guideline, try the OFF setting for maxi- mum performance with capable speaker sys- tems. If you hear distortion or regularly reduce the volume because loud action scenes are too loud, try one of the other settings. By us- ing dynamic range compression, you can increase the overall volume level to better hear dialog without the loudest action scenes be- ing quite so loud.

Digital Input Assignment (DGT)

The RSDX--02 has two digital audio inputs on the back panel. DIGITAL 1 accepts a coax cable. DIGITAL 2 accepts an optical cable.

These digital inputs can be assigned to any of three source inputs: the STB button, the TV button, or the CDR button to accommodate a variety of systems and cabling options.

Use the CONTROL buttons to the digital input assignments:

•1 STB 2 TV: assigns Digital 1 to the STB input and Digital 2 to the TV input.

•1 STB 2 CDR: assigns Digital 1 to the STB input and Digital 2 to the CDR input.

•1 TV 2 STB: assigns Digital 1 to the TV input and Digital 2 to the STB input.

•1 TV 2 CDR: assigns Digital 1 to the TV input and Digital 2 to the CDR input.

•1 CDR 2 STB: assigns Digital 1 to the CDR input and Digital 2 to the STB input.

•1 CDR 2 TV: assigns Digital 1 to the CDR input and Digital 2 to the TV input.

NOTE: If you assign a digital connection to the CDR input, you should also change the input name from TAPE to CDR. See the topic Changing Input Name.

Automatic Surround Mode (AUTO SR)

The RSDX-02e can automatically activate the proper surround sound mode for digital inputs.

When a Dolby Digital 5.1 soundtrack is re- ceived, DD 5.1 decoding is automatically activated.

When a DTS 5.1 soundtrack is received, DTS decoding is automatically activated.

When a Dolby Digital 2.0 soundtrack with matrix encoding is detected, Dolby Pro Logic II Movie decoding is automatically activated.

When a 2-channel Dolby Digital or DTS source is detected, Stereo mode is automatically ac- tivated.

Use the CONTROL buttons to turn auto surround on or off:

•ON: enables auto surround.

•OFF: disables auto surround.
