- Rotel XS
Rotel XS (eXtended Surround) processing that automatically ensures optimum extended surround performance on 6.1 and 7.1 channel systems. The key benefit of Rotel XS is that it works at all times with all multichannel digital signals, even those that might not otherwise activate proper surround decoding for the center back channel(s). Always active in any system configured with center back speaker(s), Rotel XS monitors the surround channels, properly decodes them, and distributes the extended surround channels to the center back speaker(s). Rotel XS works with matrix-encoded surround signals (such as Dolby Surround EX discs and non-flagged DTSES) as well as non-matrix digital source material (such as DTS 5.1, Dolby Digital 5.1, and even Dolby Pro Logic II decoded Dolby Digital 2.0 recordings) to derive superb center back
channel surround effects.

What type of antenna should I use?
As with other components, specifications are only one indicator of performance. In the case of tuners, including those built into receivers, they are at the mercy of the antenna they are connected to. In fact, most tuners will not even output a signal (such as hiss) unless connected to an antenna. If you find the stock antenna provided with your component yields poor reception, here are some alternatives:
The best possible antenna is the outdoor rooftop variety. Most standard outside television antennas will double as excellent FM antennas. A signal booster may be required if there is a very long run of cable between your roof antenna and the tuner.
A more attractive and effective option over the ubiquitous wall hanging dipole antenna is the indoor antenna, some of which use small amplifiers to boost the signal. You can experiment with placement, but you will probably find best results placing the antenna near a window or outside wall. Keep in mind an amplified antenna will need to be plugged into an electrical outlet. If you have the option of using a 75 ohm coaxial connection over a 300 ohm flat lead, the 75 ohm is the better of the two.

What’s the slopes for the crossover used for the subwoofer?
The low-pass filter for the subwoofer has a –24dB/Octave slope, and the High-Pass filter for small speakers uses a –12dB/Octave slope.

When an input is selected, the front display of the unit displays the name of the input briefly, then changes to something different such as a single character.
One of the features of the RA-1070 and RC-1090 is the ability to rename all of the inputs to a custom input label of your choosing. Chances are, the input labels for the unit were changed perhaps accidentally, and now they are displaying the new label.
To restore all the original input labels a factory reset can be performed on the unit. This can be done by powering off the integrated amplifier, then pressing and holding the following 2 buttons on the front panel – Listening Select PHONO and Recording OFF. Power the unit back on while holding these 2 buttons and the unit will be reset to its factory default settings.

When assembling a home audio or theater system what route should I go - separates or a receiver?
The first question you will face when assembling a home audio or theater system is whether to go the route of separates or a receiver. Years ago, this question was easily answered based on budget. But thanks to Rotel's "balanced design" philosophy, breaking up is no longer hard to do. Of course, if you do not have the space for several pieces of equipment, then a receiver may be your only option. You will also need to take the power requirements of your speakers into consideration.
Theoretically, separates provide better sound. Consider that a receiver has three components all in one box: a tuner (radio), a power amplifier (several if it is a home theatre receiver), and a preamplifier (for volume, tone controls, etc). That's a lot of noise-generating circuitry going on in one box. By having separate components, each one is designed to handle one task, with their own dedicated power supplies, and without interference from the other.
This also makes it easier to upgrade or repair a component. Ordinarily, receivers cannot be upgraded, and if the tuner section breaks, you must bring the entire unit in for repair, creating system down time. Yet if you have a separate tuner which breaks, it can be sent for service but you can still enjoy the remainder of your system while you await its return. And if you find a better tuner that strikes your fancy, changing to the new model is easy, as opposed to living with whatever is built-in to your receiver. Your power will also be limited to your receiver's rated amplification, unless you add an outboard amplifier.
Having said all of that, receivers have come a long way. It could be argued that if you invest in a very high quality receiver, such as Rotel's RSX-1562, you could approach (but not match) the level of separates. A receiver will also require less interconnects and may prove easier to use and faster to set up. In general, if you have the money and the space, seriously consider separates. Otherwise, buy the best receiver within your budget.
When engaging progressive scan mode with certain DVDs, the Digital Direct Progressive LED flashes instead of remaining solid on the RDV-1080.
The flashing Progressive LED indicates the DVD that is being viewed in Progressive scan mode has been filmed from a video source, as opposed to a film source. This is specific to certain DVD titles that are filmed in this manner. It is recommended for these titles to be correctly viewed in progressive scan mode that the Progressive Mode setting on the Preference 2 screen of the RDV-1080’s On Screen Menu be changed to the SMART setting.

When I play a Blu-Ray disc and select the HD audio soundtrack, the display just says Dolby Digital or DTS, but does not say Dolby TrueHD or DTS HD. Why?
In addition to the HD audio soundtracks, many Blu-Ray titles also offer additional audio content in the form of secondary audio, which may include directors' commentaries for example. The secondary audio tracks are usually not encoded in HD but rather in standard Dolby Digital or DTS. Most Blu-Ray players will have a menu option in their setup menu to either enable or disable secondary audio playback. The tradeoff is that when secondary audio is ENABLED, most blu-ray players will not output the HD audio bitstream from discs but instead will play the standard non-HD audio instead. So, to ensure you are getting the full HD audio content from the disc check the setup menu of the Blu-Ray player and ensure the secondary audio option is disabled.

When I play a Blu-Ray disc, the display just says MULTI CHANNEL, but does not say Dolby TrueHD or DTS HD. Why?
If the display reads "MULTI CHANNEL" when playing a Blu-Ray disc, rest assured the Rotel processor is still receiving an HD audio signal from the Blu-Ray player, it is just being received in the form of a multichannel Linear PCM signal instead of the raw Dolby TrueHD or DTS HD bitstream. All HD signals, whether it be Dolby or DTS, first come off the disc as an HD bitstream which must be decoded and uncompressed into raw digital audio (Linear PCM). This first step of decoding and uncompressing the audio can be handled either in the Blu-Ray player or inside the processor and there should not be a noticeable performance difference based on where this occurs. With HDMI 1.1 devices the decoding must occur in the Blu-Ray player, but starting with HDMI 1.3 the raw bitstream audio can be sent to the processor.
Check the settings in the Blu-Ray player's setup menu for an option to set the HDMI audio from LPCM to Bitstream to let the Rotel processor do the HD decoding. This option will only work with HDMI 1.3 and higher devices so RSX-1058 and RSP-1069 must use LPCM only.

When I play a Blu-Ray disc, the display says Dolby HD +XS or Dolby HD +EX, or Dolby HD +PLIIx M/C. Is the unit playing the HD audio correctly, and what does the XS/EX/PLIIx mean?
Yes, the unit is decoding and playing a Dolby TrueHD signal when the display reads "Dolby HD +XS", etc. Many of the HD soundtracks available today are recorded in 5.1, not 7.1. However, if you have a 7.1 audio system you likely will want all 7 speakers (and subwoofer) playing when you listen to a Blu-Ray disc. When this is the case, the Rotel processor can apply additional processing to the 5.1 HD signal to matrix out additional channels for the 6th & 7th channels in the system. You have a choice of 3 or 4 distinct methods to do this:
- Dolby Digital EX (Available for Dolby 5.1 modes only)
- Dolby Pro Logic IIx Music
- Dolby Pro Logic IIx Cinema
- Rotel XS (Extended Surround)
Using these additional processing modes does not compromise the original HD content for the 5.1 channels; it simply allows you to add the extra back channels when playing these 5.1 soundtracks.
For more detailed information on these different modes, refer to the owner's manual for your product.
