My computer doesn't have a serial port - how can I update the Rotel software?
The software for this unit can be updated either through the rear panel RS232 port or over the internet if the unit is connected using the Ethernet connection. If your computer does not have a serial port we recommend using the internet based upgrade which is handled via the setup menu for the unit.

My Rotel has stopped responding to the remote control.
One of the features of many Rotel products is the ability to switch between two completely different sets of IR codes. The purpose of these alternative IR code sets is to allow systems to utilize more than one Rotel device in the same area (for example large multiroom systems that may have centrally located equipment) without conflicting IR codes causing problems. However, on occasion it is possible to accidentally set the Rotel device to this code set which results in the unit no longer responding to the original remote.
To restore the unit to its original IR code set, simply do the following:
- To revert the IR code library from the alternative code set to the original IR library, first press the "Tuner" and "1" button simultaneously on the remote (or "FM" and "1" if your remote is a model that does not have a "Tuner" button).
- Now press and hold the "1" button on the remote control for 10 seconds. The front panel of the Rotel device should display either "RMC : 2->1" or "Audio Code Set 2 ---> 1" to indicate the change. On models that do not have a front display the LED on the volume knob will flash rapidly to confirm the change.
Repeat the above procedure and press “2” key instead of “1” to change the unit to the alternative remote code set.

My Rotel HDMI surround receiver/processor is on and there is video, but no sound.
Check the VIDEO/HDMI menu on the on screen Setup Menu and make sure the unit is set to AMP MODE. If the unit has been set to TV MODE, this setting will Mute all audio output from the receiver and instead routes the sound out the HDMI output to be played through your TV speakers.
If this is a separates system with a Rotel processor and power amplifier, also make sure the 12V trigger switch on the Rotel amplifier is in the OFF position and verify all cables/connections between the processor and amplifier are correct.

Rotel Feature Quick Reference: Signal Sense
Signal Sense is a feature available on several Rotel models and is configured via either the On-Screen Display (where applicable) or front display Setup Menu.
Feature Summary:
- The Rotel device will monitor a specific input for an audio signal.
- If the unit is currently in Standby mode and a signal is detected, it will automatically power the unit up to the signal sense input.
- If the unit is powered on and no signal is detected for 10 minutes, it will automatically power off.
- If the unit is powered off manually (i.e. by the remote control or RS232/IP connection) while the connected audio source is still playing, signal sense will only resume after the audio signal has stopped for a continuous 10 minutes.
- In the original feature design, the Rotel device must be listening to the selected Signal Sense input when it is in Standby mode for the feature to be active. For example, if the unit was configured to monitor the Coax 1 input for audio, and the unit was set to the Optical 1 input when it was powered off it would not power the unit up if a signal was detected on Coax 1)
- With later software updates, most models (excluding RC-1590) now support Signal Sense regardless of the last input selected when the unit is powered off. Using the previous example, even though the unit was last powered off on the Optical 1 input, if a signal was detected on Coax 1 it would power the unit up and select the Coax 1 input.

Signal Sense and the Auto Power Off Feature
The Auto Power Off feature will power off the device if there is no changes made to the volume, source or input within the selected time period.
- The Signal Sense feature takes precedence over the Auto Power Off feature.
- If Auto Power Off is enabled, when the selected Signal Sense input is set for listening, the unit will turn off when there is no audio signal detected for ten minutes, regardless of the time selected for the Auto Power Off setting.
- If an input other than the designated Signal Sense is set for listening, power will be controlled by the Auto Power Off setting.

Should I connect my CD player with the analog or digital outputs?
Which output should be used will matter mostly on the quality of the DACs (Digital-to-Analog-Converters) and the analog signal path in the preamplifier or processor that the Rotel CD player is being connected to. Rotel CD players utilize high quality Burr-Brown or Wolfson DACs coupled with a minimalist circuit design for the analog stage, carefully selecting quality capacitors and rectifiers and providing a solid power supply to provide the best sound quality possible from our CD players, and in many cases the DACs in the CD player will clearly exceed the sound quality of the onboard DACs from many processors. In these cases, the analog outputs of the CD player would be the best logical choice. However, in some cases you may find in a high quality processor or outboard DAC that the DACs used may sound better than the CD players internal DACs, which would mean using the coaxial digital output.
If possible, connect both to your system and compare the two outputs to determine which sounds best in your system.

Should I use an optical (Toslink) or coax digital cable for digital audio?
The debate rages on. Toslink fans claim said cable is more accurate because it relies on light transmission, which has less resistance and is usually more affordable. Coax supporters argue their cable is better protected with its thicker jacket and offers a tighter connection. Interestingly, high quality RCA video interconnects have been substituted for digital coaxial with similar results since video interconnects fit the same specifications used for digital audio. However, do not use a standard RCA audio cable in place of a digital coaxial cable. In the end, your ears are the final judge over which way to go.

Should the analog or digital outputs be used to connect my Rotel DVD-Audio player to the processor or receiver?
To gain the full benefits of DVD-Audio media, the analog connections of the DVD player must be used, and when connecting to a Rotel Surround Processor or Receiver it is recommended that the analog outputs be connected to the 6 Channel Multi Input, as this input is a pure analog input that will not digitally process the high resolution DVD-Audio signal. These players will also internally decode Dolby Digital, dts and PCM (Stereo) digital audio signals as well for DVD and CD playback and as such the analog connection is the only required connection for playback of all formats. A digital cable can also be connected to the processor or receiver for convenience purposes to allow Dolby Digital and dts processing to be handled in the processor without requiring the manual selection of the Multi Input for DVD Video playback.

Should the analog or digital outputs be used to connect the RDV-1040 to the processor or receiver?
A digital cable should be connected to the surround processor or receiver to allow Dolby Digital and dts decoding to be handled in the processor for multichannel playback. The analog audio connections can also be used for stereo playback, for example for CD audio or in a stereo home system.

Switching from FM or DAB radio to Internet radio takes 15-20 seconds for the station to be received.
This is normal - you will find that the product re-acquires your network before being able to select the station that you want, which can take several seconds.
