Michi Bluetooth 5.1 aptX™ HD Module

Technical Service Bulletin

Michi Bluetooth 5.1 aptX™ HD Module 

The latest Apple iOS version (including OS V15.7.2) may cause the APPLE MUSIC app to stop playing audio when manually jumping between tracks in a playlist.  The Bluetooth connection is maintained but there is no audio output and no playback information (sample frequency and/or bit rate) displayed.  A hard power cycle of the unit remedies this issue. 

Earlier versions of iOS do not appear to have the same issue.  Other iOS Apps (i.e. iTunes, Spotify, Tidal, etc.) are NOT affected by this use case.

If this is reported, please contact Rotel at sales@rotelglobal.com to order a new Bluetooth 5.1 module (Rotel Part Number: 093E-BTM0002-D-3) with updated firmware V1.04 (or newer) that resolves this iOS compatibility issue.  

Note: All new delivered spare parts will be programmed by new firmware V1.04 (or newer) before package and shipment from now on, either of below two methods can help to identify this change.

1. Check and ensure a printed label with text "V1.04" being pasted on plastic package.
   
2. Or check and ensure the last 5 digits on the pasted BT ADDRESS label are higher than "28780".
   

Bluetooth module replacement requires removal of the top cover and replacing the Bluetooth module in the socket (no special tools or soldering is required) as shown below.

Affected unit models include: X3, X5, P5, X3 Series 2, X5, Series 2, P5 Series 2

FAQ’s -Rotel Wired IR Connection Function and Requirements

Most of Rotel products provide one 3.5mm mini-jack to receive command codes from industry-standard infrared receivers via hard-wired connections. This feature could prove useful when the unit is installed in a cabinet and the front-panel sensor is blocked.

Q: Where is the 3.5mm mini-jack on the unit?

The 3.5mm mini-jack is located on the EXT REM port of the rear panel.

Q: What’s the IR protocol used for Rotel products?

Most current Rotel products use NEC Hex codes as their standard IR library, the base hex library used for most receivers, preamps and integrated amps is NEC 8311, and current Rotel CD players is NEC 8312.

Q: What’s the NEC Protocol?

The NEC IR transmission protocol uses pulse distance encoding of the message bits. Each pulse burst is 560µs in length, at a carrier frequency of 38k Hz. A logical "1" takes 2.25ms to transmit, while a logical "0" is only 1.12ms.

Q: What’s the carrier frequency of the external IR receiver can be used for Rotel products?

Carrier frequency of external IR receiver that works with 38k Hz.

Q: How to connect the Rotel External IR Remote Control?

For standard Rotel products with IR Remote Input require power to the IR Receiver then convert the wireless IR signal to a wired data stream connected to the IR Remote Input on the device. 

Below picture shows that External remote connection needs Power Adapter, Connecting Block (IR remote transceiver), IR Receiver (3 pins for power, ground and receiving IR) and one piece of 3.5 mm Plug Shield Cord.

Q: How to choose a Plug Shield Cord?

A 3.5 mm Plug Shield Cord 2-pin or 3-pin cable is required for connection to the Rotel unit for external IR remote connection.

How do I configure Rotel to operate with Roon?

For best performance and the highest streaming quality set the Rotel unit to use USB Audio Class 2.0 from the front setup menu.  This will require installation of the Rotel USB driver on Windows based computers (no driver required for Mac) and a reboot of the computer and power cycle of the Rotel device.

You can find more information about installing the Rotel USB driver on this page: Rotel USB Drivers

There is also an article with information on how to contact Roon Technical Support at https://help.roonlabs.com/portal/en/kb/articles/faq-how-to-contact-roon-technical-support.

Can I connect my computer to my Rotel system for audio?

Yes - if your Rotel product has a back panel input labeled "PC-USB", you can simply connect your computer to this USB input using a standard USB cable. The computer should then recognize the Rotel system as an audio device and you can then play music from your computer through your Rotel system. Do note that you may need to select the speaker as the primary output device for the computer.

  • For windows users this can be done by Navigating to Start -> Control Panel -> Sound and Audio devices -> Playback.
  • Mac OS X users should navigate to System Preferences -> Sound -> Output.

If you have a Rotel product that does not have a PC-USB input, if your computer has analog or digital audio outputs you could connect your computer to a Rotel receiver or surround processor using one of the analog or digital inputs as you would connect any other source component such as a DVD player or CD player.

Or, for even better sound quality, add a USB DAC to your system such as the RDD-1580. The RDD-1580 features a rear panel PC-USB connection that can be used to connect your computer to the system for high quality audio playback. The DAC would then connect to your Rotel system using the analog output of the DAC into an analog input in the system.
