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.
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
The pass-through feature allows the audio signal from a Surround Receiver or Processor to pass through a separate stereo preamplifier without any signal modification. This is useful if you have a high-end two-channel system but want to watch video with surround sound on occasion.
To use the Bypass mode on the RC-1580, plug the front channel output of the surround sound processor into the Tape 2 inputs. When the Tape 2 input is selected, the signal from the processor is sent directly through the preamplifier and by-passes the tone and volume functions. Once the unit is in bypass mode, the BYPASS indicator on the front panel is turned on.
Setting a system up this way provides a way to integrate a stereo amplifier to be used as the front channels of a surround sound system. Only the Tape 2 input can provide the bypass function. It requires no additional setup, making it easy to switch between normal stereo mode and surround sound mode by using the input selector.

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.
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

Release Notes |
In a small number of units of the Rotel RB-1590 power amplifier, the JRC NE5532 OP AMP used exclusively in the XLR Balanced input circuit have been found to go faulty and may cause a white hissing noise on the RIGHT channel. The noise is exclusive to the XLR inputs and does not affect the RCA inputs. The OPAMPs are mounted in the XLR input stage. Locations are IC500 and IC501 as below: If this issue occurs, we recommended replacing these with an alternate Texas Instruments OPAMP NE5532AP (Rotel Part Number: 031IC0008802 R/IC NE5532AP OP AMP DIP) to eliminate the issue. |
