Rotel RSP 1582: Carefully designed AV processor

Rotel engineers spent two years carefully designing the RSP-1582 and analyzing the list of required features, striving to achieve the best possible audio and video quality for home entertainment systems. The Rotel RSP-1582 AV processor received a 7-inch TFT display installed in the center of its front aluminum panel.

With its help, you can make all the necessary audio/video settings without using an external screen. Below that, there’s an HDMI input with support for 4K video pass-through and a USB port compatible with Apple devices. To the left of the display there are cross-shaped menu navigation buttons, a power/standby key with LED backlight, an input selector, a menu button, etc. On the right is a volume control in 0.5 dB increments and three function buttons.


The Rotel RSP-1582 AV processor is equipped with six Wolfson WM8740 (24-bit/192 kHz) DACs – four separate chips for the center, front and subwoofer channels, as well as two chips for the surround channels. To work with multi-channel audio tracks, a Texas Instruments Aureus TMS320DA808 signal processor with a 10-band parametric equalizer is used. There is an analog-to-digital converter TI PCM1804. Major surround formats are available, as well as Dolby TrueHD and DTS HD Master Audio. At this stage, the latest Dolby Atmos and DTS:X are not supported, but in the future with the release of new firmware such an opportunity will appear. The built-in Bluetooth receiver with the aptX codec allows you to provide high-quality sound from audio received from mobile devices. There is a Bypass function to bypass signal processing circuits in order to obtain pure analog sound (stereo).


Rear panel inputs: 7 x HDMI with support for 4K video pass-through, 7.1 channel RCA, balanced XLR, 6 x line RCA, phono input (RCA), three each optical and coaxial, asynchronous USB (24 bit/192 kHz). The Silicon Image Sil9573 (2K/4K) chip is used as an HDMI transceiver. There is also a LAN port for connecting to a local network and controlling the AV processor via IP. Outputs: Two HDMI (with 4K video pass-through support, one with ARC and CEC control), 7.2ch XLR and 8.2ch Pre Out (RCA). There is an RS-232 interface, three trigger outputs, an IR input and a pair of output jacks, and a connector for bus control.
