Denon TU-580RD

A slim-line FM/AM tuner with RDS decoding and 30-station memory, built for precise frequency selection and a clear display.

Overview

The Denon TU-580RD is a tuner that covers VHF (FM) and hectometric waves (medium-wave/AM). It has an RDS decoder that shows station names or program types, and you can select from 15 predefined program categories. There are 30 station presets in total, split into three banks (A, B, C) of 10 each. Scanning through the presets only works from the remote control, not the front panel. Self-programming is not supported.

Design

The TU-580RD is a "slim-line" design - very slim in height, but standard size in footprint. It sits on four thick legs with gold rims. The front panel has an average-sized display on the left and rectangular control buttons on the right, including large, easy-to-use tuning keys. Button presses are light with minimal travel, with clear tactile feedback and a quiet click. In low light, the unlit buttons blend into a solid black mass.

Reception & Use

The AM (medium-wave) section has high sensitivity and exceptional selectivity, over 40 dB, plus strong suppression of parasitic reception channels. Real-world MW listening still turned up significant noise, background interference and unwanted signals, especially with external antennas. The internal frame antenna performed acceptably with local, powerful stations. FM reception was excellent. Bandwidth narrowing allows reception of weak stations near strong ones, with slightly reduced quality and lower noise. Minor distortions were occasionally audible on FM during signal bursts, which kept it from a top-tier sound score. Overall performance was rated as good.
