Our 8-point functional test was completed in full: all checks passed except no hum. Note: The amplifiers are in good working order, but there is a constant high-pitched buzzing sound whenever they are plugged in. Audio still plays through fine, but the buzzing is definitely present. Cosmetically, there are quite a few surface marks and scratches throughout, though nothing that affects the overall appearance of the amplifiers. Please review all photos carefully, as they provide an accurate representation of the cosmetic condition of the product.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eAdastra UM30 (Black)\u003c\/li\u003e\n  \u003cli\u003eNo additional accessories included\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAbout this model\u003c\/h3\u003e\n\u003cp\u003eThe Adastra UM30 is a compact 30W mixer-amplifier built for public address and commercial audio installations. It uses Class D amplification with a transformer output and can drive either a 100V line or 8 ohm speakers. Inputs include a 6.3mm microphone jack, RCA line inputs and a 3.5mm aux jack, alongside built-in Bluetooth, FM radio and USB playback. Mono speaker output is via screw terminals, with a line output and 24V DC terminals also provided. At 249 x 210 x 44mm and 2.35kg, it is slim enough that two units fit side by side in 1U of 19\" rack space.\u003c\/p\u003e\n\n\u003cp\u003eA great opportunity to own a Adastra UM30 at this price point.\u003c\/p\u003e","brand":"Adastra","offers":[{"title":"Default Title","offer_id":55226708492625,"sku":null,"price":69.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0775\/6913\/0833\/files\/b9a3854d-aa73-4fa0-9cae-0bce6c5061b4.jpg?v=1791469310","url":"https:\/\/www.audiotrader.co.uk\/products\/adastra-um30-power-amplifier-black-good","provider":"Audio Trader","version":"1.0","type":"link"}
