NAD 4225 AM/FM Radio Tuner Specification This is an analogue radio tuner, frequencies supported are 522-1611 kHz (AM) and 87.5-108.0 MHz (FM). Tuning is by a rocker switch. With AM, this can only be done manually. With FM, LED indicators under the frequency display (left/centre/right) help to get manual tuning spot-on. With the scan button pushed in, pressing the rocker switch momentarily will cause the tuner to search for the next station. I found this to be a little too sensitive, stopping too frequently, like an all stops train when I wanted main stations only. It has a total of 14 presets in 2 banks. An LED indicator shows either green or amber dependent on which bank is selected. AM is mono only. On FM, if a stereo signal is present and the signal is strong enough, a stereo decoder cuts in automatically, confirmed by a green LED. If the signal is only just strong enough for stereo, theres likely to be background noise (hiss). Pressing mono bypasses the decoder, which usually gets rid of the hiss, but you lose stereo. Pressing blend reduces only the high frequencies to mono, lessening the hiss, while keeping some stereo effect. Aerial connection is by a row of bare wire spring terminals: a single socket for AM, three sockets for FM: earth plus a choice for either 75 ohm (co-ax) or 300 ohm (twin shielded) wiring. There is no co-ax socket. It does not support any digital services, such as Digital Audio Broadcasting (DAB)It does not support and programme information services, such as Radio Data System (RDS) This is suitable for UK 240V 50Hz mains supply only.There is no voltage selector to change input voltage on this particular model. History I bought this new in 1989 and used it until 1997 when I upgraded to a Linn system. The NAD tuner was then packed away in its original box and stowed in the attic for 26 years ... until now! Cosmetic Condition The buttons and switches, the front of the fascia panel and even the acrylic covering the LED display are in excellent condition. Defects are: Minor abrasion on the edges of the fascia where the paint has worn away;Scratches down to the metal on the lid caused by me carrying it with the 13A plug balanced on top;The mains cable was cut to half length to fit a cabinet. I shall replace that before despatch. Ive highlighted abrasions and scratches in the photographs. Functional Condition It works very nicely, all buttons, all lights, all functions. After 26 years, the presets had lost their memory. They keep it when the tuner is connected to the mains, and even when unplugged, they appear to hold it for a few days. The tuner is surprisingly tolerant of a low quality signal using a cheap indoor T aerial. The stereo light came on, though with some hiss. With a proper roof-mounted directional aerial, FM stereo reception is clean and clear. A high end (very much more expensive) valve tuner might have more excitement and sense of ambience, but the NAD 4225 is a great little tuner nonetheless. Live broadcasts on BBC Radio 3 sound natural and very enjoyable. I tested it for about an hour with no issues. Reason for Sale The attic floor is groaning under the weight of stuff kept in case it came in useful again. Im having a clear out. Apart from a cosmetic scratch on the lid and a rather short power lead, this is a nice clean example that deserves to be used and enjoyed. International Post To any international buyers, I am relying on eBays Global Shipping Program for international post. This is where I simply post it to a UK warehouse and eBay take responsibility for the entire shipment from that point on: customs declaration, customs fees, shipping and delivery. I dont get to see or calculate those prices or delivery dates, but you do. I will simply promise to despatch it within 2 days of receiving payment in full.
