Adastra | Compact Beltpack Induction Loop Receiver,Black,12cm

I was going to make one of these but at the price they are I decided to buy. It works well. Very loud and good quality when used with good headphones or ear moulds. It uses a pp3 for a battery and lasts a long time. The volume control works the right way , clockwise to make it louder. The headphone switches it on when you plug it in. The filter should be switched on all the time. Normal hearing aids have the filter on permanently. I don’t know why the filter switch was not used to switch the unit on and off and hard wired the filter on. My wife likes it very much and has to keep the volume about a third up, otherwise it is too loud !

am unable to test properly to date, works ok with radio but computer not so good with a lot of unwelcome noise, still to try person to person

Great piece of kit. Church PA system wasn't catering for those elderly people like me who don't need a Hearing Aid but don't hear higher frequencies so well. This enabled me to connect to the Loop System. It helps me to hear everything very well!

I purchased an Adastra LR2 Induction Loop Receiver in Dec 2018. As with other reviewers, it is working fine to check my church hearing loop. The volume control on my unit works in the usual direction (clockwise for increasing volume) unlike earlier reviews.The supplied earpieces (as pictured) are cheap'n'cheerful but the unit has a standard 3.5 mm jack and a pair of better stereo headphones worked fine. Plugging these in still acts as the on/off switch. My unit was supplied with an alkaline MN1604/6LR61 battery (PP3 in old money).Instructions are still not supplied so read the other comments for these. The front slides up (rather stiffly when new) to access the battery compartment. The battery clip leads are restrained tightly inside the unit making the battery somewhat fiddly to fit.

Does exactly what is says on the tin. Picks up the church induction loop with no problem. The earphones are very cheap and cheerful and fall off my ears rather too easily as they just sit at the entrance to the ear canal. If you are going to use the unit a lot probably worth buying some better-fitting earphones. Also bear in mind that when you plug in the earphones it powers up the unit so remember to disconnect them when you have finished using the unit. It does not have a separate on/off switch which is a bit disappointing. It could easily have been incorporated into the volume control. This is only a minor gripe and as it does not detract from the usefulness of the unit I don't feel it justifies a star less.

I bought this for recording live events in environments in which there is a lot of room reverb and I don't have access to a direct feed from a mixer, so quality matters more than it might as just a test tool. It is susceptible to noise when there's weak or no signal (including during quiet or silent periods) but, given the nature of the technology, that's to be expected.Still, it's not all that bad if the signal is strong (as tested using an earbud as a transmitter held near the pickup inductor). I haven't yet had a chance to test it with a purpose-built AFIL transmitter and have no idea what signal strengths are like in real situations. Perhaps I'm being a bit hard on it given its price point, and the £450 professional receivers might not be much better.My biggest issue with this unit is that it is extremely "microphonic" (physical vibrations get converted to sound) because it uses a really cheap inductor as its pickup. It has no microphone, it shouldn't do that! If you have some basic electronics experience and access to the right equipment, it's not hard to replace with something better quality if you care. Or, just make sure it doesn't get jostled. Just be aware that some of the noise you're hearing could be coming from your belt, clothes or fingers if carrying it in your hand.Unlike other reviewers' units, mine does not switch off when the 'phones are unplugged. Seems I have to disconnect the battery. It's a nuisance, but it's not like this is an every-day tool.As others have noted, the ear buds are poor quality. The 3.5mm moulding on mine was faulty and one of the buds intermittent, but any other headphones or earbuds will do instead.

Easy to use when testing Hearing loops. Good design and the headphones just work.

Bought this to replace an (extremely expensive) equivalent provided with our hearing loop and it does the job fine at 1/4 the price. Use your own headphones, rather than the very cheap and cheerful earbuds provided. Only slight issue was the headphone socket - had to rotate the headphone plug a little to get it going, but did the job of testing the loop.
