This universal NF amplifier can be combined with all sound units. It is delivered in shrinked plastic tube, with a pre-installed mounting rail. Installation on a metallic surface or in a airstream is necessary for additional cooling.Basics:
The amplifier can be used with one or two speakers
It is recommended to mount the amplifier with its heatsink at a metallic surface to get
additional cooling.A electric isolated installation is not necessary.Use washers between heatsink and surface to get a good thermal contact.The amplifier can be mounted in vertical or horizontal orientation.
Overtemperature protection integrated

A fantastic Amp to use for your TBS Micro unit. Good sound and high power! Amp will get hot depending on load so memory heat sinks are recommended for better cooling. Also makle sure to put in a spot where cooling is at a maximum. I have 4 of these and not one has failed yet. Highly recommend these.
Please visit my youtube channel for reviews on these systems.
Yo lo tengo montado con un sistema de sonido TBS Mini, tambien de HK.
Por el precio que vale y el integrado que susa, no deberia valer mas de $10...lo peor es que con los altavoces que dicen se deben conectar a este amplificador, pues, no escucho mas que el sonido del motor y la helice.
Har pruebas con otros amplificadores de mas potencia.Bought the complete system here. Everything works great.
The amp needs an heat sink and/or to be placed in air flow because it goes very very hot. You must use 4Ohm speakers with a power >40W for optimal performance.Unfortunately mine arrived dead. There was virtually no volume from it and the volume pot made the sound go all static then stop. I'm returning it & will post again when the replacement arrives. I guess with all electronic goods, sometimes a dud happens. I can see the potential for an awesome unit though.I have it installed on my Pilatus porter.
It's lound but get very hot.
Need ventulation or large heat sink.
4 Ohm speaker is suitable for this amp.I am not happy. I got the product but it did not include instructions in English. I have no idea how to install this without instructions in English. Please provide instructions in English.....bardzo dobry wzmacniacz jak na razie dziaawow realy work , i just put heli sound on my mp3 whit a 3 inch speaker and it work.Got mine and it was DOA. Sent back but have not received any information back.
