it_ITYamaha THR full power on battery supply
The Yamaha THR wireless amplifiers, when powered by battery, reduces the power delivered. The THR30 decreases to 7.5 + 7.5 watt from the initial 15 + 15 watt while the THR10 descends to 7.5 + 7.5 watt from the initial 10 + 10 watt.
The power reduction allows us to play for a reasonably long time when not connected to a power supply. Yamaha declares 5 hours of autonomy even if according to my estimate there are about 2 hours after testing the sound to adapt to your environment.
2 hours of autonomy is not a bad result, but in a live outdoor context it may not be enough to support the entire duration of a performance, also the power decrease will prevent us from reaching an audience at a distance.
I managed to create a mod to connect our amplifier to a cabinet, extending its use for large outdoor spaces, beyond the classic home use for which it was originally designed, check out the links to see my video step-by-step mod or the full article here on the website.
To avoid the loss of power and extend the autonomy of the batteries, you should always have a power socket to hand, or use the method explained below, which can also be used on the thrs that do not have an internal rechargeable battery:
Use a power bank with adequate specifications in terms of power supply (15 Volt dc), power (65W), capacity 15600 mAh (which extends the use of the amplifier to more hours than one would normally be able to play), which also has the possibility of connection via DC pin 6.0×4.25mm (used on the original Yamaha power supply) and finally, does not turn off automatically when not in use, which is the case when the internal battery is fully charged.
Once connected you will see that the power indicator light will go from red (battery in use) to green (battery charging) restoring the full power of the amplifier, also adding hours of autonomy!
The use of this great power bank is not limited to the simple connection of a thr but will enable you to recharge all of your devices using the a and c usb sockets, to power a laptop, thanks to the multitude of DC plugs it has, and also power multi-effect foot pedals or mp3 players.
See you soon with a new video, ciao everyone!
