Accuracy of chanels
The average of accuracy betwen chanels is about 0,8 to 2% . In the midle, like about 20k ohm there is 8% accuracy but normal cheap potentiometers has about 30% difference between channels so I rate it very good and precise.

Cheap and great. Better antena may be necessary.
I had to buy better, more powerful antenna instead of what was in package so now it works everytime with no problem. Before you insert SIM card into device make sure it is not protected with PIN code otherwise it will not work. Settings of the device is really easy via SMS commands. Device can also return SMS status.

Very good, definitely recommend.
1 of 1 found this helpful It's very easy to assemble. But for non-electronical known people I recommend assembling it with someone who undestand it. As for the power supply concerns I recommend at least 14VAC it's absolutely minimum because of voltage loss on diode rectifier (-2V). Maybe the best option is to use 12VDC and connect it directly to the output of 12VDC stabilizer. As far as the protection concerns the ON-delay is about 3sec. LED diode is ON during normal use of your amplifier. When there is DC voltage above 0,7VDC the LED diode goes OFF after a few seconds with relay de-energized. With higher DC voltage (1V and more) there is much quicker intervention and relays de-energize instantly. After few seconds when there is no DC voltage present the relays energize back. For this price I can highly recommend this speaker protection. It is very small, easy to use and of course it's "must have" in your amplifier.
