JBL Stadium Class D / 1000w X 1 w/Remote Level Control

Connectivity: This amplifier can accept low- or speaker-level inputs so it'll work in almost any system, and the package includes screw-on RCA-to-bare wire adapters for the speaker-level signal. JBL has also included their electrical anti-rotational locking (E.A.R.L.) ground terminal, for a more conductive and secure ground connection for the amplifier. The Stadium 1000 sub amp will integrate perfectly and look fantastic in a system that uses the matching JBL Stadium 4 four-channel full-range amplifier..
Mono subwoofer amplifier: 700 watts RMS x 1 at 4 ohms (1,000 watts RMS x 1 at 2 ohms).
Variable low-pass filter (32-320 Hz, 12 dB/octave) / Variable bass boost (0-9 dB at 70 Hz) / Phase switch (0, 180 degrees).
E.A.R.L. ground terminal included / wiring and hardware not included with amplifier / 4-gauge power and ground leads recommended.

...olar panels into usable electricity. Single-phase microinverters are usually used in residential and small commercial environments（Support single-phase or three-phase connection）.
We have improved the AC wiring solution. Configure converters for faster installation. Avoid the risk of miswiring the fire, zero and ground wires.Meanwhile, the DC input is designed with MC4 connector to avoid reversing the positive and negative terminals. (Some customers extend the solar panel cable so that the positive and negative polarity is reversed).
Grid Tie Inverter can monitor in real time the power generated by the inverter through the AC digital meter.（Voltage, current, active power, electrical energy, frequency, power factor）No fire risk and electric shock during installation and operation due to low DC voltage(up to 50V) compared with at least 200V from string inverters.
Grid Tie Solar Inverter suitable for 4X250W-300W 36V solar panel (Vmp30-39V.
Voc = open circuit voltage.Optimized for high powered 60-cell and 72-cell* modules.Each MC4 branch cannot exceed 300W.
Islanding protection.Almost no mainten....

The dental cutting lathe can be used in all kinds of cutting and polishing for various pint-sized metal, resin,or plastic work pieces and craftwork.
It is designed with integrated drilling bit and motor at the same time,and extending the useful time of the drilling pieces.
High rotation speed, fast cutting and griding and low noise.
Note: This unit is applied to single phase AC. So there will be some magnetic induction,this is normal. So power supply coming with ground line is requested, if no ground line, pls help to connect the wire underneath with the ground, then power on it..
Please choose Purple-violet. We are committed to the spirit of "Pursuit of high quality,customers' satisfaction"..
