To avoid undesirable noise, direct boxes (DI Box) take an unbalanced, high-impedance signal and convert it to a balanced, low-impedance signal. This allows instruments directly connect to microphone preamplifiers, and send signals over extended cable runs or into the mixing console in the studio. The benefit of Direct Box is it reduces noise to produce a cleaner sound.

We guarantee that our power sequencers support a variety of operations such as voltage and switch control.

Sometimes a sudden power failure can damage equipment or a device's sensitive electronic loads. Therefore, in the event of a grid outage, an uninterruptible power supply (UPS) must be used to provide near-instantaneous power to the equipment.

We wish your device can be long-lasting accompanied by our UPS product.
