The Cloud Electronics CV4250 is a remarkable four-channel 70/100V digital DSP amplifier from the CV-Digital series. All models in this series can deliver a total power output of 1KW, which is distributed across the amplifier channels. This flexibility enables a single multi-channel amplifier to drive speaker systems with different load sizes in various areas of a building or venue while optimizing the overall power output. Key features include: direct drive of 70V/100V line systems without a transformer, thermal protection, overcurrent limiting, DC offset protection, a switch-on delay to protect speakers during power-up, and front-panel LEDs for each channel to show signal presence, peak level, protection activity, and power status. Technical specifications: Net dimensions are 482.6 mm x 88 mm x 381.8 mm (19 in x 3.46 in x 15.03 in), shipping dimensions are 606 mm x 164 mm x 558 mm (23.9 in x 6.5 in x 22 in). Net weight is 7.26 kg (16.26 lb), shipping weight is 9.26 kg (20.74 lb).
Using the Cloud Electronics CV4250 amplifier is easy. First, make sure to connect your speaker systems correctly to the appropriate channels. The amplifier can directly drive 70V/100V line systems, so there's no need for a transformer. When powering on, there's a switch - on delay to protect your speakers, so just turn it on and wait a bit. Check the front - panel LEDs on each channel. They'll tell you if there's a signal, the peak level, and if the protection is active or the power status. For safety, avoid overloading the amplifier. The thermal protection, overcurrent limiting, and DC offset protection are there to keep things running smoothly, but don't push it too hard. To maintain your amplifier, keep it in a well - ventilated area to prevent overheating. Wipe it down regularly with a dry cloth to keep it clean. If you notice any abnormal behavior, like strange noises or the LEDs showing unusual status, turn it off and seek professional help.
