IMPORTANT:
Be sure to install a shield between the final stage and the exciter audio stage. Install a good power capacitor in the + 48V power wiring that powers the power output stage. This will keep the power line stable.
Excessive drive level can damage the amplifier; The design of the equipment where the amplifier will be mounted must foresee an adequate protection circuit.
The efficiency of the amplifier depends on the supply voltage, for maximum efficiency, reduce the supply based on the desired output power. In general, the best compromise between efficiency and harmonic emission is obtained when the amplifier operates at approximately 2-3 dB of gain compression.
WARRANTY CONDITIONS
All devices are sensitive if you do not have enough experience in radio frequency please do not handle this product, as they can burn easily if you apply too much input power, too high supply voltage, not using the proper heatsink, using a filter with insufficient specifications , connecting mismatched or no-load loads and also soldering the coaxial cable that is too long or of poor quality. For this reason, there is NO WARRANTY for any amplifier. We assure you that each module is tested and fully operational when it leaves our workshop, in addition a video of the assembly of each one is sent to verify its operation.
The Guarantee applies for 90 days for the rest of the products, with the exception of the amplifier modules.
