The CA-370 amplifier is a modern small home amplifier for receiving TV / FM / DAB signals with two outputs with output levels of 110 dBµV. It is suitable for use in family houses and for multiple housing units. The amplifier is compatible with LTE700 (it has a built-in 5G filter), it amplifies the UHF band only up to 694MHz. The amplifier is made in a compact ZAMAC casting, which has excellent shielding effects, which prevents signal radiation and leads to greater stability of the amplifier. The amplifier has three inputs for the bands: 1 x (40 to 70MHz + 88 to 108MHz + 160 to 260MHz) and 2 x 470 to 694MHz. The inputs are solved in bands with a possible power supply of the preamplifier at the UHF1 input with a supply voltage of + 24V, which can be connected by a switch. The gain of all inputs is adjustable. The amplifier has two main outputs as well as a test output that allows the amplifier to be checked and adjusted without disconnecting STA users. The power supply of the amplifier is solved by an external switching power supply FF-300, 24V / DC, which is part of the delivery.
