In situations where the telephone signal is poor , the FK302 two-way amplifier boosts the sound level so that parallel handsets can be accommodated. An 8 Ohm 0.25W speaker is included in the kit. It will also provide a low line-load connection where telephone call interception is required.
Power supply : 4.5 – 9 V DC
Current 160mA (@9 V DC)
Signal level adjustment via Trimmer Potentiometer
PCB Dimensions: 56.1 mm X 37.7mm X 15mm (2.21 X 1.37 X 0.6 in.)
