  • Notes

  • The Model 55SW Microphone is of the multi-impedance type. Model 55SW may be connected directly to a 30-50 ohm line, a 150-250 ohm line or high impedance input. Selection of these impedances is accomplished by changing the position of the switch at the rear of the microphone. The switch positions are marked as "L" for low impedance (30-50 ohms), "M" for medium impedance (150-250 ohms) and "H" for high impedance (35.000 ohms).

    Model 55SW has built-in “ON-OFF” switch to control microphone circuit. The switch is an integral part of the receptacle assembly and is a slide-to-talk locking type switch.
