- Ameritron ARB-704I2
Ameritron Amplifier-to-Transceiver Interface
The ARB-704I2 will work with your all models of the ICOM IC-706 series, the IC-718, and the IC-7000. (PNP-13D is included)
The ARB-704I2 will replace the current series of amplifier interface buffers(702I, 702I2, 702K, 702Y).
The ARB-704I2 advanced interface is compatible with all common radios and amplifiers even though radios and amplifiers do not have standardized voltages, accessory plugs, or wiring. This interface is designed to work with any amplifier/radio combination.
The input is designed to be compatible with any transmitter or transceiver, and the output is compatible with AC control lines or DC positive or negative amplifier control lines having up to 200 Volts peak open circuit voltage and 300 mA of operating current.
The ARB-704I2 operates with transmitters or transceivers that pull amplifier control lines to ground, or output a wide range of positive or negative control voltages. The transmitter only switches currents under .35 milliamperes and very low voltages when using the ARB-704I2. Measures a super compact 4 ¼” x 1 ¾” x 2 ¼”.
The ARB-704I2 is supplied with the following:
1. One power connector cord and plug with red wire (+12 Volts) and black wire (negative and ground).
2. Three phono (RCA) cord with connectors on each end. These cables are for relay, ALC and amplifier control lines.
