Lectrosonics UM400a BLK19 Transmitter

Block 19: 486 to 511 MHz

The UM400a transmitter combines 100 mW of RF output with +/-75 kHz wide deviation for extended operating range and extremely high signal to noise ratio. These key design features are coupled with the compandor-free Digital Hybrid Wireless® audio chain and packaged in the widely recognized Lectrosonics standard transmitter housing.

The unit is powered by a single 9V battery in the internal compartment, or from external DC using a Lectrosonics ISO9VOLT battery eliminator.
