Product Usage Instructions

Power Requirements
The FM transmitter requires an AC supply voltage. The AC apparent power consumption is specified in VA. The AC power input is given in watts (W), and the active power consumption is indicated in watts (W) as well. The power factor and overall efficiency are also provided.

Mechanical Dimensions
The front panel width and height are given in millimeters (mm) and inches (in). The overall depth and chassis depth of the transmitter are specified in millimeters (mm). The weight of the transmitter is indicated in kilograms (kg). The cooling mechanism used is forced, with an internal fan, and the acoustic noise level is approximately 56 dBA. The transmitter is designed to fit in an EIA rack.

Audio Inputs
The transmitter has multiple audio inputs. The left/mono input and right input are balanced and have a specified impedance. The input level can be adjusted within a certain range. The MPX input is unbalanced and also has a specified impedance. The SCA/RDS input is available and has its own impedance specification. Optionally, the transmitter can support AES/EBU and TOS/Link inputs.

Outputs
The RF output of the transmitter is available through a specified connector and has a defined impedance. The RF monitor output is also provided, with its own impedance and output level. The pilot output has a load impedance specification. Additionally, there are fuses for various components of the transmitter, including mains, services, PA supply, and driver supply.
