7 1.9 INTERCONNECTS These illustrations show various audio, video, and 12V trigger connectors that are used between source components, the A VM 50, displays, and power amplifiers. Note that when RCA cables have coaxial construction and their impedance is 75 ohms, they are equally suitable for analog video and digital audio.
2.1 VIDEO CONNECTIONS The best choice for video connection depends on your display(s) and source components. Any video input can be assigned to any number of Sources. T o configure inputs, see section 3.5 and to configure video outputs see section 3.8.
9 2.2 AUDIO CONNECTIONS There are two methods of transmitting audio signals: Analog and Digital. Analog is an electrical waveform representation of sound and requires one cable for each channel. Digital represents sound using a sequence of numbers and requires only one cable for all channels.
10 2. CONNECTIONS continued … Analog Audio Outputs: Balanced connection offers the highest transmission quality over long cable lengths, because it rejects noise and hum pickup. In the A VM 50, XLR output voltage is twice that of RCA (6 dB higher). The RCA outputs and the XLR outputs are active at the same time.
2. CONNECTIONS continued … 11 2.3 FM • AM ANTENNAS T o connect the AM loop antenna, press the spring-loaded tabs of the AM ANTENNA connector and insert the bare ends of the two wires.
