The signal flows in one direction only – from output to input. mic level, line level, loudspeaker level). Signals are classified by the magnitude of this voltage (e.g.
The signal is in the form of a time-varying analog voltage that can span a level range of over 100 dB. It is not permissible to “Y” multiple outputs together. It is often permissible to passively split an analog output to drive several inputs.
An “output” simply connects to an “input” – end of story. For example, a 100 ohm output would produce the exact same signal level into any high impedance input (10kΩ, 20kΩ, 30kΩ, etc.). The impedance mismatch simplifies the interface by (usually) eliminating the need to consider specific impedance values. The interface is impedance mis-matched, where a low output impedance (typically 2000 Ω). It is electrically balanced, which provides strong immunity to EMI.
DIGITAL TO ANALOG AUDIO CONVERTER TARGET PROFESSIONAL
While similar in many ways to consumer I/O, professional are more robust against electromagnetic interference (EMI) and allow much longer cables – both requisites for large sound systems.įigure 1 – An analog interface is point-to-point, with no exact requirements with regard to cable type, connector type, and cable.Ī professional analog interface is a point-to-point connection between an output and an input (Fig. I will focus on professional interfaces only. In this overview, I will start with analog since it is familiar to most readers and serves as a reference for the discussion of digital formats. The choices may seem confusing at first, but when you break them down the strengths and weakness of each become apparent. How do I get an audio signal from one to the other? The ongoing evolution of professional audio has produced a number of viable digital interfaces to complement legacy analog I/O practices. digital interfaces.Īre you new to digital audio? Are you confused by the landscape of formats that have emerged in the marketplace? Following is a short expose that may shine some light on this potentially confusing topic.
