• QSC Joins Microsoft Teams Device Certification Program

    QSC has recently announced that it has joined the Microsoft Teams Device Certification Program and is working towards completing specific solution certifications aimed at further empowering effective meetings and collaboration with Microsoft Teams Rooms and the Q-SYS™ Ecosystem in larger, more complex room types.

    “The Q-SYS™ Ecosystem has always provided solutions for audio, video and control for a multitude of installations and room types, however it has become critical to our customers to bring the full potential of Microsoft Teams Rooms to these installations,” says Jason Moss, VP of Alliances & Market Development, QSC. “We are thrilled to work with Microsoft to deliver tremendous customer experiences for Microsoft Teams to high-value spaces like all-hands, divisible and training rooms along with specific needs for market verticals that require advanced audio, video and control options.”

    “Microsoft Teams Rooms are deployed in an ever-growing variety of meeting spaces,” says Albert Kooiman, Director of Microsoft Teams Devices Partner Engineering and Certification. “The addition of QSC to the Microsoft Teams Certification Program, will enable our mutual customers to create tailored, premium AV experiences powered by Microsoft Teams.”

    Basic electricity formulas

    Although it not specific to sound, we include this document with some basic electricity formulas. They can be found in any electricity textbook, but we have added them to the DoPA Library for reference.

    Ohm's law

    The most basic formulas derive from Ohm's law, which specifies that the electric current between two points is proportional to the potential difference (voltage) between them and inversely proportional to the resistance between them. The formula is:
    V
    I = ———
    Z


    where I is the current (intensity) in amps and V is the voltage in volts. Since we use alternating current in audio, we have replaced resistance with impedance (Z, and this could also be resistance R), measured in ohms. Clearing Z and V we have these other two formulas:

    V
    Z = ———

    Y-cables, looping audio signals through

    This article will explain loop-though connections and "y-cables" for analog audio signals.

    To obtain one or more copies of a signal (for example, to distribute the signal from a mixer to various self-powered speakers or power amplifiers) we use parallel connections. To do this we simply connect each terminal (pin) of the connectors in parallel. That is, 1 to 1, 2 to 2 and 3 to 3 (or tip to tip, ring to ring and sleeve to sleeve in a TRS connector). When we split a signal in two in this way, we refer to a "Y-cable" or "Y" connection, since the division of a signal in two looks like letter "y". Contrary to what it may seem, a y-cable is not a technically incorrect solution, but a correct way of splitting the audio signal. In fact, when a self-powered loudspeaker system or one channel of...
