• QSC Announces Acquisition of Attero Tech

    QSC announces the acquisition of Attero Tech, effective September 30, 2019. This combines the rapidly growing portfolio of the Q-SYS audio, video and control (AV&C) Ecosystem with Attero Tech's portfolio of networked AV endpoints and I/O peripherals, as well as boosting QSC's development capabilities with Attero Tech's Fort Wayne-based engineering staff joining the multi-national QSC team.

    "This acquisition is a natural next step for our organizations given our long relationship, highly compatible portfolios and the exceptional shared values and company cooperation that have developed over the last several years," says Jatan Shah, Chief Operating and Technology Officer, QSC. "Both QSC and Attero Tech were early adopters of network audio transport technology, including CobraNet, Dante and AES67. In addition, when QSC expanded the control capabilities of the Q-SYS Ecosystem in 2017, it allowed Attero Tech to become the first manufacturer partner to independently develop Q-SYS Control integration plugins, and has since developed 20 plugins for their portfolio of I/O devices."

    "A primary guiding principal of our Q-SYS product development strategy has been a protocol agnostic, software-based approach utilizing the best hardware available, combined with innovation at the software and application layer. This approach allowed us to deliver a standards-based, powerful, flexible and scalable AV&C platform unlike anything on the market," says TJ Adams, VP, Systems Product Strategy and Development, QSC. "Adding the Attero Tech peripherals to the greater Q-SYS Ecosystem will expand existing options for integration end points today, and enlist this new engineering talent pool to accelerate the pace of future software innovation and native end points for the platform."

    "Attero Tech has grown to become the premier provider of innovative, cost-effective audio networking I/O endpoints and AV connectivity solutions," says Rus Sundholm, President of Attero Tech. "Our catalog of products have a well-earned reputation as highly robust, innovative products within the AV industry. We are excited and confident for the future of our combined organization."

    Joe Pham, President and CEO, QSC, says, "This is such an exciting time for QSC and I am thrilled to welcome the Attero Tech team to the QSC family. We look forward to executing an integration strategy that prioritizes the needs of our customers, incorporating Attero Tech into QSC sales, support, service, marketing and training for our channel, while always striving to ensure and maintain a positive experience for our customers."

    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...
