• Radial Engineering BT-Pro V2 Bluetooth stereo receiver

    Canadian manufacturer Radial Engineering has recently announced the availability of its BT-Pro V2 Bluetooth receiver, previewed at last NAMM and basically an upgrade of the BT-Pro, launched in 2015.

    The BT-Pro V2 allows you to add a set of stereo Bluetooth inputs to a sound system, for wireless connection to mobile devices, tablet or laptops.

    Audio quality has improved with the switch to the Bluetooth 5.0 protocol (which extends the data rate to 6Mbps), keeping the existing balanced XLR outputs. A headphone output is provided for troubleshooting, along with a Bluetooth Pair switch that also doubles as a play/pause control. The BT-Pro V2 can be powered using an included adaptor or via 48V phantom power.

    Unlike the original version, each unit now has a unique device ID so multiple receivers can be deployed in close proximity. Also, the latest model of the BT-Pro combines a 14-gauge steel outer shell with an injection-molded insert that improves wireless reception and increases the effective range up to 30 meters (100ft).

    Loudspeaker impedance

    Measured in ohms (symbol, Ω, upper case Greek letter omega), electrical impedance is defined as the opposition to the flow of alternating current by means of presenting an electrical load. In a loudspeaker, impedance varies with frequency, so manufacturers often publish "impedance curves" showing impedance with frequency for passive units. These curves give us... Read more

    Balanced and unbalanced connections

    There are two basic ways to carry an electrical audio signal.

    • The first one is unbalanced. The signal is carried on a two-conductor cable. Unbalanced signal connectors have two pins, such as the RCA (also called Phono and Cinch, commonly used by home hi-fi equipment) and the unbalanced 1/4" (used in musical instruments and semi-professional audio). Multi-pin connectors can also carry
