Radial engineers distribution boxes
Designed by Radial Engineering to provide almost unlimited signal expansion without degradation, the mPress is a press audio distribution system. It is made up of two parts comprising a master host along with a series of external slaves that the manufacturer has named Exo-Pods.
Featuring two mic inputs that are selected via front panel switches with a variable level control high-pass filter, the mPress is encased within a 1U 19-inch rack enclosure and includes two knob limiters for threshold and release. Also equipped are 6.35mm and 3.5mm stereo inputs with a separate level control, enabling the device to be connected to speakers by way of the main stereo XLR outputs.
A headphone output is installed on the front panel for monitoring and troubleshooting, alongside a switch that activates 48V phantom power. Of the balanced outputs incorporated into the mPress, two are situated on the front panel, while the other six are to be found on the rear, with all eight able to be configured with a recessed switch for mic level or high output drive to feed an Exo-Pod.
And of the Exo-Pod, a passive floor box that includes an XLR input and 10 XLR mic outputs, as well as four 3.5mm mini TRS outs. A combined eight Exo-Pods can distribute a signal to up to 112 users, with the ability to distribute to many more by adding additional units. An external lock supply provides the Exo-Pod throughputs with power from the main mPress box.
In other news, Radial has also released the BT-Pro, a Bluetooth direct box that the manufacturer has constructed to convert the signal of a wireless transmission captured from a Bluetooth enabled device into a balanced line for use in a PA system. BT-Pro makes use of the Bluetooth wireless A2DP interface, employing a 16-bit wireless compressed format, while the manufacturer states that Bluetooth connection has been designed to be a simple process.
Housed by 14-gauge steel with an I-beam frame and powered by an external USB power supply, the BT-Pro converts data to a stereo analogue signal, which reportedly produces an output of up to +4dB. A front panel potentiometer controls the signal level and is shared with a headphone amp that has been built-in, while a 3.5mm mini TRS is also fitted for troubleshooting. Two side-mounted switches are equipped to insert isolation transformers into the signal path, complemented by a ground lift switch for the XLRs, and a stereo-to-mono switch is also included.
