Radial Relay Xo Microphone Switcher

The Radial Relay Xo Microphone Switcher is a 1-in, 2-out balanced audio switcher designed to route the output of a microphone to two different audio inputs. There is no transformer or buffering circuitry in between the input and outputs. This means the Relay Xo can not introduce distortion or noise into the source signal and allows it to be used with mic or line level sources.

The Radial Relay Xo Microphone Switcher enables a vocalist to switch his mic between the main PA system and the monitors so that he can discreetly communicate with other band members or the technical staff. This is of particular importance for artists that employ in-ear monitors. You can also use the Radial Relay Xo to send the output of a microphone to two channels on the PA. The first channel could be set 'dry' to speak to the audience between sets, while the second channel could be set 'wet' with reverb and echo to enhance the voice. This enables the vocalist to control effects and deliver a more professional performance.

The Radial Relay Xo features a balanced XLR input and two balanced XLR outputs. The audio signal path is completely passive 'pure wire'. There are no transformers or electronic buffers inside that could introduce distortion or color the tone. Instead, the Relay Xo employs military-grade gold-contact sealed relays to do the switching. This makes the Relay Xo equally suitable with mic and line level signals.

Switching may be done using the side-access pushbutton switch or by remote control via the XLR and ¼" input jacks using either the Radial JR1-L latching or JR1-M momentary footswitch. A remote link enables multiple Radial Relay Xo's to be used in tandem.
