Radial Relay XO Balanced Remote AB Switcher
The Radial Relay Xo is a 1-in, 2-out balanced audio switcher designed to route the output of a microphone to two different audio inputs. This, for instance, 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 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 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 Relay Xo's to be used in tandem.

The Radial Relay... a powerful switcher that is easy to use!

  • JR1 REMOTE - Locking XLR and 1/4" combo jack used to connect the Radia JR1 Remote footswitch. The Relay Xo powers the JR1 Remote LED indicators to provide local visual feedback.
  • REMOTE LINK - 1/4" link output used to expand switching to additional Relay Xo units.
  • MIC/LINE INPUT - Balanced XLR input for microphone or any other audio source. Features locking XLR connector.
  • BOOK END DESIGN - Creates a protective zone around the jacks and switches.
  • 14 GAUGE STEEL - I-beam enclosure makes it imposible to torque the PC board; eliminates cold solder joints from developing.
  • POWDER COAT FINISH - Keeps your Radial Relay Xo looking good for years.
  • CABLE CLAMP - Prevents accidental power disconnection by locking down the AC adapter cable.
  • OUTPUT-A - Main balanced XLR output. This output is active when the switch is in the outward position or when a remote switch is open.
  • OUTPUT-B - Alternate balanced XLR output. This output is active when the select switch is pressed inward or when a remote switch is closed.
  • FULL-BOTTOM NO-SLIP PAD - This provides electrical isolation and plenty of 'stay-put' friction to keep the Relay Xo in place.
  • POWER JACK - Connection for the included 15 volt (400mA) AC power adapter.
  • ISOLATED XLRs - Heavy duty glass-filled XLRs with nickel-silver contacts are stronger than steel.
  • EXTRA DURABLE SWITCHES - With metal outer casing are rated at over 20,000 cycles for added durability.
  • GOLD SEALED RELAYS - Military grade relays are used to switch the audio signal and provide a straight wire signal path.
  • DISCRETE - Full size, hand inserted parts ensure the audio signal flows without impediment from input to output without distortion or artifact.
  • CIRCUIT BOARD - Double-sided military spec for greater durability and full ground plane to reduce radio frequency interference.
  • OUTPUT SELECT - This switch toggles the Relay Xo's outputs. Two LED indicators display which output is active.
  • GROUND LIFT - Disconnects pin-1 (ground) on the input XLR jack to help reduce hum and buzz caused by ground loops.
