Guided Tour - UR1 Front Panel
1: Antennas (A and B) - The antenna mountings allow full rotation for optimum
placement. In normal operation, both Antenna A (the antenna on the left) and Antenna B
(the antenna on the right) should be placed in a vertical position. Both antennas can be
folded inward for convenience when transporting the UR1. See the “Setting Up and Using
the Series One System” section on page 8 in this manual for more information about
antenna installation and positioning.
2: AF (Audio Frequency) Level control - This knob sets the level of the audio signal
being output through both the balanced and unbalanced output jacks on the rear panel.
Reference level is obtained when the knob is turned fully clockwise (to its “10” setting).
3: Peak LED - This LED lights yellow when output signal from the UR1 is at the onset of
clipping (that is, when it is on the verge of being distorted). If you see this light during
operation, move the microphone further away or lower the output level of your instrument
or transmitter. For more information, see the section entitled “Setting Up and Using the
Series One System” on page 8 in this manual.
4: A/B Receiver LEDs - When signal is being received, one of these will be lit green,
showing you whether the (left) “A” or (right) “B” receiver is currently being used. The UR1
constantly scans its two antennas and automatically selects whichever is receiving the
strongest, clearest signal. This
True Diversity switching is completely inaudible, but it
effectively increases overall range while virtually eliminating potential interference and
phase cancellation problems.
5: RF (Radio Frequency) Level meter - This five-segment meter (similar to the VU bar
meter used on audio devices) indicates the strength of the UHF signal being received.
When all segments are lit, the incoming RF signal is at optimum strength; when only the
left-most segment is lit, the incoming RF signal is at minimum strength. If no segments are
lit, no signal is being received; check to ensure that the transmitter is on and that it is set to
the same channel as the UR1. See the “Setting Up and Using the Series One System”
section on page 8 in this manual for more information.
6: Power LED - This lights red whenever the UR1 is turned on.
7: Mute (squelch) control - This control determines the maximum range of the UR1
before audio signal dropout. Although it can be adjusted using the supplied plastic
screwdriver, it should normally be left at its factory setting. See the “Setting Up and Using
the Series One System” section on page 8 in this manual for more information.
8: Power switch - Use this to turn the UR1 power on and off. When the receiver is on, the
Power LED (see #6 above) is lit.
