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 SR55. See the "Setting Up and Using
Your Stage 55 Series / Stage 5 Series System" section on page 12 in this manual for more
information about antenna positioning.
2: Volume 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.
3: Audio Meter - This "ladder" display (similar to the VU bar meter used on audio devices)
indicates the strength of the incoming audio signal. When the "0" segment is lit, the incom-
ing signal is optimized at unity gain; when the "+6" segment is lit, the signal is overloading.
When only the left-most "-20" segment is lit, the incoming signal is at just 10% of optimum
strength. If no segments are lit, little or no signal is being received.
See the "Setting Up
and Using Your Stage 55 Series / Stage 5 Series System" section on page 12 in this manu-
al for more information.
4: Squelch control - This control determines the maximum range of the SR55 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 Your Stage 55
Series / Stage 5 Series System" section on page 12 in this manual for more information.
5: ANT A/B LEDs - When signal is being received, one of these will be lit yellow, showing
you whether the (left) "A" or (right) "B" antenna is currently being used. The SR55 con-
stantly scans its two antennas and automatically selects whichever is receiving the
strongest, clearest signal. This Diversity switching is completely inaudible, but it effectively
increases overall range while virtually eliminating potential interference and phase cancel-
lation problems.
6: RF Meter - This "ladder" display (similar to the VU bar meter used on audio devices)
indicates the strength of the incoming radio signal. When the "100%" segment is lit, the
incoming RF signal is fully modulated and at optimum strength. When only the second
most left-most "10%" segment is lit, the incoming signal is at just 10% of optimum strength.
If no segments are lit, little or no signal is being received. See the "Setting Up and Using
Your Stage 55 Series / Stage 5 Series System" section on page 12 in this manual for more
information.
7: Power switch - Use this to turn the SR55 power on and off.
