Guided Tour - SR55 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 conve-
nience 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 position-
ing.
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) indi-
cates the strength of the incoming audio signal. When the “0” segment is lit, the incoming 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 seg-
ments 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.
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 constantly 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 virtu-
ally eliminating potential interference and phase cancellation 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%” seg-
ment 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.
