6 SSR-100 Components
Single-Muff Headset
The professional single-muff headset (Figure 9) may be used in
place of the standard announcer’s interface wired microphone and
headphones. Other features include:
 Ambient noise attenuation
 Neodymium magnet system for high reproduction precision
 Soft, circumaural ear pads
 Cardioid condenser microphone
USB Audio Interface
The Radial ® Engineering USB-Pro™ (Figure 10) provides an interface
from laptop computers to balanced outputs. Other features include:
 24-bit, 96 kHz quality audio
 Two balanced XLR outputs (left and right)
 3.5mm TRS headphone output
 Ground lift and mono-sum switches
2.4 Signal Cables
Cable specifications are as follows:
 5' (1.5 m) XLR cable for auxiliary audio input (part # W-1627)
 15' (4.6 m) XLR cable between announcer’s interface and rack (part # W-2074)
 25' (7.6 m) XLR cable from rack to fiber box or wall plate (part # W-1560)
Notes:
 Keep unbalanced cable lengths under 6' (1.8 m) to prevent unwanted noise from
being picked up. Use appropriate converters, such as the LTIBLOX Laptop Interface,
to convert to balanced cables (Figure 11) for longer cable runs if necessary.
 Run audio cables away from power cables to prevent noise.
 Audio cables must be kept separate from current loop (scoreboard control) signal cables.
