with a 3.94" (100 mm) two-way cone speaker and a 0.87" (22 mm) dome speaker. Other
features include:
• Three inputs: one ¼" phone, one RCA, one XLR
• Tone control (High/Low)

Engineering USB-Pro™ (
Figure 14
) 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 15 ) 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.
