Self-Powered Monitor Speaker
The Yamaha MSP3 monitor speaker (Figure 13) features a compact bass
reflex cabinet, 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)
USB Audio Interface
The Radial ® 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.
