High Gain Antenna Kit (Optional)
The Lectrosonics ALP620 shown in Figure 8 is a directional
antenna for increased range and reduced interference.
The "gain" of this antenna enables it to receive signals
from a greater distance than at typical "whip" type
antenna. The antenna allows for increased performance
of wireless microphones with 7 db of gain. The directional
antennas may be located up to 50' (15.2 m) away from
the announcer's rack.
USB Audio Interface
Engineering USB-Pro™ shown in Figure 9
The Radial
®
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
Signal Cables
Cable specifications are as follows:
•
1 pair, 22 AWG signal cable from control enclosure to input plate (part # W-1615)
•
2 pair, 13 AWG speaker cable from cabinet to control enclosure (part # W-3902519)
•
6' (1.8 m) 1/8" to 1/8" stereo audio cable (part # W-3511512)
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 for longer cable runs if necessary. Refer to Figure 10.
•
Run audio cables away from power cables to prevent noise.
•
Audio cables must be kept separate from current loop (scoreboard control) signal cables.
