INTRODUCTION
The Whirlwind LD410 Line Driver is the ultimate tool for matching 
audio equipment signal levels. The LD410 is both a professional quality, 
sonically superior -10 to +4dB to -10dB level converter and a flexible 
multichannel distribution amplifier within a single rack space enclosure. Each 
of the eight output channels feature gain controls, LED metering and mute 
buttons. There are also eight input channels utilizing the highest quality, low 
noise preamplifiers with14dB input pads that can be engaged to attenuate high 
input signals. The LD410 is factory configured with four channels of 10dB to 
+4dB conversion (RCA input jacks to male XLR outputs) and four channels of 
+4dB to 10dB level conversion (female XLR inputs to RCA output jacks). An 
additional screw terminal block on the rear panel provides balanced signal 
connections for those channels with RCA jacks. Assignable signal routing 
jumpers inside the LD410 permit the creation of multiple distribution 
amplifiers by allowing multiple outputs to receive their signals from a common 
input. The LD410 has an internal power supply, which can be set for 115VAC or 
230VAC by changing internal jumpers.
US Audio has made every effort to ensure that your equipment 
is received in the same perfect condition it was in when it left the 
factory. Please inspect your product for signs of any damage during 
shipping and report them to your dealer so that he can present a claim to
