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.
