The CONTROL PORT of the Dx46 provides five control inputs and a reference connection for ground. The control
inputs can be activated using external switches, pushbuttons or relays to connect them to ground potential, see fol-
lowing example.

PORT
Connecting the Dx46 to a PC for operation via IRIS-Net application can also be accomplished via the front panel
USB port. The port conforms to the USB 1.1 Type B specification. Type B USB cables are readily available at com-
puter dealers. According to USB specifications, the cable which is connected to this interface must not be longer
than 15' (5 meters). The USB interface of the Dx46 is a USB B (female) connector.

ONNECTION TO MPLIFIERS
It is very important to confirm correct connection to all amplifiers. The Dx46 has the ability to configure each output
for a specific frequency range; sub, low freq, mid freq, high freq. You must make sure that each output is connected
to the correct amplifier and loudspeaker(s). Incorrect connections could lead to unexpected results or damage to
loudspeaker components. Note also that each preset in the Dx46 includes DSP and bandpass parameters for the
output channels. It is possible for a new preset to change an output from Hi to Sub, for instance. Make sure that
connections to amplifiers and loudspeakers are correct before using a new preset.

The final step in setting up, installing and connecting the Dx46 is to set proper input levels to the unit. The Dx46
does not itself have input level controls. Proper input level setting is accomplished by setting the output level from
the (L / R) bus outputs from the connected mixer (or other audio output device). The input meters monitor the input
level of either analog or AES/EBU inputs, depending on the input mode selection set in the Setup Menu. Optimal
signal-to-noise performance is obtained when the nominal (average), input level consistently lights the +6dBu
(green) and +12dBu (Yellow) LED indicators. As the Dx46 is a digital audio device – and digital clipping produces
very unpleasant results – the Clip (red) LED should never light. If it does, reduce the output level of the connected
mixer.
Input levels to the Dx46 can be reduced 6dB to compensate for higher-level output from mixers and other audio
devices. For ideal signal to noise performance when connecting the Dx46 to high output level devices, engage the
6dB PAD rather than turning down the output of the connected device.
