4. Installation
Safety Instructions for Installation
Attention
Make sure there is enough space for ventilation around the device.
Do not install near equipment that produces heat, for example amplifiers.
Installation Site Requirements
●The device must be installed only indoors.
●The device can be placed on a flat surface or mounted in a standard 19-inch rack.
●The maximum ambient temperature ta= 40 °C must never be exceeded.
●The relative humidity must not exceed 50 % with an ambient temperature of 40 °C.
Rack Mounting
The device can be mounted in a standard 19-inch rack. The device requires 1 rack unit (U) of space,
which is 44,5 mm high. Make sure that the rack is sufficiently secured to prevent it from becoming
unstable or falling over.
To mount the device in a two-post rack, follow the steps below:
01) Insert 4 cage nuts in the openings on the rack posts where you want to mount the device.
02) Position the device in front of the rack posts so that the 4 x mounting openings (11) on the flanges
face the openings on the rack posts with cage nuts.
03) Using a screwdriver, mount the device to the rack posts with 4 screws.

5. Setup
Warnings and Precautions
Attention
Connect all data cables before supplying power.
Disconnect power supply before connecting or disconnecting data cables.
Connect the device to power supply only when the amplifiers are switched off, to avoid loud transients
that could damage the connected speakers. See 5.2.3. Connecting to Power Supply on page 14.
Connecting Devices
To connect and use the device, follow the steps below:
01) Install the DSPControl software. See 5.3. Software Installation on pages 15–17.
02) Connect the device to a PC or a Mac, with the supplied USB cable, via the USB-B connector (14).
03) Connect speakers:
●To connect passive speakers, see 5.2.1. Setup with Passive Speakers on page 13.
●To connect active speakers, see 5.2.2. Setup with Active Speakers on page 14.
04) Connect an audio mixer to the 2 x 3-pin XLR balanced connectors IN (15).
05) Switch on the audio mixer.
06) Switch on the device. See 5.2.3. Connecting to Power Supply on page 14 for more information.
07) Switch on the amplifier (if applicable).
08) Switch on the speakers (if applicable).
Note:
After connecting all cables, perform a cabling test.
Attention
Incorrect cabling may damage the speakers.
When performing the test, activate the high-frequency outputs first. If the cabling is incorrect, high-
frequency audio signals will be produced by the bass speakers that cannot get damaged this way.
If you activate the low-frequency outputs first, and the cabling is incorrect, low-frequency audio signals
can seriously damage your high-frequency speakers.
To perform the test, follow the steps below:
01) Press all mute buttons under the output LED indicators (06), to mute all outputs.
02) Activate the outputs.
