CABLING/WIRING AND SETUP
Before putting the device into operation, make sure to observe the technical specifications for all compo-
nents, such as the maximum output level of auxiliary devices, the maximum input level of the loudspeaker
switching system, and connected powered loudspeakers or power amplifiers! In case of uncertainty, con-
sult an experienced audio technician. Use high-quality and, if possible, balanced cables for cabling/wiring.
In the following, you will find information about how to cable/wire and set up the loudspeaker switching
system with powered loudspeakers. This procedure can also be used for cabling/wiring and setting up a
power amplifier and unpowered loudspeakers.
• Before you start cabling/wiring, turn off any devices to be connected to the loudspeaker switching sys-
tem and set the volume of all devices to minimum.
• After the cabling/wiring is completed, turn on the connected loudspeakers and power amplifiers as the
last devices.
• Adjust and match the volume of the connected loudspeakers to each other to prevent sudden spikes in
volume when switching the speaker outputs.

device’s audio signal, first switch off all OUTPUT LOUDSPEAKER and SUBWOOFER outputs (see Point 13). If
there is a signal and the LED does not illuminate, the input level is not being clipped, if the LED illuminates
red briefly, or if it illuminates red permanently, the auxiliary device’s output level must either be reduced or
the input gain must be set to a lower value using the web-based app.
OUTPUT LOUDSPEAKER and SUBWOOFER line outputs: If a signal is fed into one or more line outputs, the LED
illuminates green; if an output is being clipped by an excessively high signal level, the LED illuminates red.
Reduce the corresponding line output’s output level as described in Point 13 or use the web-based app to
adjust the setting.
APP CONTROL
In principle, it’s possible to establish a connection to the Grand Audition MK2 with any Ethernet- or
WLAN-capable terminal device. The operating system used is of secondary importance since the Grand
Audition MK2 is controlled using a browser. Windows, Apple, and Linux operating systems, and tablets
running on iOS and Android are suitable. Chrome, Safari, and Firefox browsers are recommended. Your
computer or tablet should have a min. screen resolution of 1024 × 768 pixels; use the display in landscape
format. Smartphones are not suitable for controlling the app due to the small display size.

SOURCE: Selection of the signal source for the master device and setting of the input gain.
XLR: Balanced 3-pin XLR inputs L and R on the front and back of the device (INPUT L + R).
PLAYER: Audio player with USB type-A connection socket on the back of the device.
XLR GAIN: Setting the input gain for the XLR inputs to match the connected auxiliary device (mixer, CD
player, etc.). The values 0 dB or -6 dB are suitable for auxiliary devices with a high output level. A higher

5LINKED GRAND AUDITIONS
Up to three Grand Audition MK2 devices can be cascaded together and controlled with the brows-
er-based app. The settings for the first slave unit (First Slave) are made under FIRST SLAVE IP ADDRESS (IP
address of the first slave unit) and TOP CHANNELS (STEREO/MONO). The settings for the second slave unit
(Second Slave) are made under SECOND SLAVE IP ADDRESS (IP address of the second slave unit) and TOP
CHANNELS (STEREO/MONO).
CHANNELS
Click the CHANNELS tab to open the window for activating and deactivating channels. The factory default
is that the group with the mono or stereo channels uses numbers (CH 1 to CH 16 or CH 1/2 to CH 15/16),
and the second group with the mono channels uses letters (CH A to CH H). The channels, however, can be
individually labelled (see VOLUMES tabs). A dividing line visually separates the channel groups. If necessary,
scroll up or down to view the desired channels. Click the corresponding button to activate or deactivate
the desired channel. An activated channel’s button is highlighted in orange.
