Introduction

Professional soundbar

**** The IMEO2 Soundbar features a slim and elegant design and includes all required functions for the expansion of any audiovisual system with an impressive sound while having a minimal hassle for installation. It’s perfectly suited for installations such as classrooms, presentation rooms, or meeting rooms where it can be used and installed in combination with screens, smartboards, or projectors.

The acoustics originate from a 3-way speaker construction, composed of two 1.5” high-frequency drivers, two 2” mid-frequency drivers, and a low-frequency section with two 2.5” low-frequency drivers with an RMS rating. The power handling reaches an overall level of 60 Watt RMS. The Class-D amplifier with integrated WaveSelect DSP processing and transmission line configuration for the low-frequency drivers offers a crystal clear sound reproduction with a stunning low-frequency response. Selectable DSP presets offer optimization for applications such as presentations, music playback, or videos.

Various input possibilities such as an unbalanced line input, HDMI (ARC) input, or SPDIF (optical and coaxial) allow compatibility with a variety of input sources, while Bluetooth allows wireless connections with portable devices. In installations with multiple IMEO’s installed throughout the area, it can be desirable to assign custom Bluetooth IDs to distinguish them from each other. Typical applications are hotels, conference rooms, schools, … The hotel mode function in the firmware offers a solution for these applications. An additional function is also implemented to define a specific wake-up source, allowing the IMEO2 to always turn on with the same input source selected, no matter which input source was selected before power-down.

An included IR remote control allows input selection, volume control, and EQ preset selection while the unique and clever wall mounting bracket allows convenient mounting to walls on any kind of surface or location with optimal guiding and coverage for the cables.

The auto standby function ensures that the IMEO is automatically put in energy-saving mode after 15 minutes without input. This way, no unnecessary energy is lost, while the IMEO remains ready to play at any moment.

All the lights will be on during the update process. When the update is completed the IMEO2 will automatically enter standby mode. The IMEO2 is now updated.

DISABLE / ENABLE SPECIFIC FUNCTIONS

In projects with public system access such as classrooms or conference rooms, it can be desirable to lock it in a specific operation (input) mode or disable specific functions, to avoid users changing the input signal.

Lock input:

To lock the soundbar in a specific input function (disable the operation mode selection), turn the unit ON and switch to the desired audio source (e.g. AUX input). Press and hold the ‘AUX’ button (or other selected function) on the remote control for about 5 seconds to enable the lock. All status indicator LEDs will blink now simultaneous and the input selection will be locked. (the input can’t be changed by the user). Press and hold the selected function button again for about 5 seconds to disable the lock. All status indicator LEDs will blink again simultaneously and the lock will be disabled.

Disable Bluetooth:

To disable the Bluetooth function, make sure the unit is in standby mode and press and hold the BT button on the remote control for about 5 seconds. The blue Bluetooth indicator LED will blink and the Bluetooth function will be disabled.
Press and hold the BT button again for about 5 seconds in standby mode to enable the Bluetooth function again. The blue Bluetooth indicator LED will blink and the Bluetooth function will be enabled again.

Disable auto-standby:

To disable the auto standby function, make sure the unit is in standby mode and press and hold the power button on the remote control for about 5 seconds. The green indicator LED will flash 3 times and the auto standby function will be disabled.
To enable the auto standby function, make sure the unit is in standby mode and press and hold the power button on the remote control for about 5 seconds. The red indicator LED will flash 3 times and the auto standby function will be disabled.

Disable volume control on the main unit:

To disable the volume control on the main unit, make sure the unit is in standby mode and press and hold ”VOL+” and “VOL-” buttons on the main unit. The blue indicator LED will flash 2 times and the volume control will be disabled.
To enable the volume control on the main unit, make sure the unit is in standby mode and press and hold ”VOL+” and “VOL-” buttons on the main unit. The blue indicator LED will flash 4 times and the volume control will be enabled..

HOTEL MODE

In installations with multiple IMEO2’s installed throughout the building, it can be desirable to assign custom Bluetooth IDs to distinguish them from each other. Typical applications are hotels, conference rooms, schools, … The hotel mode function in the firmware offers a solution for these applications.
Using the hotel mode, the Bluetooth ID can be adjusted to ‘AUDAC – IMEO2 + xxxx’ where ‘XXXX’ is a 4-digit number, representing the room number, class number, meeting room number, …
Additionally, a function is implemented to define a specific wake-up source, allowing the IMEO2 to always turn on with the same input source selected, no matter which input source was selected before power-down. To enable hotel mode, follow the below steps:

Disable auto-standby:

• Switch IMEO2 to standby mode (upper RED LED illuminated)
• Press code ‘6280’ on the remote control to enable hotel (see the image as below) (6280 = COAXIAL – BT – PAIR – VOL-)
• The Green LED will start to blink (others are continuously illuminated)
• Enter the first number of the 4-digit ID (see the image below)
• The Blue LED will start to blink (others are continuously illuminated)
• Enter the second number of the 4-digit ID (see the image below)
• Repeat for numbers 3 and 4

After the 4 digits of the Bluetooth ID are entered, the upper (standby) LED will start to blink.

Now the wake-up input source can be selected with the last digit:

• 1: AUX
• 3: HDMI ARC
• 0: No specific wake up source

The BT name will now be changed to e.g. ‘AUDAC IMEO2 – 1234’ (in case 1234 was entered) To exit the hotel mode function, press code ‘0826’ on remote control to enable hotel mode.
