1.2 AUDIO PLAYBACK SYSTEM

The following figure shows the main elements involved in the audio playback system

through AudioInRoom, either from an external Bluetooth source or from the Auxiliary

Input:

Figure 1. AudioInRoom playback system elements.

AudioInRoom: KNX system for audio playback from a device connected via

Bluetooth or through the auxiliary input. Enables Play/Stop, Next

track/Previous track and volume control through KNX bus.

Bluetooth Streaming: Bluetooth audio source linked to the KNX device by

means of a pairing with configurable password.

Auxiliary Input: AudioInRoom can also be connected to systems without

Bluetooth. This is possible thanks to the Auxiliary Input, using an analogue

audio connector (mini Jack) or a RCA connector. In these cases, the

playback control can only be carried out from the own user device audio

player.

signal from each channel can be configured to be played in stereo or mono

mode.

1.3 INSTALLATION

AudioInRoom is connected to the KNX bus through the built-in terminal (2). This device

requires an external 24V DC power supply (1).

Figure 2. AudioInRoom.

A short press in Programming Button (4) will make the device enter the programming

mode. The Programming LED (3) will then light in red. On the contrary, if this button is

held while the device gets connected to the bus, AudioInRoom will enter the safe

mode. In such case, the programming LED will blink in red colour.

Moreover, a 3 seconds press in Testing Button (8) turns the Bluetooth module on and

sets the device into pairing mode. The Testing LED (9) will light:

In blue when the Bluetooth module is on.

In green when pairing is active.

Flashes red in the absence of KNX bus voltage, blending with the other

colours if several notifications are made at the same time.

If a device without a Bluetooth module is to be connected, it must be connected via the

audio auxiliary input (6). Figure 3 shows the correct AudioInRoom auxiliary input

connection, depending on whether a Jack analogue audio connector or an RCA

connector is used:

2. KNX Connector.

Figure 3. Auxiliary Input: Jack connector (left) and RCA connector (right).

Once the AudioInRoom is connected to an audio source, the processed audio output

will take place through the audio output channels (10). Two independent channels

with two connectors each for the speakers are available.

The following figure shows how to connect the audio output channels:

instructions or about the installation process, please refer to the corresponding

Datasheet, bundled with the original package of the device and also available at

1.4 BLUETOOTH CONNECTION

AudioInRoom connection with an audio source device through the Bluetooth module is

a simple procedure that maintains connection security at all times when carried out

using a configurable password.

1.4.1 CHECK-IN / CHECK-OUT

The' Check-in' process represents the arrival of a new user to the room and establishes

a new identifier name for the AudioInRoom and a new password or PIN to link to it.

These two values are set by communication object.

Instead, the Check-out process resets the name and password to the default

(parameter) settings. In addition, the list of devices linked to AudioInRoom is deleted,

so that any user who wants to reconnect to AudioInRoom must repeat the pairing

process.

The Check-in or Check-out processes will not be interrupted by the arrival of new

Check-in or Check-out orders. Once finished, the last order received is analysed and, if

it is the opposite than the process just finished, the pertinent actions will be executed.

1.4.2 PAIRING

The pairing process is initiated in AudioInRoom by sending the order via the

corresponding communication object or by pressing (more than three seconds) the test

button.

Once the pairing mode is activated, the AudioInRoom will remain visible via Bluetooth

for approximately 3 minutes . It can be identified by the name established in the

Check-In process or by the name established by parameter in ETS.

When selecting the desired AudioInRoom to connect to, the pairing PIN is requested.

This PIN, again, may be the one established in the Check-in process or the one

established by parameter in ETS.

For serial numbers prior to 20ACC0494 the time it will remain visible will be 1

minute.

AudioInRoom

https://www.zennio.com Technical Support: https://support.zennio.com

After entering the PIN, the audio source device and AudioInRoom will be paired and

connected:

Connected Device: the device has already been paired through the security

PIN and it is connected to AudioInRoom. At this point the sound from the

device will be heard through the speakers connected to the AudioInRoom

audio output channels. In addition, playback and volume controls can be used

from the AudioInRoom

Paired Device: the device has already been paired through the security PIN.

However, the audio-multimedia connection has been disabled. AudioInRoom

does not allow the user to play music in this state.

AudioInRoom enables to have up to two devices paired and connected, so that audio

can be played from any of them, although, logically, not at the same time. When the

device playing the audio changes, the volume of the AudioInRoom is reset to the initial

value set by parameter.

If a third device is paired, one of the two previous devices will be deleted, which means

that it will have to be paired again if it wants to reconnect.

Note: If a pairing process starts while a Bluetooth device is playing music, and it is not

successful (cancellation, incorrect PIN or time exceeded), the playback will pause.
