Page 12: Connecting The Iris
CON700 - I/O connector; Description 16-pin 1.27 pitch This pin is used for the GND of the Digital Input/Output. On the bottom side we find: CON103 U.FL antenna connector. Connecting the Iris Connecting the power Plug the power cord in the the mains outlet. In the process we ask that you play careful attention to the following instructions: Always ensure your hands are dry before plugging in or unplugging the power cord from the mains.
Page 13: General Installation Notes
Do not cut or damage the power cord and do not place heavy objects on the cord. This can cause short-circuit, resulting in electrical shocks or even fire. Pulling on the power cord can damage the wire or insulation, potentially causing electrical shocks or fire.
Page 14: Interfacing To The Amp-Device
Optionally in the Iris DSP Amplifier Module, the mains power supply can be replaced by a rechargeable battery. Please note this option is not available yet from Streamit. In this case a battery interface pcb needs to be connected to CON602 and the jumper on CON601 needs to be removed.
Page 15 A great feature is the digital output for switching an external power source through a relay. This option is available through a Phoenix connector on the Iris Brick and the I/O connector on the Iris Brick. Antenna input/output The mono or stereo audio signal is received through the wireless interface. In the Configuration chapter is described how you configure the antennas.
Page 16: Building Your Own Wireless Loudspeaker
Building your own wireless loudspeaker The Iris Brick and Iris DSP Amplifier Module (AMP-devices), but also the Iris Receiver can all be integrated with your loudspeakers. · The Iris Receiver is ideal for loudspeakers with an integrated amplifier. · The AMP-devices are ideal for loudspeakers without integrated amplifiers. The AMP-device features a two-channel amplifier with integrated DSP, allowing you to create the crossover electronically for significantly improved audio performance.
Page 17: Configuration
Configuration The configuration of your Iris audio networks will be done using the Iris configurator, a companion mobile app for Android and iOS. The mobile app is currently under development and not yet available to the user. For as long as the mobile app is not available, the Iris Service Tool should be used.
Page 18 · Start the Iris Service Tool and make sure both TX-device and RX-device are connected. · Select the TX-device and make sure the transmitter configuration (the DECT region in particular) is correct. Unless you have a good reason to use a fixed antenna setting, the (default) diversity mode is likely the best option.The audio mode setting should align with your application's requirements.
Page 19: Relay Control Functionality
Relay control functionality The Iris has been designed to facilitate switching of equipment such as amplifiers or active speakers whenever audio is not required. With the relay control functionality, digital input pin changes on the transmitter are transparently communicated to the digital output pins of all receivers in the audio network. This is default behavior and requires no configuration.
Page 20: Led Status Information
LED status information The Iris Brick amplifier features two status LEDs. A LED can be switched off or light up: solid, slow blink ( ), fast blink( LED: Status Paired to a TX-device and listening to the broacast (audio channel is active) Contains pairing information, but TX-device is not reachable (not listening to broadcast) Locked to a TX-device, but audio channel inactive (should not happen) Not paired to a TX-device...

Page 25: Protective Measures
Protective measures The audio amplifier of the AMP-device contains a range of protection features to avoid damage to the amplifier itself or the attached speakers. The integrated protection system monitors a range of parameters to check if min/max thresholds are exceeded.
Page 26: The Iris Service Tool
The Iris Service Tool The Iris Service Tool is a Windows PC app initially designed for service purposes. The tool has been updated to allow users to configure and monitor their Iris audio networks, until the mobile app (Iris configurator) becomes available. The Iris Service Tool communicates with Iris devices over USB.
Page 27: Dsp Configuration
Using the Iris Service Tool you can upload up to 6 DSP presets to your AMP-device, and select which preset to activate. · Download and install the “MERUS Audio Amplifier Configurator” (https://streamit.eu/dl- content/temp/tools/merusaudioamplifierconfigurator_2.0.1.202402281050.zip) · Start the tool and disregard the 'Disconnected' in the status bar, as the MERUS configurator does not connect directly to the Iris.
Page 28 · Select the DSP tab, then access the and select the flow that best fits your needs, from the 48kHz section. It us also possible to open an already existing flow you might have saved earlier. · Configure the DSP to your needs, eventually saving the DSP flow for later use (Save as/Save buttons at the bottom).
Page 29 · From the main application screen we can export the DSP configuration we just created/updated, so it can be used as a preset for your Iris AMP-device. Open the configuration menu using and select the option "Export Configuration" User Manual: Iris Amp series...
Page 30 · Select a folder for the configuration to be saved, eventually creating a new one when needed. · On confirmation of the folder to save your output to, the DSP configuration gets exported in different formats with different files being generated.

Page 32: Troubleshooting
Resetting a device will apply factory default values for all settings and can be executed using the Iris configurator. This action requires using the factory reset PIN which is intentionally not documented. For help, please contact Streamit support. Receiver devices running firmware 1.6 or newer can also be reset using the relay control input. This will require making a simple reset dongle using a terminal block connector, and connecting a wire between input and ground.
Page 33 When you reset a device the pairing information will be lost, which in the case of a transmitter means the complete network. User Manual: Iris Amp series...
