Connections overview

The Installation Amplifier’s signal input and output connections are accomplished via RCA Phono and Euroblock style connectors. A GPIO (General Purpose In/Out) Euroblock connector enables some amplifier functions to be controlled, and wireless or RJ45 socket Ethernet network connection options are also provided.
Installation Amplifiers have no mains power switch and are operational as soon as mains power is connected via the IEC 60320 mains socket.
Prior to making any connections to the amplifier we strongly recommend first connecting the amplifier to the network and configuring the amplifier for its intended use, refer to page 6 for network connectivity and page 12 and 18 for output (Lo-Z or Hi-Z)
configuration.
Mains Power Connection
Installation Amplifiers incorporate a power factor corrected power supply and can be used with mains input voltage from 100V AC to 240V AC, 50/60Hz. Use the mains cable supplied with the amplifier and connect it to a switched mains supply.
Lo-Z and Hi-Z
Lo-Z refers to low impedance speaker connections (between 4-8Ohms). This is the default Output mode for our Installation Amplifiers. Hi-Z refers to high impedance speakers (70/100 Volt line).

Connecting to network control

Before making input, output and GPIO connections, it is particularly important that the output amplifier format is configured appropriately for the speakers that are to be connected. To do this, the amplifier will need to be connected to the network. This can be either wired or wireless.
Wireless Connection
A mobile, laptop or desktop device with WiFi functionality and a web browser is required.
Follow the steps below.

1. Connect the Installation Amplifier to mains power using the supplied mains cable and switch it on via the front panel Standby switch. Wait for the front panel WiFi indicator to illuminate orange.
2. Use a mobile, laptop or desktop device to search for available WiFi networks. Connect to, ‘MA [Amp Name] XXXX-XXXXX’ e.g. ‘MA IA750-4 2235-00018’ using the password, ‘password’. The amplifier serial number can be found on its rear panel.
3. Open a web browser and enter the following IP address: 192.168.4.1. The amplifier configuration web interface page will open in the browser app to enable amplifier configuration as required.

It is strongly recommended that the amplifier WiFi password is changed following initial wireless connection. Continue to page 8 to learn about the configuration menus, setup and routing.
Wired Connection
A laptop or desktop device with Ethernet functionality, a web browser and a network scanning app is required. Follow the steps below.

1. Connect the Installation Amplifier Network Control socket directly to a laptop or desktop device – or through a switch.
2. Connect the Installation Amplifier to mains power using the supplied mains cable and switch it on via the front panel Standby switch. Wait for the front panel Network indicator to illuminate orange to indicate that the amplifier has network connectivity.
3. The default LAN IP address of the amplifier is 192.168.64.100. Configure your laptop or desktop device to a fixed IP address in the same IP range, for example 192.168.64.10, with Subnet mask 255.255.255.0 (or prefix 24) and set Gateway to 192.168.64.1.
4. Open a web browser and enter the address http://192.168.64.100/ – The amplifier configuration web page interface will open to enable amplifier configuration as required.

Please refer to page 16 for speaker configuration before connecting your speakers.
The configuration menus are accessed via a web page interface and cover Input, Zone, Output and General Settings functions. The configuration menus are fully described on pages 8-23.

Setup and signal routing

Thanks to their network based configuration features, our Installation Amplifiers offer considerable versatility in terms of sources, signal routing, installation zones and output modes. Inputs can be freely assigned to installation zones, and those zones assigned freely to the available amplifier outputs in either Lo-Z or Hi-Z modes.
This versatility enables, for example, one amplifier simultaneously to drive both Lo-Z and Hi-Z speakers, or for different inputs to be routed to different output zones.
The following  aragraphs  escribe and illustrate the recommended procedure for configuring input, zone and output routing. A general signal flow schematic is also illustrated in the diagram below.

Dashboard
With the Installation Amplifier succesfully connected to a network, searching the IP address from a web browser displays the Installation Amplifiers configuration Dashboard screen, as shown in the image opposite.
From the Dashboard the power can be switched On/ Off and the volume for each zone can be adjusted. If the name for the zone has been altered within the Zone tab the same name will also be displayed here.

Input Setup
Open the configuration Dashboard and select the Input Tab. The Input Tab is shown opposite.

1. To edit default input names simply select and type in the Input Name field.
2. Define a mono or stereo input by selecting the appropriate option. Defining a stereo input will reduce the total number of discrete inputs available.
3. Select an input sensitivity option from the drop-down menu: +14dB, +4dB, -10dB and ‘microphone’ options are available. Generally, the +14dB or +4dB options are appropriate for ‘professional audio’ source hardware with balanced outputs, while the -10dB option is more appropriate for ‘consumer audio’ source hardware with unbalanced outputs. The ‘microphone’ option provides the significantly greater sensitivity required for microphones.

Note: Only dynamic microphones are suitable for connection. Phantom power for condenser microphones is not provided. If necessary, adjust the input gain using the slider, up/down icons or enter the value manually. Gain adjustment is intended for fine output level adjustment following initial use.
Zone Tab
The Zone Tab enables installation zones to be defined and named, and provides access to further submenus. Zones might be bar or restaurant areas for example, or different rooms in a home. For all Zone Tab menus, the installation zone under configuration is selected by highlighting one of the zone identifiers (A, B, C or D) at the top of the page.
Zone Setup & Routing
Open the configuration Dashboard and select the Zone Tab. The Zone Tab is shown opposite.

• Select the zone to be configured from the top of the page. The number of zones available will depend on the amplifier model, input setup and output mode (Lo-Z or Hi-Z). For example, a two output amplifier will have two zones available if only mono inputs configured, but have only one zone available if any stereo input is configured. Similarly, a four output amplifier with only mono inputs configured but one output configured for Hi-Z mode will have only three zones available.

Note: When configured in Hi-Z mode Installation Amplifiers operate in ‘bridged’ mode. This is where the output of two channels is combined for an increase in power. This means that the number of output channels available in Hi-Z mode is half that available in Lo-Z mode. Outputs can also be bridged in Lo-Z mode if using the IA750-2 or IA750-4.

• Name the zone by typing in the Zone Name field.
• Adjust the zone volume if required by using the slider.
• Define a mono or stereo zone by selecting the appropriate option. Defining a stereo zone will reduce the total number of further zones available.
• Specify an input for the zone by selecting from the drop-down menu. Selecting a stereo input for a mono zone will automatically sum the stereo channels to mono. (left -6dB + right -6dB)
• The GPIO Volume Control option enables external volume control to be applied to individual installation zones. The GPIO configuration menu can be found under the Settings Tab.
• The Compressor option enables default or custom signal compression to be applied to individual installation zones.

Note: Compression can be useful to reduce the volume difference between loud and quiet audio material. The lower the compression threshold is set, the more the difference between loud and soft will be reduced. The overall zone volume may need to be increased when compression is used. The default compression parameters are appropriate for most installations.
Output Tab
The Output tab enables amplifier outputs to be named and provides access to further sub-menus. For all Output Tab menus, the amplifier output under configuration is selected by highlighting one of the output identifiers (1, 2, 3 or 4) at the top of the page.
Note: The number of individual outputs available for configuration will depend on the Installation Amplifier model and the input, zone and output mode configuration. For example, the IA60-4 will have four outputs available if Lo-Z mode is selected and two outputs if Hi-Z mode is selected. You can also mix by having two outputs in Lo-Z mode and one output in Hi-Z mode.

Output Setup
Open the configuration Dashboard and select the Output Tab.

• Select the output to be configured.

• Specifying a Zone as stereo will automatically generate three output channel options: left channel, right channel or summed mono. The summed mono signal can potentially be used to drive a subwoofer (left -0dB + right -0dB).

• The Routing menu enables zones to be assigned to amplifier outputs.

• The Delay menu enables audio delay to be applied to individual amplifier outputs.

• The Equalizer menu enables parametric equalization to be applied to individual amplifier outputs. Equalizer settings configured for one amplifier output can be copied and applied to other outputs. The setting can be altered by pressing the Edit function and using the sliders or by clicking on and dragging the different frequency band numbers on the graph itself, as shown in the example opposite. To save any changes press the OK button.

• Select the mode required for the output.

• The Speaker Preset menu allows you to Import or Export presets. For information on creating speaker presets and adding them to your Speaker Library please refer to page 21. Selecting the Speaker Preset tab will also expand the listed options to show the following sub-menus:

• The Crossover & Gain menu enables high or low-pass crossover filters and gain adjustment to be applied to individual amplifier outputs. Crossover filter settings configured for one amplifier output can be copied and applied to other outputs.

• The Speaker EQ menu enables parametric equalization to be applied to individual amplifier outputs following the application of crossover filtering. Equalizer settings configured for one amplifier output can be copied and applied to other outputs.

• The Driver Alignment menu enables delay to be applied to individual amplifier outputs following the application of crossover filtering.

• The Polarity menu enables the polarity of individual amplifier outputs to be reversed.

• The Limiter menu enables signal limiting to be to be applied to individual amplifier output. There is are options for Clip, Peak and RMS Limiting.
  Note: An output limiter can be used to restrict the peak volume level from speakers connected to each output.

• The Output Mode menu enables individual amplifier outputs to be switched off or configured for Lo-Z or Hi-Z modes. In Hi-Z modes, a high-pass filter can also be configured and applied to the output.
  Note: Use of a high-pass filter with Hi-Z loudspeakers is useful to avoid the possibility of distortion caused by low frequency line transformer saturation. Begin with the default filter setting of 70Hz. If low frequency distortion is still audible, increase the frequency setting one step at a time until the distortion is no longer audible.

Settings Tab
The Settings Tab enables miscellaneous amplifier settings to be configured and installation data to be recorded. The Settings Tab provides access to further sub-menus.

• The System Information menu provides text fields for the recording of installation data.
• The Device menu records amplifier specific information such as the model number and firmware version. A firmware update routine and identifier ‘Find Me’ button can also be found under the Device menu.
• The Backup & Restore menu enables amplifier configuration data to be downloaded to an external archive, and enables previously saved configuration files to be uploaded and adopted by the currently connected amplifier. The connected amplifier can also be reset to factory settings from here.
• The Speaker Library menu allows you to create a Library of presets and order them into folders. Refer to page 20 for instructions on creating presets and adding them to your library.
• The Power Management menu enables various automatic switch-on options to be engaged. The Power Management menu also offers timed Standby and Mute functions.
• The GPIO menu enables configuration of the multi-purpose GPIO interface pins, refer to page 22.
• The LAN menu enables configuration and reset of the wired network options and arameters.
• The WiFi menu enables configuration and reset of the wireless network options and parameters.

Presets and Speaker Library
Speaker Presets
Speaker Presets can be made from the parametres and settings within the Speaker Preset sub-menus in the Output tab.
Once you have made your adjustments e.g. Crossover & Gain, Speaker EQ, etc you can export it to a preset to use later.
When exporting presets you can select which settings you wish to export from a checklist and also if you want them to be protected. This will prevent others from making further changes to your preset.
A selection of Presets for Monitor Audio loudspeaker combinations and individual loudspeakers is available from our website: monitoraudio.com
To import presets select Import and then locate the preset file (*.zcp). You can also import presets that have been added to your Speaker Library, which can be generated in the Settings tab. Press ‘Customize Preset’ to modify and enable access to settings. Speaker Library
You can add your speaker presets to a Speaker Library, which can then be exported and imported between Installation Amplifiers. To make a new Speaker Library go to the tab in Settings and select Create, you will then be asked to name the library and set a  ersion number.
Select Speaker Series 1. Using the icons to the right of the window you can Import Speaker Preset(s), Add Series, Edit Series or Delete.
Using the Import Speaker Preset function you can build your library to include all of your speaker presets that you use. Once you have finished press Update to save the changes.

GPIO setup and connection

Our Installation Amplifiers provide a GPIO socket that enables remote control of volume, standby, mute and trigger functions. The GPIO connector pin functions are described in the GPIO Settings menu shown below. The connection of GPIO based remote volume control and standby/mute are illustrated on the right.
Note: The GPIO connector must NOT be used for any unintended purpose. Amplifier damage may result from incorrect use of GPIO.
Note: Shielded cable must be used when connecting standby switches and potentiometers via GPIO.
Note: GPIO Pin 8 has an output impedance of 1kΩ. Connected devices must be able to sink 3.3mA.

Installing

Mounting
Note: The rack mounting and desk/wall mounting components described and illustrated on the right are not supplied with half rack models, but are available to purchase as accessories. Contact your local MA dealer for more information.
Half rack Installation Amplifier models can be configured for rack installation using one standard rack ‘ear’ and one half-rack extension piece as illustrated in the right image. Full rack models will use two standard rack ‘ear’ brackets on both sides. Multiple half rack Installation Amplifiers can also be secured side by side using accessory connecting plates, as shown in the image below.
If not installed in an equipment rack, Installation Amplifiers can be placed freestanding on a flat surface. Adhesive rubber feet are supplied for this purpose. Installation Amplifiers can also be attached to the underside of desks or wall mounted using connecting plate hardware. The adhesive rubber feet should also be used in these circumstances to minimise the possibility of vibration between the amplifier and mounting surface. Wall and desk mounting is illustrated opposite.
Providing sufficient airflow
The installation and equipment rack should be configured to provide appropriate ventilation airflow space around the sides and rear of the amplifier, please refer to the next section below. Ventilation airflow space of at least 25 mm (1”) should be maintained along at least one side of the amplifier at all times. Ventilation apertures are also located on the rear panel of the amplifier and must not be obstructed. It is important to retain at least 80 mm (3”) free space for airflow behind the amplifier rear panel.

Operation

Once all connections have been made and configuration options selected, the Installation Amplifier(s) are ready for use. If an input signal above -60dB is present on any input, the front panel Input and Standby indicators will illuminate orange to indicate normal amplifier operation. Audio will be heard from any connected speakers.
Note: Installation Amplifiers will not switch on from Standby Mode unless an analogue input signal is present or a network or external standby switch is operated.
Amplifier outputs will mute if no input signal is present for 5 minutes, and the amplifier will switch automatically to Standby Mode if no signal is present on any input for more than 15 minutes. Alternative standby and mute delay times can selected via the  Settings Menu. Amplifier cooling fan speed is temperature controlled. The fan will switch off when the amplifier enters standby mode.
