Introduction
The Meridian 271 Digital Theatre Controller allows you to integrate Meridian DSP loudspeakers with a variety of AV systems to create a digital or analogue theatre that takes advantage of Meridian's authentic, natural sound.
Designed to work with any processor on the market, the 271 is a High Resolution interface that allows you to design and build high performance theatre systems with 20 or more channels.
The 271 is rack-mountable and can be stacked to give 40 or even 60 audio output channels, all with Meridian's (MHR) High Resolution Audio output and a simple IP control interface.
Audio inputs
The 271 supports 16 channels of analogue audio on either single-ended or balanced input connections (RCA or 2 x 8 channel DB25 connectors).
It also provides balanced digital input options available to support 16 channels of digital audio fed from Trinnov, Datasat and Storm Audio processors (2 x RJ45 and 1 x DB25).
The 271 includes a SpeakerLink input for connecting a Meridian source to the main left and right loudspeakers.
Audio outputs
The 271 provides 16 + 4 digital audio outputs on SpeakerLink connections for use with Meridian DSP loudspeakers using high precision 96kHz/24-bit analogue to digital conversion.
The digital outputs support Meridian High Resolution (MHR) encoding which improves audio quality compared to a standard digital audio stream by improving jitter characteristics within the associated electronic circuitry.
The 271 also provides 16 + 4 analogue audio outputs on unbalanced RCA connectors to allow the use of passive loudspeakers.
Inputs 1 to 16 are mapped in parallel to both sets of 16 outputs, analogue and digital, providing support for mixed systems using combinations of analogue and Meridian DSP loudspeakers.
The two sets of four additional outputs (four digital and four analogue) can be independently configured to duplicate any of the 16 input channels to provide feeds for a wide range of combinations of loudspeakers and subwoofers.
2 Meridian 271 Digital Theatre Controller User Guide
System integration
The 271 Digital Theatre Controller is designed to be both configured and controlled via its Ethernet socket.
The 271 can be configured simply by entering the product's IP address into a standard web browser; this then gives access to the range of setup and operational options.
Trigger input and output connections allow coordinated switching of components within systems using a mix of speaker types, such as enabling a power amplifier.
The 271 supports Meridian Comms so it can be controlled from a DSP loudspeaker using a MSR+ remote or a product connected to the SpeakerLink input of the 271.
Ethernet control
The 271 can also be controlled via the Ethernet connection using the Automation Protocol, which allows full control of all runtime settings of the unit including source selection, volume, and audio menus.
Installers can integrate the Automation Protocol into an automation system; for details contact Meridian support.
The Automation Protocol can also be accessed directly via a tablet or smartphone running the Meridian IP Control app; see Controlling the 271 Zone Controller, page 18. This is a free
application for iOS devices; search for Meridian in the Apple App Store to download it.
Paralleling 271 Digital Theatre Controllers
In theatre systems with more than 16 channels of audio to distribute, multiple 271 Digital Theatre Controllers can be used in parallel to provide coordinated operation for the whole speaker array. We recommend contacting Meridian Support for the relevant technical information.
Accessories
The following accessories are available for the 271:
- A Meridian G12 remote eye to receive infra red signals.

Meridian 271 Digital Theatre Controller User Guide
This is a 7.1 system based on a 271 in conjunction with an AVR system with balanced analogue outputs. It uses Meridian DSP loudspeakers for the front channels and the subwoofer, and passive loudspeakers for the side and rear channels; these are powered by four channels of a Meridian 258 Eight Channel Amplifier.
In addition, this system uses a Meridian 218 to provide two-channel analogue and digital inputs. The 218 can also be connected via Ethernet to a Meridian Sooloos system, allowing access to music in the theatre.
- Connect the balanced analogue outputs from the Analogue AVR system to the balanced analogue inputs on the 271, using a balanced XLR to DB25 cable.
Even though all audio paths through the 271 are equivalent, we recommend that the main left and right signals are connected on XLR inputs 1 and 2. This is because the SpeakerLink input will always be routed to outputs 1 and 2, which should be the main left and right loudspeakers.
- Connect four Meridian DSP loudspeakers to the main (1 and 2), centre (3), and subwoofer (4) SpeakerLink outputs on the 271.
- Connect analogue outputs 5, 6, 7, and 8 from the 271 to the inputs of four channels on the Meridian 258 Eight Channel Amplifier.
- Connect the outputs from the corresponding channels on the 258 to the side and rear passive loudspeakers.
A suggested configuration is:
- Front left and right: 3 x Meridian DSP5200.
• Front centre: Meridian DSP5200HC.
- Subwoofer: Meridian DSW.
- Sides and rears: passive loudspeakers.
In this mixed system the AVR should be used to change the bass and treble, since the 271 will not affect these settings on the analogue outputs. The 271 should be used for volume adjustments and specific DSP loudspeaker features such as Centre Elevation.
If you are using an Ethernet-based automation system, for best results connect it to the Network socket on the 271 (rather than the 218).
Configuring the 271 Digital Theatre Controller
The 271 contains a built-in web interface, allowing it to be configured via the Ethernet connection using a standard web browser.
Displaying the 271 configuration page

Discovering the IP address of the 271
To discover the IP address of the 271 you can use any of the following methods:
- The IP Control app (see IP Control app, page 18) will automatically discover the 271 and link directly to the 271 configuration page.
- On a Touch:PC it can be found using the Device Manager.
- Log in to the network router and view the list of attached devices.
- Use a network IP scanner to 'ping' a list of addresses on the network.
Meridian 271 Digital Theatre Controller User Guide
Identification
Identifies the product software version, network MAC address, and Zone Name.
Zone name: This identifies the product in the appropriate control interface such as Touch:PC, Control:15, and Control:PC. It is initially set to a unique string, but would normally be set to a meaningful label such as Kitchen or Study.
Source configuration
Allows you to configure the 12 Meridian sources.
Legend: A string of up to 5 characters which will be displayed on the Automation interface, and on DSP loudspeakers.
12 Meridian 271 Digital Theatre Controller User Guide
Audio input: Each of the 12 logical sources can be assigned to any of the audio inputs: Analogue-RCA, Analogue-DB25, Digital-RJ45, Digital-DB25, or SpeakerLink.
Alternatively any source can be set to Last Valid, which changes the other settings but leaves the input unchanged, or Off, which makes the source unavailable.
Trigger: Can be set to On, Off, or LV (Last Valid) to control the trigger output. Note that the trigger is always off in standby.
Validity: Some sources, such as the Meridian CD players, use the Validity flag in the S/PDIF audio stream to indicate that the audio should not be played. Setting this may reduce unwanted noises in some situations.
Comms Type: For Comms-connected systems, ensures that the appropriate set of commands is sent to the product. The following categories are available:
1C = CD player, 2C = Radio, 3C = DVD player, 4C = Sooloos All others should be set to NC (No Comms).
Address: If there are two or more products of each type then the address should be 1A for the first, 2A for the second, etc.
Startup
Startup volume: Specifies the initial volume for the outputs. The start volume is set when the 271 is first powered up, and a few seconds after going into standby.
By default the 271, and the DSP loudspeakers, start at volume 65 and retain the last volume setting when they enter or leave standby.
Startup source: Specifies the source that the 271 will start with if the user has a Source key on their chosen user interface. This will also be the source that is selected when the user presses the front panel button.
State after power up: Specifies whether the 271 should start in Standby or On when powered up.
Channel duplication
Allows you to specify which pair of channels 1/2 to 15/16 are duplicated to the analogue outputs A/B and C/D, and the digital outputs A/B and C/D.
For the analogue channels you can also specify that the output pair should be: left and right (ie as they were input), both left, or both right, allowing multiple duplication of individual channels.
To achieve the same multiple duplications of digital outputs, configure individual DSP loudspeakers as left or right in order to select which of the pair to play back.
Audio menus
The options on the Audio menus page allow you to specify the default values of settings on DSP loudspeakers when the 271 is powered up, and change the settings when the loudspeakers are being used.
Enable SpeakerLink: Specifies whether the SpeakerLink output is on or off.
Meridian 271 Digital Theatre Controller User Guide
Treble, Bass, and Axis
These settings can be controlled either by SpeakerLink or by Meridian Comms. The default values can only be set via SpeakerLink. To use these controls via SpeakerLink the
Enable SpeakerLink option should be set to On.
These settings do not affect the analogue outputs, so in a mixed analogue/digital theatre you should use the adjustments available on the AVR.
Treble: Tilts the frequency of the response over the entire frequency range to make the sound brighter or dimmer. It can be adjusted between ±10 db in 0.5dB steps.
Bass: Adjusts the bass response in the room by ±5dB in 0.5dB steps.
Axis: Allows you to adjust the optimum listening height of the loudspeakers, like a balance control operating in the vertical plane.
SpeakerLink controls
These controls only affect DSP loudspeakers connected via SpeakerLink. To use them the Enable SpeakerLink option should be set to On.
The effect of these options depends on the capabilities of the DSP loudspeakers in the system; see the individual loudspeaker user guide for more information.
Enhanced Bass Alignment: improves the bass alignment in DSP loudspeakers that support it. Note that the extra processing adds a time delay, so it may need to be disabled for video sources.
Loudness: Alters the loudspeaker response for listening at low volume levels.
Centre elevation: Can be set to Max, Med, or Min to raise the image projected by the centre speaker. This creates a much more involving movie experience, with superior image integration across the whole width of the audio presentation.
Subwoofer gain: Allows you to adjust the gain of the subwoofer(s) by from -15dB to +15dB.
Subwoofer filter: Adjusts the subwoofer crossover frequency. The options are Wide (subwoofer plays the full range of audio frequencies), Sub2 (120Hz crossover), Sub1 (80Hz crossover), or Off (subwoofer off).
Enhanced Boundary Control: Compensates for reflective room surfaces. Choose between Off (unreflective), Min, Med, or Max (highly reflective).
Room height: Used for Enhanced Boundary Control calculations in loudspeakers with downward-firing drive units, such as the M6 or DSW, to compensate for reflections with the room ceiling. Can be varied between 150cm (58in) and 400cm (158in) in steps of 5cm (2in). If the room height is outside this
Meridian 271 Digital Theatre Controller User Guide
range set the nearest available value.
Measurement units: Changes the units used for specifying the room height: Inches for inches, or Metric for cm.
Comms
Master speaker: Specifies which pair of loudspeakers are the Master speakers. These should be Meridian DSP loudspeakers.
System Address: If an installation contains multiple zones that are connected together with Meridian Comms, each one needs a different System Address if they are to have
independent source selection and volume controls. If the installation uses LAN connections then this can be left at its default, 1A.
Product Address: If there are two or more Meridian sources in the same category on the same Comms-connected system then each unit must have a different Product Address. The setting does not apply to IP connected systems and should be left at its default, 1A.
IR mode: The IR mode is only relevant if a G12 has been connected to the 271. In this setup the installer should set the mode to Controller to ensure that the unit functions as the system controller.
IR receiver is currently: Shows the state of the IR receiver.
Meridian 271 Digital Theatre Controller User Guide
Ethernet
Allows you to change the Ethernet configuration. Note that incorrect settings may make the 271 unreachable via the web page.
Restore Settings
Allows you to restore one or more groups of settings to their factory defaults. Note that restoring the Ethernet settings will enable DHCP, which may change the IP address of the 271, and you may have to find the new address as described below.
- Select the checkboxes corresponding to the settings you want to restore.
- Click Reset Selected at the bottom of the page.
Zone name: This is used by the Automation Interface to identify the unit. The factory default uses a combination of the product name and MAC address.
Meridian 271 Digital Theatre Controller User Guide
Audio output: Returns the A/B & C/D channel duplications to their defaults.
Audio menus: Resets the settings on the Audio menus page.
Source configuration: Restores the source legends, their associated audio inputs and Comms configurations; see Sources, page 11.
Comms and startup choices: Returns the startup state to standby and volume to last valid.
Ethernet configuration: Removes any static IP selection and re-enables DHCP. If this box is ticked then the unit will begin the process of getting a new IP address automatically. It may be given a new address by the DHCP server, in which case you will have to find the new address; see Discovering the IP address of the 271, page 10.
Controlling the 271 Digital Theatre Controller
The Meridian 271 can be controlled using the following options:
• Via Meridian Comms from another product such as a Meridian CD Player.
• Via the Ethernet connection using the Automation Interface.
- Via Infra Red, using the optional G12 remote IR sensor and either the MSR, MSR+, or AC200 remote controls.
IP Control app
Meridian provide a free app for iOS called IP Control that uses the Automation Interface of the 271. Search for Meridian in the Apple App Store to download it.
Ethernet connection
A LAN connection is required to configure the 271 Powered Zone Controller. Also, various aspects of the update and support systems require that the LAN allows Link Local addressing and multicast transmission as well as UDP and TCP traffic. Simple unmanaged switches will always pass this traffic but Wireless Access Points should be selected carefully and managed switches must be configured correctly to pass this traffic.
Third-party IR inputs
The Meridian G12 IR sensor has the following pinout:
Third-party IR receivers with the same pinout may be compatible but their operation is not guaranteed.
Many home automation/control systems feature outputs suitable for feeding IR emitter devices (also referred to as "IR blasters"). These signals differ from those derived from infra-red receivers in that they are modulated with a carrier frequency. The 271 will automatically detect this and extract the underlying IR signal. Use only the Ring and Sleeve connections for these devices; the Tip (12V) should be left unconnected.
For details of the Automation Interface and the IR control codes see the Meridian website:
www.meridian-audio.com
Meridian 271 Digital Theatre Controller User Guide
Trigger input and output
The trigger input and output are both designed to use mono 3.5mm jack plugs. The input circuitry is optically coupled, so works for either polarity of signal across tip and ring. The output presents a +12V signal on tip and ground on ring:
Trigger input
By default the 271 will respond to rising or falling edges on the trigger to mean on and off respectively. The product will leave and enter standby in the same manner as if the front panel button has been pressed.
Trigger output
Each logical source has a configurable trigger setting, when that source is selected the trigger level will either:
- Turn on
- Remain at the current level (Last Valid)
- Turn off
The trigger will always go off when the product is in standby.
