Page 12: Installation Instructions
INSTALLATION INSTRUCTIONS Mechanical Installation The Di Series Amplifiers are designed to be mounted in a standard 19” rack enclosure. Where the amplifier is used in a fixed installation, as long as the bottom unit is supported and there are no gaps between units, it is acceptable to use only the front panel 19” rack holes when fitting it in a standard rack enclosure. -
Page 13: Ac Power Connection
To prevent damage to the front panel it is recommended that plastic cups or washers are fitted underneath the rack mounting bolt heads. It is possible to mount multiple Di Series amplifiers without ventilation gaps between them but it is essential that an unobstructed flow of clean air is available from the front of the unit to the rear. -
Page 14: Introduction And Key Features
Introduction and Key Features Introduction The EM Acoustics Di Series Advanced Installation Amplifier represents current state-of-the-art technology in several areas. This product is the result of several years of research, from which many advances in switched mode power technologies and ever finer detail in signal processing have stemmed. - Page 15 Drive Modules The Di Series processor has a new way of ordering and grouping channels in order to give a more speaker-based approach to controlling, designing and recalling speaker configurations; these are called Drive Modules. A Drive Module is the Processing provided by one Input DSP Block, and a number of Output DSP Blocks, which are associated with one-another by means of routing.
- Page 16 FIR Linear Phase Equalisation The Input High-Shelf Equalisers use Finite Impulse Response (FIR) filtering to produce Linear Phase equalisation; that is all frequencies are delayed by the same amount, perfectly preserving the transient response. This can also be important in applications where different amounts of EQ are applied to different parts of a speaker cluster, such as to add 'Throw' EQ boost so that parts of cluster which are throwing further can have HF absorption correction added.

Page 17: Audio Connections
Audio Connections Input Connections For each input channel there are 3 pins of a Phoenix connector for analogue inputs. There is also a 6 pin Phoenix connector for one stream (two channels) of AES3 digital audio. The three terminals marked ‘In’ should be used as the AES3 input to the device. The ‘Link’ terminals are intended to feed a buffered version of the input on to another device. -
Page 18: Amplifier Output Connections
Amplifier Output Connections On the Di Series amplifiers, all outputs are Bi-Amp; each Speakon connector carries two amplifier outputs – Channels 1&2, Channels 3&4, Channels 5&6 and Channels 7&8. Amplifier output connections – 88C and Bi Amp Speaker1 - Speaker1 + Speaker2 - Speaker2 + In addition, all the Speakon... -
Page 19: Panel Layouts
Panel Layouts Power Switch- Applies mains power to the device. If the device has entered Sleep mode, it may be woken up again either from the System Engineer application, or by switching this switch off, then on again. Status Indicators- The “OVERLAY” indicator shows when there are parameters active on a group layer, which the user cannot access through the front panel of the device (see ). - Page 20 Relay A output: This isolated relay output may be used to indicate abnormal conditions to external monitoring apparatus. The default operation is to indicate a Fault Incident. See Fault Relay Power Inlet: The unit should be connected to a suitable mains electricity supply using an earthed Powercon connection power lead.

Page 21: Operation
Operation Starting up the unit When power switch is switched on the unit will go through its start-up cycle, checking all the sub- systems as it does so. Along the way, the indicators will inform you of its progress by lighting more indicators while the indicated progress ‘wheel’... -
Page 22: Drive Module Presets
These concepts are depicted in the System Engineer application as in the following example of a 2- way Module: Snapshot is a device-wide representation of most of the settings in the device. This is represented as eight Input Component numbers, or eight Output Component numbers, plus a number of machine- centric settings such as routing and Input/Output Analogue/Digital selection etc. -
Page 23: Factory Module Presets
Factory Module Presets Factory Presets Di Series amplifiers contain a library of designed to suit the EM Acoustics range. Factory Presets contain some parameters that are fixed and hidden from view; these are those parameters that are critical for the correct operation of the loudspeaker, such as high/low pass filters Factory Presets and limiters. -
Page 24: Networked Audio (Dante) Inputs
Networked Audio (Dante) Inputs When the Digital Audio Network option is fitted, it is possible to select any channel(s) as being sourced from this network. To do this, connect the audio network connection to the connection on the rear of the Device, and set the relevant Input Type parameter to “Dante” (for example.) When the Digital Audio Network input is installed and routed, the “Net Audio”... -

Page 26: Output
Output Gain and Polarity The Output ‘strip’ in the gain/delay view of the System Engineer panel allows you to increase or decrease the relative signal gain for any given output. The Gain value may be adjusted in 0.2dB steps from -40dB to +20dB. You can also change the polarity of the output from normal to reverse and mute it. -
Page 27: Limiters
by frequency, bandwidth and gain. The frequency is controlled over the range from 10Hz to 25.6kHz. The bandwidth, shown as Width on the screen, ranges from 0.10 octaves to 5.2 octaves. Bandwidth can be shown and adjusted as Q or Octaves (Oct). Gain is adjustable in 0.2dB increments. Any of the six Parametric filters can be used as All-Pass filters. -
Page 28: Bridge
Xmax Excursion Limiter The Excursion Limiter protects the driver against excessive linear movement of the cone and voice- coil which could otherwise cause mechanical damage. Since this movement (excursion) is largely related to the inverse of the signal frequency, drivers are prone to being damaged by very low frequencies. -

Please note that the measured impedance may depart dramatically from the rated impedance due to variations in impedance for different frequencies for a given loudspeaker. -
Page 30: Eco
power options The setup view in the System Engineer panel has a section. This allows the device to save power by going into a low power mode when it is not being used. Standby is a fast mode which saves some energy, but will wake-up very quickly if an audio input is standby time detected. -

The action is: X = Mute when connected to Ground (0v), Y = Sleep when connected to Ground (0v). Fault Relay A Three connections are available via a Phoenix connector for this relay. -
Page 33: Latency Delay
Latency delay All Digital Signal Processing, and conversion between different formats of signal – analogue/digital/network etc., necessarily introduce some delay (latency) to the signal path. Of course, we strive to minimise these latencies. Small as they are, it is sometimes useful to know their precise values. -
Page 34: Overlay Flush
Overlay Flush If the device has been used in Module Groups, and still has an active Overlay (as indicated by the Overlay indicator), these can be removed in the System Engineer application by selecting Modules Overlays mode and removing any modules for this device from all groups. See Revert to Factory Settings If you wish to erase all of your settings in the device and revert everything to factory settings, then simultaneously press and hold for 5 seconds the Up button and the Mute 1 button, then follow the... -

Alternatively, all of the operational and performance data, including the logs may be collected together into a single file by selecting File > Save Device Diagnostics. Your dealer will be able to read and interpret this data. Tipi Third Party Interface Whilst the device can be set up and controlled entirely using a dedicated control panel in the System Engineer PC application, Tipi provides a powerful yet very simple means of controlling the device using ASCII strings from a very wide range of controller devices. -
