Page 12: Installation Instructions
INSTALLATION INSTRUCTIONS Mechanical Installation The DQ 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. -

supported with a rear rack mounting kit (part number ZA1182). Damage caused by insufficient support is not covered by the warranty. 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 DQ 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: The User Guide
The User Guide This user manual gives a progressively more detailed description of the functions of the EM Acoustics DQ Series Advanced System Amplifiers. A single page quick reference guide is provided for those users who are experienced with this type of equipment and just need to know how to ‘drive’ the front panel. -
Page 15: Introduction And Key Features
Introduction and Key Features Introduction The EM Acoustics DQ Series Advanced System Amplifiers represent 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 16: Drive Modules
Drive Module Preset (i.e. any driver in a loudspeaker subsystem). Being as the majority of EM Acoustics’ systems are passive, and only require one amplifier channel, the Component presets are used widely – see later in this manual for more detail. -
Page 17: Fir Linear Phase Equalisation
The shape of the LIR crossover filter is quite similar to a 4 order or 24dB/Oct Linkwitz-Riley filter, and maintains zero phase difference between the adjacent bands across the crossover region to keep the polar response rock steady. FIR Linear Phase Equalisation The Input High-Shelf Equalisers use Finite Impulse Response (FIR) filtering to produce Linear Phase equalisation;... -
Page 18: Audio Connections
Audio Connections Input Connections For each input channel there is a female XLR connector for analogue inputs. There is also one female XLR for one stream (two channels) of AES3 digital audio. Note that only two channels of AES3 digital audio are available. -
Page 19: Amplifier Output Connections
Amplifier Output Connections The DQ Series amplifiers are fitted with one Speakon connector per amplifier channel. The appropriate conductor terminations are shown below and on the rear panel of the unit. Amplifier output connections – 44M Amplifier output connections – DQ Series Speaker - Speaker + Additionally, the channel 2 output is duplicated on the Speakon... -
Page 20: Load Matching

Page 21: Panel Layouts
Panel Layouts 1. Input Signal Indicators- A set of five indicators show “Sig”, “-12”, “0dBu”, “+6” and “+12” and “Clip (mute)” for each of the DSP inputs “A” “B” “C” “D”. The signal present Indicators operate at approximately –40 dBu. The Clip/mute Indicators warn the user of input overload and operate at 1dB before clip. - Page 22 Relay output- This isolated relay output may be used to indicate abnormal conditions to external monitoring apparatus. See Fault Relay Power Inlet- The unit should be connected to a suitable mains electricity supply using an earthed Powercon connection power lead. The device has a switch mode power supply that is capable of operating with a nominal mains voltage of 100V to 230V, 50/60Hz without re-configuration.

Page 23: 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 screen will inform you of its progress. Once this is complete the display will then show the Home screen indicating drive module configurations. -

AES3 or networked audio feeds, can drive any number of DSP inputs. Component Presets A Component Preset represents the processing for just one output. Due to EM Acoustics’ product predominantly requiring only one amplifier channel, we use Component presets more frequently than Module presets. -
Page 26: Factory Module Presets
Factory Module Presets Factory Presets The DQ Series device contains 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. -

When the Digital Audio Network input is installed and routed, the “Net Audio” indicator above the encoders will illuminate. This indicator will come on even if there are no cables plugged into the networked audio port on the Device. -
Page 29: Parametric Equalisation
The Hardman type filter is always described by its order as the filter becomes progressively steeper rather than following a linear slope so a dB/octave description is not accurate. Parametric Equalisation There are nine stages of equalisation available for each input channel, three shelving filters and six parametric filters. -
Page 30: Delay
Delay The delay page controls the amount of delay associated with the output channel selected and is adjustable from 0 to 998ms. The delay parameter is adjustable in fine steps at low values; the adjustment becomes progressively coarser as the value increases. High and Low pass Filters High pass and low pass crossover filtering is provided for the output signal. -
Page 31: Limiters
Please note that whilst the Limiters in this product offer protection for amplifiers and drivers, they can never protect from all possible scenarios, therefore EM Acoustics is not responsible for any damage which might occur. -

low-frequency response, effectively limiting the linear excursion to below the X-max specification of the driver. To set the limiter up, it is necessary to know the shape of the family of Excursion vs. Frequency curves of the driver for various drive voltage levels. A curve should then be chosen where the slope is high where it passes though the specified X-Max value for the driver. -
Page 33: Stereo Linking
Stereo Linking Stereo linking is available between DSP Drive Modules A & B and between C & D. Changing a parameter in either of the stereo linked Drive Modules will change the other linked Drive Module. Stereo linking is controlled by the STEREO page in the “UTILITY” menu. Note: Stereo linking will only work when the linked Drive Modules are of equal size. -

however as there is no negative consequence to doing this since ‘wake-up’ on detecting the presence of an audio input signal is instantaneous. The Standby Now ‘parameter’ allows the amplifier to be put into standby mode manually when it is not being used. -
Page 35: Ip Troubleshooting
IP Troubleshooting If System Engineer cannot connect to the device: • A Router acting as a DHCP server is highly recommended as this provides the most trouble- free way of administering IP addresses. Always switch on any DHCP server before connecting either the computer or Amplifier to the network. -
