Page 5: Thanks And Unpacking
Thanks and Unpacking Thank you for choosing a Danley Sound Labs DNA5K4 series amplifier system for your application. Please spare a little time to study the contents of this manual, so that you obtain the best possible performance from this unit. -
Page 6: Introduction And Key Features
Introduction and Key Features Introduction The DNA5K4 amplifier systems from Danley Sound Labs integrate light-weight power supplies, high power sonically transparent class D amplifiers, complete system monitoring and a fully featured USB or network controlled 24 bit 96kHz DSP processing platform as standard. -
Page 7: Mechanical Installation
Mechanical Installation The DNA5K4 amplifier system is designed to be mounted in a standard 19” rack enclosure. Where the amplifier is used in a fixed installation, it is possible to use only the front panel 19” rack mounting holes to mount it in a standard rack enclosure. If the amplifier is mounted in a mobile rack it is recommended that the rear rack mounting kit is fitted so Page 7 of 31... - Page 8 the amplifier can be well supported. 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 DNA5K4 amplifiers without ventilation gaps between them but it is essential that an unobstructed flow of clean air is available from the back of the unit to the front.

Page 9: Ac Power Connection
AC Power Connection WARNING! THIS APPLIANCE MUST BE GROUNDED. The amplifier must always be connected using a 3-wire, grounded AC supply. The framework of the rack mount enclosure should also be connected to the same grounding circuit. The unit should never be operated unless the AC power cable ground is correctly terminated;... -
Page 10: Audio Connections
Audio Connections For each amplifier channel there are female and male XLR input connectors, which are wired in parallel. Typically the female connector is used for the audio input, the male XLR connector being available to link the same audio signal to another amplifier channel. The HOT, + or ‘in phase’... -
Page 11: Using Unbalanced Connections
Using unbalanced connections When connecting the DNA5K4 amplifier to an unbalanced audio source, the signal conductor should be terminated to XLR pin2 and the cable screen terminated to both pins 1 and 3. Input XLR unbalanced connection Pin 2 HOT + Pin 1 Shield In bridged mode output channel 1 signal chain provides the signal for the 1 &... -
Page 12: 100V Line Operation
The Speakon connector for amplifier channel 1 carries the output for amplifier channels 1 and 2. In addition this connector can also be used if the pair of amplifier channels is being operated in bridged mode. More than one speaker can be connected to each channel provided the total impedance per channel is not less than 2 ohms. -
Page 13: Front Panel
Front Panel Power Switch The DNA5K4 amplifier is fitted with two dual channel power modules. As the power modules operate independently there is a separate power switch for each. When the power switch is operated, the protect indicator will flash while the DSP and amplifier control systems are prepared. -
Page 14: Protect
Protect The DNA5K4 DSP amplifier system has sophisticated protection and monitoring systems which keep the amplifier within its safe operating window whenever possible. This indicator lights when the protection systems are active in any way. User DSP indicator Using the PodWare PC application the user can introduce audio processing such as EQ, gain and delay. -

equipment in the network, then you will need to use an Accessory Power Supply to power the Interface. The Aux In socket may be used to select between a number of ‘Voices’ that may have been programmed into the DNA5K4 using factory files (*.dfa) supplied by your vendor. These files would be loaded into the DNA5K4 via the PodWare application. -

about the DNA5K4 control panel, click the “?” in the right-hand corner of the DNA5K4 control panel in PodWare. Amplifier Channels It is important to realize that each two channel amplifier section contains its’ own DSP. So a four channel amplifier is logically split into two sections, each with two channels. There is an independent two channel control panel associated with each section. -

Main Control Panel The Input area allows you to adjust the input sensitivity of each input of the amplifier, and to change the polarity of each input, allowing you to reverse the phase of the loudspeakers fed from that input. The Output section allows you to control the output drive level of each amplifier. -

Page 22: Loading Factory Presets
Loading Factory Presets Your loudspeaker vendor may provide you with one or more ‘preset library’ files which contain settings for specific loudspeakers. These take the form of Factory files (Device FActory files (with file extension .dfa). When you load preset factory settings into this type of device, the current user settings will be preserved since the factory settings will only overwrite the default factory DSP settings rather than the User DSP settings. -
