Page 7: Thanks And Unpacking
Canadian ICES-003. Thanks and Unpacking Thank you for choosing the APG DMS48 processor 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. All APG products are carefully engineered for world-class performance and reliability. -
Page 8: Introduction And Key Features
Below is a list of key features, followed by some information on the major advancements of the DMS48 feature set. Key Features APG minimal signal path design Bandwidth: 96kHz sampling frequency provides for a nominally flat response beyond... -
Page 9: 3.3 Drive Modules
3.3 Drive Modules Drive Modules The DMS48 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 10 3.5 FIR Linear Phase Equalisation 3 INTRODUCTION AND KEY FEATURES this EQ is not linear phase, then the zones where the speakers combine may suffer frequency response anomalies.

Page 11: User Guide
This user manual gives a progressively more detailed description of the functions of the APG DMS48 processor. 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. A detailed explanation of the front and rear panel controls and indicators is contained in the next section. -
Page 12: Input Clip/Mute Indicator
The AES3 active indicators show that the AES3 input/output is active for that pair of channels. AES3 transmits two channels down one XLR cable. On the DMS48 each pair is carried by the odd number connector such as, 1+2 will be carried on XLR connector 1 and 3+4 will be carried on XLR 3 and so on. -

A.2.2 Networked Audio Ports The DMS48 has the option for networked audio ports; if none are required a blanking plate will be fitted. There are several options for networked audio including Dante and AVB. For a full list please consult your vendor. -

85V to 240V, 50/60Hz without re-configuration. Note: The DMS48 must be earthed to a suitable power earth; failure to do so may affect performance and/or operation and will invalidate warranty and could be potentially hazardous. -
Page 15: B.2 Drive Module Presets
DSP input Figure 4: Main screen The DMS48 uses Drive Module presets, which are defined as a number of outputs driven from one DSP input. This system allows for better flexibility and greater functionality when loading and storing presets. Drive modules allow for a less processor centric and more speaker orientated system design. -
Page 16: Factory Presets
B.4 Factory Presets B OPERATION The DMS48 has 45 drive module preset locations and these can be stored and recalled from the <IN> pages, for the channel being viewed. To design a new crossover, press the desired <IN> or <OUT> button to enter the pages where the parameters for each of the channels are shown. -
Page 17: B.5 Storing Presets
0.0dB 0.0dB In addition to the usual analogue inputs, the DMS48 can also accept AES3 digital inputs. The same physical XLR sockets are used for both Analogue and AES3 inputs; the function of these being determined by the Source parameters in the Input Route menu. The Input sockets 1 and 3 are used to input pairs of AES3 channels, so adjusting the input to AES3 on either Input 1 or Input 2 will cause the other channel to change also. -
Page 18: Gain And Polarity
DMS48. Again, it is possible to set the relative gain between an Analogue input and the Digital Audio Network (Dante) using the Input Route Dante gain parameter. This device will automatically select the correct sample rate from the incoming stream. -

Analog DSP A In addition to the usual analogue outputs, the DMS48 also allows outputs to be sent digitally using AES3. The same physical XLR sockets are used for both Analogue and AES3 outputs; the function of these being determined by the XLR parameters in the Output Route menu. -
Page 21: D.5 Lir Crossover Filtering
D.5 LIR Crossover Filtering LIR Crossover Filtering Unique to APG, Linea Impulse Response (LIR) crossover filtering gives a Linear Phase crossover which has a constant delay regardless of frequency (unlike other types of crossover which delay different frequencies to a different extent, thus smearing the arrival time). The LIR crossover can thus be described as having a flat Group Delay response, and thus entirely free of Group... -
Page 22: Tmax Thermal Limiter
D.7.4 Amplifier Gain Expressed in dB, this is the gain of the amplifier which the output of the DMS48 is feeding. This value must be entered to allow the DMS48 to correctly calibrate the thermal and excursion limiter for the amplifier in use. -

Warning Do NOT use Static mode unless your IT system specifically requires it. Auto mode should always be used where possible since in this mode, the DMS48 device can always be discovered by the PWAPG application. When in Static mode, a warning will flash on the Default screen. -
