Page 15: Configuration Software
USER’S MANUAL HMD8 DSP/ 6. CONFIGURATION SOFTWARE This section describes the main features of the configuration software: Navigator. The software was designed to be adopted by all products with onboard DSP in the Hertz marine catalog and future ones: when you connect the device to the software, it automatically configures itself to display the interface of that specific device connected.
Page 16: Save And Load The Configuration
USER’S MANUAL HMD8 DSP/ SAVE AND LOAD THE CONFIGURATION The software provides the ability to save the current configuration to a file, upload one already saved on your PC and other important features. These are available on the top command bar, as shown in the image below. OPEN Load configuration from a file saved on the PC.
Page 17: Audio Setup
USER’S MANUAL HMD8 DSP/ Settings The image below shows the general settings panel: Sampling frequency: allows you to set the sampling frequency used by the audio processor (DSP). Language: allows you to set the software interface language. Unit of measure: allows you to set the unit of measurement choosing between centimeters (cm) or inches (in). WARNING: the DSP mounted on this device is capable of processing the signal only at 48 kHz.
Page 18 USER’S MANUAL HMD8 DSP/ 6.4.1.3 OUTPUT CHANNELS DEFINITION The output channels represent the points where the sound is reproduced, i.e. where the speakers are physically connected. Ultimately, the output configuration is the one that most characterizes the audio system. It is important to have the system project clearly in mind before starting: the type and the position of loudspeakers, the need for bridged channels, how many listening areas must be created.
Page 19: Sources
USER’S MANUAL HMD8 DSP/ 6.4.1.8 MEMORIES CONFIGURATION The memories act on all the output channels and serve to give a particular nuance setting to the system. Unlike the previous settings which are an essential and fixed part of the setup, the memory can be activated or deactivated by the end user while listening.
Page 20: Input Channels
USER’S MANUAL HMD8 DSP/ 6.4.3 INPUT CHANNELS The Input channels depend directly on the currently selected source. Each source has its number of inputs and its type of inputs. In this amplifier the input channels are analog for the MASTER source and digital for the OPTICAL source.
Page 21 USER’S MANUAL HMD8 DSP/ • DIGITAL INPUT CHANNELS The image below shows the inputs panel for the OPTICAL source. Remark: for digital input channels sensitivity should not be adjusted. The image below shows one of the input settings panels for the OPTICAL source. The input channel can be: •...
Page 22: Output Channels
USER’S MANUAL HMD8 DSP/ 6.4.4 OUTPUT CHANNELS The output channels represent the fundamental elements of the audio system: in the final analysis they can be considered like installed speakers. In the software, each channel has a color associated with it: when a specific channel is selected, the graphic interface elements that concern it take up that same color.
Page 23: Output Channel Groups
USER’S MANUAL HMD8 DSP/ 6.4.5 OUTPUT CHANNEL GROUPS Each output channel can be associated with one or more groups. If the output channel is associated with one or more groups, its volume will also be adjusted according to the volumes of the associated groups. The association with the groups can be performed in the output channel settings panel.
Page 24: Listening Zones
USER’S MANUAL HMD8 DSP/ 6.4.6 LISTENING ZONES The idea behind the zones is to provide the possibility to divide the output channels when they are spatially distant from each other so much as to consider them in different environments. The division into zones is therefore justified if the layout of the output channels is distributed over different environments.
Page 25: Mixer
USER’S MANUAL HMD8 DSP/ 6.4.7 MIXER The mixer allows you to adjust the mixing percentage of the input channels on each output channel. The mixer is accessible through the top command bar. To exit the mixer, press the related button again. The image below shows the graphic interface of the mixer.
Page 26: Delays And Distances
USER’S MANUAL HMD8 DSP/ 6.4.8 DELAYS AND DISTANCES This setting is based on an automatic system that calculates the time needed for the sound to get from the speaker to the listener’s ear. Preliminary remarks Sound moves through the air at a speed of 343 m/sec (1.125 ft/sec) at a temperature of 20 °C (68 °F). If you know the distance from the sound emission point, you can then calculate the time the sound takes to get to the listener’s ear.
Page 27 USER’S MANUAL HMD8 DSP/ • DISTANCES The following image shows the mini map panel and the functions related to the position of the speakers. This panel is a miniature map showing the position of the speakers belonging to the selected zone. The icon relating to the currently selected output channel is highlighted on the map.
Page 28 USER’S MANUAL HMD8 DSP/ • LOUDSPEAKER POSITION PANEL The image below shows the loudspeaker position panel and its functions. Maximum distance limit: this function is active by default and allows you to move the loudspeakers inside the red dotted line. This limit represents the maximum distance of the speakers allowed by DSP delay lines; if all the speakers in the map were moved away from the listening point, the red circle would increase its radius and a gray circle will appear in the center to indicate the prohibited area within which the speakers cannot be positioned.
Page 29 USER’S MANUAL HMD8 DSP/ Confirmation button: it updates the speaker positions and calculates delays. The distances set are displayed on the output channels panel. By clicking on this button, a warning message is shown as in the following image: With a check mark in the appropriate boxes it is possible to choose the sources to which the delays should be applied.
Page 30: Crossover
USER’S MANUAL HMD8 DSP/ 6.4.9 CROSSOVER With the crossover section it is possible to set different bands for every output channel. Remark: the output channel you are acting on is indicated by the foreground color of the crossover panel. The image below shows the crossover parameters that it is possible to set: Type: allows you to choose the type of crossover.
Page 31 USER’S MANUAL HMD8 DSP/ 4. BAND PASS The Band Pass type is the combination of the previous two (high and low pass); it is possible to select the name, slope and frequency for both filters. • NAME After the type has been selected, the name filter option will display the following models: 1.
Page 32: Equalizer
USER’S MANUAL HMD8 DSP/ 6.4.10 EQUALIZER With the equalizer it is possible to emphasize or attenuate some frequencies rather than others. The equalizer setting can be performed in two ways: • Graphic equalizer • Parametric equalizer The following functions are available for both the graphic and parametric equalizers. Equalizer type selection: allows you to select the equalizer type between graphic or parametric.
Page 33: Memories
USER’S MANUAL HMD8 DSP/ After selecting the filter type it is possible to set the Gain, Frequency and the Form factor (Q), except for Flat where it is not possible to set any parameters. The minimum and maximum Gain is -12 dB and +12 dB. For Notch or All-pass the gain is set to 0 dB and cannot be changed.
Page 34 USER’S MANUAL HMD8 DSP/ • MEMORIES SETTINGS PANEL The image on the side shows the settings panel for the memories. The memories can be: • renamed; • disabled / enabled. WARNING: when a memory is disabled it is definitively unusable. It is not possible to rename or customize it.
Page 35 USER’S MANUAL HMD8 DSP/ • PARAMETRIC EQUALIZER The following functions are available for both the graphic and parametric equalizers. Equalizer panel: allows you to select the memory equalizer filter panel. Delta volume panel: allows you to select the memory delta volume panel. See Memory volume (see sec.
Page 36 USER’S MANUAL HMD8 DSP/ • PARAMETRIC EQUALIZER With the parametric equalizer it is possible to set more parameters for every section than the graphic equalizer. WARNING: the parameters of each section of the parametric equalizer are linked to each other. When a parameter is changed, it may cause changes to other parameters.
Page 37 USER’S MANUAL HMD8 DSP/ MEMORY VOLUME 6.4.11.2 The selected memory allows this further customization for the output channels volumes. Remark: this function is applied to the output channels only when the memory is selected. Delta volume checkbox: allows you to enable or disable this additional feature of the selected memory.
