NOTE: The DTX-44D and DTX-6464D have fixed DSP modules, they cannot be changed. Adding and Removing DSP Modules DTX-88D, DTX-1616D and DTX-3232D allow for the customization of DSP Modules on a per channel basis. -
Page 27: Input Source
USERS GUIDE Cancel: Exits ‘Edit Module’ mode and discards changes. Input Source The Input Source Module is a fixed module that exists on every input channel of every DTX device. It provides basic input parameters for the selected channel. Since this is a fixed Module, it does not consume one of the five Module Slots available on some DTX models. -
Page 28: Expander
USERS GUIDE Expander Expanders are helpful dynamic processing tools that increase the dynamic range of an audio signal. They are essentially the opposite of a compressor, which decreases the dynamic range of an audio signal. The most fundamental difference between and expander and a compressor is that while a compressor engages when a signal is above a defined threshold, an expander engages when a signal drops below a... -
Page 29: Automatic Gain Control (Agc)
USERS GUIDE Ratio: Refers to the compression ratio. The ratio determines how much attenuation to apply to a signal that has overshot the threshold level. A lower threshold will reduce a greater portion of the signal, while a higher threshold will reduce only the loudest peaks and leave the rest untouched. -
Page 30: Parametric Eq
USERS GUIDE typically be set just above the noise floor. This assures that the noise floor itself will not trigger the AGC, but any signal above that will. Ratio: Sets the desired ratio between input signal and output signal. Target Threshold: Sets the desired output signal level. If the signal is higher than the threshold, the controller will compress the signal in proportion. -
Page 31: Graphic Eq
USERS GUIDE Frequency (Hz): Sets the center frequency of the filter. Gain (dB): It refers to the amount of gain or attenuation applied at the center frequency. Q : Q Represents ‘Quotient of Change’ or the bandwidth. This sets how wide a swath of frequencies are affected surrounding the center frequency. -
Page 32: Adaptive Feedback Control (Afc)
USERS GUIDE Frequency Bands: Gain control for the specified frequency. Value ranges are from +12 dB to -24 dB (attenuation). Narrow/Normal/Wide: Selects from one of three preset Q-values. This setting applies to all frequency bands. Reset: Resets gain values for every frequency band to 0 dB and turns OFF the Graphic EQ module. ON/OFF: The Graphic EQ has a master on/off switch which is used to enable or disable the module. - Page 33 USERS GUIDE When the signal returns to below the threshold, all settings are returned to their pre-feedback event state. Feedback Threshold: Positively defines what is NOT a feedback event. Any signal that is below this threshold is not considered feedback. Setting this threshold too high can diminish the effectiveness of the AFC. Filter Depth: Sets the maximum attenuation of a single filter.
-
Page 34: Gate
USERS GUIDE If a speaker is included among the devices used, it is recommended to use a compressor/limiter module on those outputs for additional protection. You should set an appropriate limiter to make sure that the speaker will not get damaged even if all notching filters slots are used or the feedback inhibitor cannot effectively control the feedback, such as in the case of excessive system gain. -
Page 35: Ducker
USERS GUIDE Ducker A Ducker is a device used for lowering the level of one audio source based on the presence of another audio source. Duckers are often used in paging systems to lower the level of background music during a page. -
Page 36: High And Low Pass Filter
USERS GUIDE microphone. For example, consider music and announcements in a bar or restaurant setting. When the bar is empty, the ambient sound is low and thus, the program (music/announcements) do not to be too loud. As the bar fills, the ambient noise gets louder, and the program will get drowned out in the noise floor of the room. -
Page 37: Delay
USERS GUIDE The Butterworth filter is a type of signal processing filter designed to have as flat frequency response as possible (no ripples) in the passband and zero roll off response in the stopband. However, one main disadvantage of the Butterworth filter is that it achieves this pass band flatness at the expense of a wide transition band as the filter changes from the pass band to the stop band. -
Page 38: Output Setting
USERS GUIDE Output Setting The Output Setting Module is a fixed module that exists on every output channel of every DTX device. It provides basic output parameters for the selected channel. Since this is a fixed Module, it does not consume one of the four output Module Slots available on some DTX models. -
Page 39: Dsp System Modules
USERS GUIDE DSP System Modules Gain Sharing Auto Mixer The Dash Gain Sharing AutoMixer is a multichannel mixer that automatically lowers the level of non-active audio sources such as microphones while simultaneously riding the level of active sources to maintain the desired target gain. This eliminates the need for tedious and often impractical live mixing of audio sources. -
Page 40: Gating Automixer
USERS GUIDE Mute: Mutes the output of the AutoMixer. ON/OFF: The Auto Mixer has a master on/off switch which is used to enable or disable the module. The ‘Gain Sharing AutoMix’ indicator will be green when the module is ON. Channel Control Parameters Fader/Gain: Sets the channel gain. - Page 41 USERS GUIDE In addition to a Gain Sharing AutoMixer, Dash provides the option of a more traditional Gating AutoMixer (Relative Threshold). When in Edit Module mode, right clicking on the AutoMixer slot in the top center of the Home Tab, provides the option of using either a Gain Sharing AutoMixer or a Gating AutoMixer.
-
Page 42: Acoustic Echo Cancellation (Aec)
USERS GUIDE AutoMixer: Enables AutoMix participation of the selected channel. Mute: Mutes the channel. NOTE: Mute is after the input to the AutoMix engine. A muted channel may still influence the gain adjustment of other channels in the AutoMix. Default: Sets the default channel. When all other channels are gated, the single default channel will be opened. Acoustic Echo Cancellation (AEC) Acoustic Echo Cancellation (AEC) is important for audio teleconferencing when simultaneous... -
Page 43: Automatic Noise Suppression (Ans)
USERS GUIDE ON/OFF: The AEC has a master on/off switch which is used to enable or disable the module. The ‘AEC’ indicator will be green when the module is ON. Note: Use the output of the AEC to route the resulting audio in the Matrix. Do not add the both the AEC and the local source into the Matrix together or the desired effect will be lost. -
Page 44: Camera Tracking
Tracking threshold a camera preset can be changed and/or a custom serial command can be sent. For example, a preset can be sent to change the preset of a camera and simultaneously send a command to an Aurora VTX decoder or a video switcher to change which camera is being displayed. - Page 45 USERS GUIDE Channels This section is used in conjunction with the Voice Tracking settings. Each input channel in the DSP can be selected and optionally enabled to participate in the Automatic Voice Tracking Camera Control. Channel No: Selects the current input channel.
