|Menus and Mixer Window Reference|
Load/Save Configurations... (Cmd/Ctl-L)
Opens the Configuration window allowing you to select a Mixer configuration by choosing it from the dropdown menu. You may also edit and delete configurations, as well as create new configurations for the ECHODamp Mixer window by clicking the appropriate buttons. Note that these saved Mixer configurations can also include the settings for each of the Expander windows and the 2-Channel Ducker window if you first select (or create) their presets in their respective preset windows.
- Select Configuration: Choose a configuration preset for the Mixer from the dropdown menu. The Up/Down arrow keys on the keyboard will move up and down through this list.
- Save: Save altered settings to the current preset (overwrite the original settings). Click the "Enter" button (or press Enter or Return on your keyboard) to save the changes. Click the "Cancel" button (or press Esc on your keyboard) to cancel the overwrite. Note: if you attempt to overwrite the "Default" configuration, you will be prompted to confirm that is your intent.
- Save As: Create a new preset configuration from the current Mixer settings. You must give the configuration a name. Click the "Enter" button (or press Enter or Return on your keyboard) to create the new configuration. Click the "Cancel" button (or press Esc on your keyboard) to cancel the creation of the new configuration.
- Delete: Remove the current preset configuration from the dropdown menu. You will be asked to confirm that you really want to delete the configuration. Note: you cannot delete the "Default" configuration.

ECHODamp User Manual (Cmd/Ctl-U)
Opens the User Manual for ECHODamp in your computer's preferred web browser.

Connects to the ECHODamp website allowing you to check for the latest ECHODamp news and updates.
Audio Settings... (Cmd/Ctl-A)
Opens the Audio Settings window to allow the configuration of audio hardware, inputs/outputs, and sample rate.
At the top of the Audio Settings window is a dropdown menu for turning the audio in ECHODamp on and off. Audio may also be turned on and off by clicking the Audio On/Off button in the main Mixer window, or by pressing the Spacebar on your computer keyboard.
Below the Audio On/Off menu are a set of menus that allow you to choose and fine-tune the preferred audio driver for your computer. Only one audio driver can be selected at any given time. ECHODamp saves the settings for each audio driver separately and will recall the last used audio driver when you restart the program. The next four dropdown menus may or may not be active depending on which audio driver you selected in the Driver menu. When the CoreAudio driver, or either the MME or DirectSound drivers on Windows are selected, the dropdown menus allow you to change the audio input source.
Note: these menus will vary depending on the hardware and drivers installed on your computer.
Audio Driver Menu Options
- None: This setting shuts off ECHODamp audio processing.
- CoreAudio: This is the default audio driver for ECHODamp on a Macintosh. It interfaces with the system's built-in CoreAudio system and can be used with the built-in audio of the computer and any audio hardware that supports CoreAudio. You may need to install the CoreAudio driver for your interface before ECHODamp recognizes the device. With the proper CoreAudio software support, you can also work with interfaces that use ASIO.
- MME or DirectSound: (Windows only) On Windows, ECHODamp loads the MME driver by default. If you have correctly installed external hardware that supports DirectSound, it should also appear as an option on the dropdown menu.
- ad_rewire: This driver supports a standard developed by Propellerhead Software that allows sound generating applications (ReWire Devices) to send multiple channels of audio and midi to other applications (ReWire Mixers) that process and output it. Selecting the ad_rewire driver enables ECHODamp to function as a ReWire Device to route audio from ECHODamp into applications that support ReWire.
- ASIO: (Windows only) If you have a third-party audio interface that supports ASIO (a cross-platform audio hardware standard developed by Steinberg), and it is installed correctly, it will be found by the ECHODamp ASIO driver. You may have as many ASIO devices as you wish; they will all be found by the driver and will appear in the Driver dropdown menu in the Audio Settings window preceded by the word ASIO.
- ad_nonreal: This driver allows some audio software to work in non real-time mode. Real-time audio input and output are disabled under this driver, and has no practical application in ECHODamp.
- Sets the preferred sampling rate for your interface and ECHODamp. The available options will vary based on the capabilities of your interface.
I/O Vector Size
- Controls the number of samples that are transferred to and from the audio interface at one time. Smaller values tend to reduce the overall latency of ECHODamp and your interface, but will increase the load on your computer's CPU. Some interfaces do not allow you to change the I/O Vector Size, or they may only allow you to do so in the dedicated driver application that came with the interface.
Signal Vector Size
- Controls the number of samples that ECHODamp processes at one time. In general, larger sizes produce better performance. For best results, set a large Signal Vector Size value that divides evenly into the value you set for the I/O Vector Size (ex: I/O Vector Size = 256, Signal Vector Size = 128 or even 256).
Enable/Disable Audio Channels Buttons
- Enable the channels you will use by clicking the appropriate button (when button is illuminated, channel is enabled). Selecting only the channels you will use helps reduce processor load on your computer by eliminating unnecessary audio processing.
Input/Output Map Button
- Opens the Input/Output Map, allowing you to manually select which inlets and outlets on your interface are mapped to the channels in ECHODamp. By default, the first 8 hardware inputs and outputs are routed into and out of ECHODamp.
Calibration Tools... (Cmd/Ctl-T)
Opens the Calibration Tools window allowing you to calibrate audio levels between VTC sites and measure round-trip latency. For more information on using the Calibration Tools, see Calibrating Your Audio and the appropriate section in the Secondary Windows Reference.
Audio Enabled (Spacebar)
Turns audio processing on and off for ECHODamp. A check mark will appear next to this menu item when audio is enabled. You can also turn audio processing on by clicking the AUDIO ON/OFF button in the Mixer window, or by simply pressing the Spacebar on your computer keyboard.
Monitor Controls... (Cmd/Ctl-M)
Opens the Monitor Controls window allowing you to create separate mixes for the Control Room and for an Audience if desired and you have the appropriate hardware configuration. For more information on using the Monitor Controls, see the appropriate section in the Secondary Windows Reference.
By default, the sidechain signal routed to the 2-Channel Ducker is post-fader, and goes through the channel strip first (including the Downward Expander) before being sent on the sidechain bus. If you wish to have the sidechain audio bypass the channel strip and go directly to the sidechain bus, select this option. A check mark will appear by this item when it is selected indicating that the sidechain audio is pre-fader. Even if you select Pre-Fader, the audio will still pass through the Hi-Pass filter before entering the sidechain bus.

ECHODamp operates primarily from the Mixer view. The program is designed to operate and "feel" much like a typical audio mixer with controls that are familiar and intuitive to anyone with a basic working knowledge of audio mixers.
