V = 331m/s + (0.6m/s/C) * T

The speed of sound at room temperature is 346 meters per second. At freezing temperatures sound travels at 331 meters per second. V is the speed of sound and T is the temperature of the air. This formula finds the average speed of sound for any given temperature (celcius). The speed of sound is also affected by other factors such as humidity and air pressure.

Editing

Editing mode is where the Edit Mode (Standard Edit or Full Edit) is set. The DC-One defaults to Standard Edit mode wherein, input and output channel parameters are appropriately linked. (See page 50 for more.) In Full Edit mode, no parameter links are enforced, regardless of the configuration selected. Use the <SELECT> key to navigate to the EDITING parameter to choose your editing preferences.

Lock - Front Panel Access

A lockout mode has been provided for the installer to protect the system settings from being modified by a user. This can be set from the front panel or from the GUI software.

For more on this see DC-One GUI Quick Start Guide

From the front panel -

Use the <SELECT> key to navigate to the Lock menu. Use the VALUE key to choose your four digit code. Then use the <SELECT> key navigate to the Store parameter, to lock or unlock front panel editing.

From the GUI -

Open the DC-One’s GUI and choose Front Panel Access from the Window pull-down menu. Doing so will bring up the Front Panel Access GUI that will present the unit’s

currently loaded state including preset (U## or F##), DSP Blocks and Parameters. Any or all of the DC-One’s DSP Blocks and/or individual parameters within the DSP blocks can be locked or hidden from this window by selecting the corresponding box to engage the lock icon. For example, an installer may chose to lock and hide all Limiter parameters, lock all Crossover parameters but leave them visible, and lock the last 5 Input PEQ filters, leaving the first 4 available for the user to edit and modify.
