USER'S MANUAL 8.8 SET DISTANCE AND DELAY bit One HD / 8 7 This setting is based on an automatic system allowing to calculate the time the speaker sound takes to get to the listener’s ear (Fig.1). Preliminary remarks Sound moves through the air at a speed of 343 mt/sec (1.125 ft/sec) and at the temperature of 20°C (68°F). If you know the distance from the sound emission point, you can then calculate the time sound takes to get to the listener’s ear.
USER'S MANUAL bit One HD / 8 Example of time delay setting (Fig.4): 1. choose the system listening point. To identify the listening point, choose an ideal point located at the center of the listener’s (driver or passenger) head. For the front central and rear central points choose an intermediate point between the two listeners. 2. measure the distance between each loudspeaker or group of loudspeakers and the listening point in a straight line (“as the crow flies”) (Fig. 4).
USER'S MANUAL 8.9 EQ SETTINGS bit One HD / 8 8 The bit One HD software provides a series of equalizers to be managed on screen which, with extreme versatility, provide for an optimal calibration of the audio system. The user can operate on the equalization of the Master or AUX analog inputs by choosing the “Input EQ” option, on the whole system equalization by choosing the “Main EQ” option and on the bit One HD single output channels equalization by choosing the “Output EQ” option. 1.
