6.13 - AutoWarmth® Insert

The Fletcher-Munson Equal-Loudness curves show that the perception of low frequency signals decreases quickly with decreasing volume. The DriveRack 4800 and 4820 offer the AutoWarmth® Insert module on each output (Insert 1) to compensate for this perceived loss in low frequencies. AutoWarmth is a patent pending process that compensates for the naturally occurring perceived loss of low frequency at low signal levels. The result of using AutoWarmth is warm and balanced signal even at low signal levels.

AutoWarmth On/Off switch

This parameter turns the AutoWarmth function on and off.

Threshold fader

The Threshold sets the level at which AutoWarmth begins to work. Signals below the Threshold are pro- cessed to increase the Bass response in proportion to the overall volume of the signal. Above the Threshold there is no processing. The Threshold meter will light green when the threshold has been crossed and AutoWarmth is active. The Threshold range is between -60 and 0 dBFS. To set the Threshold, turn AutoWarmth off and adjust the Master Gain to the desired listening level. Turn AutoWarmth on and adjust the Threshold until the Threshold Meter is toggling on and off. Now as the volume decreases below the Threshold, the bass will gradually increase. Be careful when using AutoWarmth followed by an AGC. The AGC can add gain when the signal is below the AutoWarmth threshold resulting in overcompensated Bass.

Amount fader

The Amount parameter controls how much bass is added. A setting of 1.00:1 compensates for the per- ceived loss of bass by inversely matching the Fletcher-Munson Equal Loudness curves. Higher settings (greater that 1.00) cause more bass compensation; lower settings result is less bass compensation. The Amount parameter is adjustable between 0.25:1 and 4.00:1.
