4.2.1Input Filtering

Deemphasis

The Deemphasis parameter controls whether or not 50/15 ∝s digital deemphasis may be applied to the main input channels before the Dolby Digital encoding process is performed. If Deemphasis is set to Disabled, deemphasis will never be applied and the emphasis channel status bit of input signals will be ignored. If the parameter is set to Automatic, digital deemphasis will automatically be applied to input signals if the emphasis channel status bit indicates 50/15 ∝s pre-emphasis has been applied. The state of Deemphasis and the channel status bit will be ignored whenever pre-encoded bitstreams are being received, Pass Through mode is active.

DC Highpass Filter

DC Highpass Filter controls whether or not a DC blocking 3 Hz highpass filter is applied to the main channel inputs before the Dolby Digital encoding process.

Bandwidth Lowpass Filter

Bandwidth Lowpass Filter controls whether or not a bandwidth limiting lowpass filter is applied to the main input channels before the Dolby Digital encoding process.

LFE Lowpass Filter

LFE Lowpass Filter controls whether or not a 120 Hz lowpass filter is applied to the LFE channel before the Dolby Digital encoding process. This parameter is ignored if the LFE channel is disabled. This parameter is not available on the DP567.
