Processing Parameters

'AVG ATTACK' Controls the average attack rate of the limiter. This control is a modifier control that

scales from the peak attack control. The attack time can be varied between 1 and 10 which corre-

spond to peak attack time / 2 to peak attack time / 1000 on a semi-exponential scale. The AVG attack

control determines the dynamics of the dual time constant system and how control is shared between

the peak and average circuits.

'AVG DECAY' Controls the average release/decay rate of the limiter, the time the limiter takes to

respond to a decrease of input level. The DECAY time can be varied between 1 and 10 which corre-

sponds to 200mS to 5000mS on a semi-exponential scale.

'MIXER' menu. Each band can be adjusted over a small range to provide small EQ changes. These controls

are limited in range to prevent excessive drive into the final peak limting stages and excess distortion being

introduced.

BAND1MIX: -3dB to +3dB of level adjustment is available.

BAND2MIX: -3dB to +3dB of level adjustment is available.

BAND3MIX: -3dB to +3dB of level adjustment is available.

BAND4MIX: -3dB to +3dB of level adjustment is available.

The 'LOOK-AHEAD' menu contains the look-ahead limiter controls that form the final peak limiting stages of

the DSPXmini-HD.

'BASS CLIP' Sets the bass clipper threshold. The range is 0 dB to -6 dB below final look-ahead limiter

threshold.

'LP FILTER' A high frequency filter adjustable over a range of 4-20 kHz. This control can be used to tame

the artifacts of subsequent perceptal coding, especially when used with very low bitrates.

'DRIVE' Controls the drive into the main output look-ahead limiter that defines the systems peak output

ceiling. Adjustable over a -6dB to +6dB range.

The 'OUTPUT' menu contains all of the controls relevant to the analog and digital outputs.

The 'ANALOG' menu contains the controls relevant to the analogue outputs.

'OUTPUT LEVEL' Controls the output level of the analogue output. Range is -12dBu to +24dBu

The 'DIGITAL' menu contains the controls relevant to the AES/EBU digital outputs.

'OUTPUT LEVEL' Controls the peak output level of the digital output. Range is -12dBFS to 0dBFS

'SAMPLE RATE' This parameter sets the output sampling rate for the AES/EBU digital output. The avail-

able rates are 32 KHz, 44.1 KHz, 48 KHz, follow digital input rate and follow external sync rate.

The 'SCHEDULE' menu contains all the controls for the dayparting (REAL TIME CLOCK) preset switch

ing.

'TIME' Sets the time and day of the DSPXmini-HD’s Real Time Clock.

'DAYPARTING ON/OFF:

Enables or disables the scheduling.

'DP(X) ON/OFF' Enables or disables an individual daypart schedule.

'DP(X)' Sets the preset to switch to when this daypart is triggered.

'DP(X) START' Sets the start time day and time of the daypart. There is also an ‘ALL days’ option.

'DP(X) LENGTH' Sets the length in minutes that the daypart will run for.

The 'SYSTEM' menu contains all the system controls (non processing) such as remote control and secu-

rity
