DSP 600 Userpanel
The DSP 600 Userpanel provides access to the controls and indications on the DSP 600 front panel.
Indications and Functions of the DSP 600 Userpanel
Element Description
The level meter displays are meant for visual monitoring of the input signal levels,
individually showing the peak value of the correspondent input signal in dBu. The input
control should be set to a position so that the meter instruments indicate a level
between -6 and -12 dB. To prevent internal clipping, make sure that the CLIP LEDs are
not lit.
In online mode the LCD display is identical on the DSP 600 Userpanel and the device.
These LEDs indicate the peak level of the corresponding outputs. The level is shown as
headroom relative to the D/A clip or limiter threshold, as selected in the DSP 600
menu. The DSP 600 should be operated in a range, so that the clip-LEDs are not lit.
Otherwise, this could lead to internal clipping.
Each output channel has a four-segment gain reduction meter that shows the gain
reduction of the output channel Limiter on output signal; from -3dB to -12dB.
Each output channel has a four-segment function display for informational purposes
only. For any given configuration pos- sible with the DSP 600, an output channel may
be identified as a sub, low, low/mid, mid, mid/hi, hi or full range output. One or two
adjacent LED are displayed to indicate all possible output bandpasses. (Full range is
indicated by no lit LED’s.)
Each output channel has a lighted Mute button. Pressing the Mute button turns off the
output of that channel. The button lights red as an alert. Press the Mute button again
to restore the output channel’s signal.
These controls are used to set the output levels of channels 1 to 6, allowing the
matching of the DSP 600 to the input levels of the devices chained in sequence.
Correctly setting these controls results in an improved S/N ratio. The digital output
gain control should be used when higher output levels are needed. Use the controls to
attenuate the output levels. It is not recom- mended to use the digital output gain
control for massive attenuation, since this would reduce the dynamic range of the D/A-
converters.
Label of input or output channels, the labels can be edited at the Config & Info
window.
