4. MECHANICAL INSTALLATION

The DPX-100 mounts in a standard 19 inch equipment rack. The mounting screw threads vary with different rack manufactures and you should refer to your rack instructions for proper hardware. An oval head or flat head screw with a plastic countersink washer is pre- ferred to protect the finish of the DPX-100 under the screw.

This unit is housed in a rugged steel case and will tolerate moderate abuse. However, for road systems which may be dropped or otherwise subjected to extreme forces, we recommend some rear support for the chassis to prevent bending the front panel the front panel when these forces occur.

For installations where it is desirable to protect the front panel controls from tampering or accidental misadjustment, use the Ashly security cover. Installation is simple and does not require removal of the equipment from your rack. See your Ashly dealer for details.

5. EQ CONTROLS

5.1 EQ Boost/Cut

The individual equalization faders adjust the boost or cut at each filter frequency. By adjusting a com- bination of faders, an overall frequency response can be developed and the physical position of the faders will give an approximate visual indication of this response.

5.2 Gain

The gain control adjusts the overall gain of the equalizer when the EQ switch is “in”. It is generally used to compensate for level changes due to the equalization process, but can also allow the equalizer to adjust overall system level and gain structure. Overall gain with this control is from +6dB to -∞ .

5.3 Range

This switch selects the operating range of the individual equalization faders to either ±15dB or ±6dB. The ±15dB settings should be used when much equaliza- tion is needed. The ±6dB setting allows finer resolution on the fader settings.

5.4 HPF (Hi-Pass Filter)

The high-pass filter can be used to supplement the frequency response achieved by the bandpass filters. It’s function is to “roll off” low end response to eliminate subsonic interference like wind noise, floor rumble, and boomy microphone pops. The high-pass frequency is fixed at 20Hz with an 18dB/octave slope.

5.5 EQ In/Out

This switches out the boost/cut controls and EQ gain adjustments. This way, the effect of any equaliza- tion can be compared to a “flat” response. This switch does not defeat the high-pass filter.

5.6 Sig and Clip LEDs

The signal present LED comes on when a signal greater than -20dBu arrives at the EQ input. The clip LED indicates any EQ signal level exceeding +19dBu.
