DSP Settings

Our engineers have painstakingly created a DSP controller for these monitors that lets you tailor the sound to your particular environment. The DSP settings provide precision adjustments that optimise the monitors for their position and mounting within the listening space.

Bass extension

The Core series monitors are designed to handle deep bass by themselves. And under normal conditions, the Bass extension switch should be set to “Full”. However, if you are integrating a Core Sub to extend the bass response even further, set the Bass extension to “HP”. This will engage a 4th order Linkwitz-Riley high pass filter at 80 Hz with time alignment that properly integrates the monitor with the Core Sub.

Bandwidth (Core Sub)

Use the LP setting when integrating the Core Sub to extend the LF response of a Core Monitor. This will engage a 4th order Linkwitz-Riley low pass filter at 80 Hz to integrate the Core Sub with the Core monitor.

Sound balance

The sound balance, or tilt filter, represents a refined way to affect the overall tone of the monitor (not applicable for the Core Sub). Depending on the room treatment and other factors, it may be necessary to make the monitor darker or brighter than the neutral setting. A dead sounding room with a great deal of treatment might need a brighter setting than a lively room with many reflective surfaces. Musical styles and program material may also affect the choice of sound balance as well as personal preference.

Sound Balance offers three settings:

  • Bright: 20 Hz -1,5 dB, 20 kHz +1,5 dB
  • Neutral
  • Dark: 20 Hz +1,5 dB, 20 kHz -1,5 dB

What this filter actually does is to tilt the entire spectrum by 1.5 dB at either end, using minimal phase filter to either brighten or darken the overall response. This minimal filter alters the tonality without inducing audible phase anomalies, thereby maximising the linearity of the monitor.

First Position Switch: Anechoic / Desk / Soffit

Depending upon where your Core monitors are positioned in your room, you can adjust the Core’s DSP to optimise for differing acoustics.

  • The “Anechoic” setting is used when the monitors are placed on monitor stands in rooms that have sufficient dampening treatment such as recording studios and film dubbing stages.
  • The “Desk” setting is used when the monitors are placed on a workstation or meter bridge of a mixing console (not applicable for Core Sub).
  • The “Soffit” setting is used when the monitors are mounted in properly designed wall soffits as part of an overall architectural acoustic design.

Second Position Switch: Free / Wall / Corner

Boundary filters controlled with the second Position switch are used to compensate for monitors that are placed close to walls or in corners where low-frequency room modes can be triggered by the monitor. The Core’s DSP can adjust the response to compensate for either a wall or corner placement.

  • If your monitors are placed further than 50 cm from any wall surface, use the “Free” setting.
  • If you have positioned your monitors within 50 cm of a wall the position switch should be set to “Wall”.
  • If the monitor is placed within 50 cm of a corner, set Position 2 to “Corner.”

These settings will help coping with anomalies created by reflections coming off the back and sidewalls, especially in the lower frequencies.
