Processing Features
The D Series amplifiers include a number of integrated processing features
which appear on the front panel LCD screen.

MODES

* Stereo : In this mode, Channel 1 input signal goes to Channel 1 output, and Channel 2 input signal goes to Channel 2 output.
* INPUT Y : In this mode, the Channel 1 input signal is sent to the Channel 1 and Channel 2 output. The Channel 2 input signal is ignored.
* BRIDGE : In this mode, the power of both amplifier channels are delivered into a single Mono 8 or 4 ohm load.

FEATURES

* HPF : This filter reduces unwanted, potential energy-robbing low-end frequencies. Setting an appropriate high-pass filter frequency also helps protect the loudspeaker from damage. In this MENU, you can set roll-off frequency which are 40, 50, 63, 80, 100, 125Hz.
* LPF : The roll-off frequency can be set to 6.3K, 8K, 10K, 16K, or 20KHz to prevent un wanted high frequencies from passing to the speaker system.
* PEQ, 8BAND : An 8 band parametric EQ: 100Hz, 200Hz, 400Hz, 800Hz, 1.6KHz, 3.15KHz, 6.3KHz, 12.5KHz. Adjustable Q value and gain for boost and cut. Adjustable Q range is 0.5 ~ 5 by 0.5 step. Adjustable gain range is +/-6dB by 1dB step. Fine tuning your system has never been easier.
* LIMITER : provides your amplifier and system with higher performance and better protection. There is just one parameter of THRESHOLD for easy set up. You can set the threshold level to 0dB, -3dB, -6dB, -12dB.
* DELAY : Total delay time is 20mS per channel. Adjustable step is that 0~3mS / 0.25mS step, 3~10mS / 1mS step and 10~20mS / 2mS step.
* X-OVER (INPUT Y MODE ONLY) : X-OVER system provides a variable state Linkwitz-Riley 24dB/oct filter allowing you to choose a point between 50Hz and 3.15KHz on 1/5th oct centers.The following points are 50Hz, 56Hz, 64Hz, 74Hz, 85Hz, 98Hz, 112Hz, 129Hz, 148Hz, 171Hz, 196Hz, 225Hz, 259Hz, 342Hz, 392Hz, 451Hz, 518Hz, 595Hz, 684Hz, 786Hz, 903Hz, 1.03KHz, 1.2KHz, 1.37KHz, 1.57KHz, 1.8KHz, 2.08KHz, 2.4KHz, 2.7KHz, 3.15KHz.
