The Ei-Series power amplifier features sophisticated high-performance DSP with
control for the input and output routing, filter network, EQ, limiter, and time align-
ment delay. Follow these steps to navigate through the Ei-Series internal DSP

DSP Settings
Preset - Choose either Manual Mode, which provides access to the full set of
adjustable parameters, or from the four speaker
presets: 2 full range, Mono 2-way, Sub/Sat, or 2 subs.
I/O - The I/O screen adjusts the settings for how the inputs will be routed through
the DSP to the output connectors.
Stereo: Ch A Input -> Ch A Output & Ch B Input -> Ch B Output
Mono A+B dual: Ch A and Ch B inputs are mixed together, each level control
adjusts the corresponding output level
Mono A+B link: Ch A and Ch B inputs are mixed together, Ch A level control
adjusts both Ch A and Ch B output levels
Parallel A dual: Ch A input is sent to both Ch A and Ch B outputs, each level
control adjust the corresponding output level
Parallel A link: Ch A input is sent to both Ch A and Ch B outputs, CH A level con-
trol adjusts the output level for both channels.
Filter (Manual mode) - The filter section allows you to build you own crossover or
add speaker protection by stetting the
filters to remove the upper and lower limits of the audio bandwidth.
Filter Ch A - Press the Edit button to enter the filter parameters for channel A.
Filter Ch B - Press the Edit button to enter the filter parameters for channel B. If
the Ch A filter is On, then the Ch B filter
can be set to the same settings by choosing A= B
LPF Freq - Rotate the EDIT knob to adjust the low pass filter frequency.
LPF Slope - Rotate the EDIT knob to adjust the filter type and slope roll off in dB
per octave.
HPF Freq - Rotate the EDIT knob to adjust the high pass filter frequency.
HPF Slope - Rotate the EDIT knob to adjust the filter type and slope roll off in dB
