Hi,

I’m trying to tune the Plate Amp 2.1
Plate Amp 2.1 Firmware 4.6.415145.44
ACPWorkbench Version 2.21.14

Now I’m looking at the suggested configuration (see below)
But not able to find were I can do this within the ACPWorkbench Version 2.21.14 ?

How to Set Crossovers in ACPWorkbench 2.21.14

  1. Launch ACPWorkbench
    Connect your Up2Stream Plate Amp 2.1

The device should appear under the connection panel (USB or Wi-Fi)

  1. Go to the “Output EQ” Tab
    You’ll see Left Channel, Right Channel, and Subwoofer tabs at the top

Select one of the channels you want to tune

  1. Look for Crossover (HPF / LPF)
    In each channel’s panel (Left, Right, Sub), scroll down until you see:

HPF (High-Pass Filter)
LPF (Low-Pass Filter)

Each has settings for:

Option Description
Enable Check this to activate the filter
Type Choose filter shape (Linkwitz-Riley, Butterworth, etc.)
Freq Set the cutoff frequency (e.g., 2600 Hz)
Slope Choose dB/octave (e.g., 12, 24, 36, or 48 dB/oct)

  1. Example Setup for Tweeter (Right Channel)
    HPF: Enable
    Type: Linkwitz-Riley
    Freq: 2600 Hz
    Slope: 24 dB/oct
    LPF: Optional
    Type: Linkwitz-Riley
    Freq: 20,000 Hz
    Slope: 12 dB/oct or disabled

  2. Example Setup for Midwoofer (Left Channel)
    HPF: Enable
    Type: Linkwitz-Riley
    Freq: 100 Hz
    Slope: 24 dB/oct

LPF: Enable
Type: Linkwitz-Riley
Freq: 2600 Hz
Slope: 24 dB/oct

  1. Save Your Work
    Click “Save to Device” (bottom right)
    Then click “Load to Device” to apply the settings

Best,
Rain
