Use the Maxx Control REST API to enable or disable channel EQ (eqenable) — bypass the whole equalizer for testing or mode changes while keeping filter settings intact.

Enable EQ for Multiple Channels

Enable the equalizer for multiple channels in a single request:

curl -X 'PUT' http://${IP}/rest-api/settings/channel/ \
-H 'Content-Type: application/json' \
-H 'token: f4005bf8507999192162d989d5a60823' \
-d '[

    "channel_id": 1,
    "dsp": {
      "eqenable": {
        "value": true
      }
    }
  },
  {
    "channel_id": 2,
    "dsp": {
      "eqenable": {
        "value": true
      }
    }
  },
  {
    "channel_id": 3,
    "dsp": {
      "eqenable": {
        "value": true
      }
    }
  }
]'
[
  {
    "channel_id": 1,
    "dsp": {
      "eqenable": {
        "value": true
      }
    }
  },
  {
    "channel_id": 2,
    "dsp": {
      "eqenable": {
        "value": true
      }

Single Channel EQ Control

Enable or disable EQ for a single channel:

curl -X 'PUT' http://${IP}/rest-api/settings/channel/1/dsp/eqenable \
-H 'Content-Type: application/json' \
-H 'token: f4005bf8507999192162d989d5a60823' \
-d '{
  "value": true
}'
curl -X 'PUT' http://${IP}/rest-api/settings/channel/1/dsp/eqenable \
-H 'Content-Type: application/json' \
-H 'token: f4005bf8507999192162d989d5a60823' \
-d '{
  "value": false
}'

Get EQ Enable State

Check if EQ is enabled for a channel:

curl -X 'GET' http://${IP}/rest-api/settings/channel/1/dsp/eqenable
{
  "value": true
}

Multizone Example

Example for controlling EQ across multiple zones (channels 1, 2, 3, 11, 12, 13):

curl -X 'PUT' http://${IP}/rest-api/settings/channel/ \
-H 'Content-Type: application/json' \
-H 'token: f4005bf8507999192162d989d5a60823' \
-d '[

  },
  {

    "dsp": {
      "eqenable": {
        "value": true
      }
    }
  },
  {
    "channel_id": 13,
    "dsp": {
      "eqenable": {
        "value": true
      }
    }
  }
]'
[
  {
    "channel_id": 1,
    "dsp": {
      "eqenable": {
        "value": true
      }
    }
  },
  {
    "channel_id": 2,
    "dsp": {
      "eqenable": {
        "value": true
      }
    }
  },
  {
    "channel_id": 3,
    "dsp": {
      "eqenable": {
        "value": true
      }
    }
  },
  {
    "channel_id": 11,
    "dsp": {
      "eqenable": {
        "value": true
      }
    }
  },
  {
    "channel_id": 12,
    "dsp": {
      "eqenable": {
        "value": true
      }
    }
  },
  {
    "channel_id": 13,
    "dsp": {
      "eqenable": {
        "value": true
      }
    }
  }
]

Note: When EQ is disabled, all equalizer settings (filters, gains, etc.) are bypassed, but the settings themselves are preserved. Re-enabling EQ will restore the previous equalizer configuration.
