Loading a Custom Low-Pass Filter

To add a custom low-pass filter to your subwoofer you must first visit MartinLogan.com:

•www.martinlogan.com/balancedforce210/download

•www.martinlogan.com/balancedforce212/download

Download the appropriate file to match your main speakers. Save the custom low-pass file in the root directory of a USB flash drive. To assure a successful upload to your subwoofer we rec- ommend having no other files or folders on the flash drive—the subwoofer can only load one file at a time.

Insert the flash drive into the USB Input on the back of the subwoofer. The subwoofer will automatically find the file and load the custom low-pass filter. When a USB flash drive is connecting to the USB Input the USB Status light indicates the following information:

No color: Idle (no USB device currently connected).

Flashing Green: Reading USB flash drive.

Solid Green: Success. File found and loaded. Okay to remove USB flash drive.

Solid Red: Failed. No changes made. Cannot find file or flash drive not formatted using FAT32 file system (see FAQ and Troubleshooting).

Flashing Red: Failed. Cannot read drive due to electrical problem.

Updating Firmware

Please note, the subwoofer will load whichever firmware revi- sion is on the connected flash drive—even if the firmware revision on the flash drive is older than what is currently loaded on your subwoofer. To make sure you’re installing the latest firmware revi- sion check MartinLogan.com before updating your subwoofer:

•www.martinlogan.com/balancedforce210/download

•www.martinlogan.com/balancedforce212/download

To check which revision your subwoofer currently has installed, press the Custom Low-Pass button and hold it for 3 seconds. The Tone Sweep LED light will blink a number of times that is equal to

the current revision number (e.g. two blinks = revision 2 firmware).

Please note, updating the firmware should not erase settings for PBK (Perfect Bass Kit) and the Custom Low-Pass filter. A notice will be posted on our website alongside the firmware download if, for some unforeseen reason, a specific firmware revision must erase these settings—otherwise, these setting should still be in place after a firmware update.

1To update your subwoofer’s firmware you must first visit MartinLogan. (www.martinlogan.com/balancedforce210/ download or www.martinlogan.com/balancedforce212/ download) and download the latest firmware file for your subwoofer model. Save the firmware file in the root directory of a USB flash drive. To assure a successful upload to your subwoofer we recommend having no other files or folders on the flash drive—the subwoofer can only load one file at a time.

2Unplug the subwoofer from the AC outlet.

3Insert the flash drive into the USB Input on the back of the subwoofer.

4Reconnect the subwoofer to the AC outlet. The USB Status LED will continually blink red-green-red-green while the firm- ware is being updated—this blinking may pause momentarily during the update. Do not remove the flash drive until the LED stops blinking and shows a solid color for at least 5 seconds. See below.

When a USB flash drive is connecting to the USB Input the USB Status light indicates the following information:

No color: Idle (no USB device currently connected).

Blinking Green/Red: Reading USB flash drive.

Solid Green (for over 5 seconds): Success. File found and loaded. Okay to remove USB flash drive.

Solid Red (for over 5 seconds): Failed. No changes made. Cannot find file or flash drive not formatted using FAT32 file system (see FAQ and Troubleshooting).

Blinking Red: Failed. Cannot read drive due to electrical problem.
