The MX8750 E-PROM contains the firmware program for the MX8750 digital crossover

signal processor. The firmware program electronically defines the digital signal processing

functions and capabilities of the MX8750.

Section 1 Read This First

The E-PROM is an integrated circuit and is subject to the same precautions one should take in handling any

integrated circuit and for working inside an AC powered electronic device. This means:

1. Do not handle the E-PROM by its pins.

2. Ensure you are at the same voltage potential as the MX8750 chassis by grounding yourself to the MX8750.

3. Disconnect the MX8750 from the AC power by unplugging the AC power cord.

4. Disconnect all input and output cables from the MX8750.

DANGER: Failure to follow these precautions can result in injury or death to you or damage to the equipment.

Section 2 Unpacking

Remove the E-PROM from its packaging only after you have prepared the MX8750 to install the E-PROM and

are ready to install it. Handle the E-PROM only by grasping the ends. Do not handle it by grasping the pins.

Section 3 Description

The new E-PROM will update and, in some cases, change the functions and parameters in the MX8750.

However, whatever configuration is stored in the MX8750 will be retained in its non-volatile memory. If you do

wish to save these settings as a backup measure, do a FILE/SAVE or FILE/SAVE AS in the MXware program.
