UPGRADE: MANLEY SLAM! Digital Versions only 5/1/2003  
This document also applies to REPLACEMENT of an Anagram Technologies ADC Module 
which has failed due to high heat conditions.

PURPOSE: Update the Anagram Technologies ADC Module to Software Version 3 to speed up clock estimation routine.

Serial numbers for units that will benefit from this update are:

SLAM 000-005; 022-095, and 119-121 which had a factory-installed Digital I/O card installed before 5/1/2003. ANALOG ONLY UNITS ARE NOT AFFECTED. DIGITAL CARDS SHIPPED AFTER 5/1/2003 ALREADY HAVE VERSION 3 SOFTWARE UPDATE.  

or ANY unit with a "D" serial number suffix that the Anagram Technologies ADC Module has failed outright.

UPDATE KIT INCLUDES:

a)       ONE Anagram Technologies ADC Module Version 3

b)       Instructions and drawings for procedure

TOOLS REQUIRED:

a)       Phillips #1 screwdriver

b)       EITHER of the following: 7/32” Nut Driver, 5.5mm Nut Driver, Adjustable spanner, small pliers, or very strong fingers.

Anagram Technologies ADC Module REPLACEMENT PROCEDURE:

CAUTION!!  The Digital card is sensitive to static electricity. Make sure to handle the card properly by grounding yourself touching the chassis of the unit or other grounded equipment before handling any static sensitive devices.

1.        Turn off the SLAM!’s Outboard Power Supply. Leave unit to cool off for 5 minutes.

2.        Leave the power connector hooked up from the audio chassis to the PSU. Also, leave the AC mains power cord plugged into to the wall. This will keep the unit grounded to the wall so that static electricity will go to earth instead of going to harm to static sensitive devices.

3.       Again, make sure power is turned OFF at the Outboard Power Supply!

4.        Remove the 2 Phillips screws securing the top grill cover. Remove the top cover by sliding it out towards the back. Put cover and screws aside.

5.        Locate the green Digital board in the center of the SLAM! audio chassis. The Anagram Quantum module closest to the front panel is the one you will replace!! That is the ADC. The other one is the DAC module and it is not affected by this software update. See picture below:

6.        Remove the 4 phillips screws holding the digital card and disconnect the two 34 ribbon cables. Make note of the solder lug under the front left mounting screw and the ground wire attached to it. Move it aside for now.

7.        Lift up the green digital card and turn it upside down to remove the 4 nuts securing chip, as well as each nut’s plastic washer. Make sure you note how the hardware is installed. When you install the new module, you must put the plastic washers back in place the way they were! See below for an example of correct assembly.

8.        Pull the module out tightly with your hand. The module is mounted in a socket and should be very easy to remove.

9.        Note that the module has a key locator to determine proper orientation. One of the pins under the module is clipped. Make sure to place the new module in the correct position. The module will self-destruct if you do not orientate it in the correct position! Additionally, the stickers on the top will tell you which way the modules should face. Both the DAC and the ADC face the same way.

Refer to this drawing for module orientation and location:

10.     Now replace the plastic washers and nuts to re-secure the new Version 3 module to the PCB as shown in the example above.

11.     Plug the 34 way ribbon cables back into their sockets and screw the green digital card back onto the spacers, remembering to put the ground wire solder lug under the front left mounting screw.

12.     Put the top back onto the unit by sliding it into the side rails from the back and popping it into the front panel slot. Secure it with the two silver Phillips #1 countersunk screws.
