EMT 252 Upgrade Kit, Add Original EMT 250 Reverb Program To Your EMT 252. EN

For decades, audio professionals have been enamored with the sound of the EMT 250 reverb -- incredibly musical with just a hint of menacing rumble beneath.  The guys who developed that algorithm really did a brilliant job.  The model 252 reverb was a very fine rack unit unit, but early versions did not include the 250 reverb program.

Some studio engineers who loved the 250 were unhappy about this, with the sound of the 251.  EMT addressed this issue by issuing an upgrade kit that added the 250 reverb program to the 252. With the upgrade kit installed, the former SPC (space echo) program is replaced by the 250 reverb, with the exact same algorithm as the original 250.  The bandwidth is limited to 10.8 Khz with a soft roll-off, to match the 250.

Installation requires slight technical ability, but is not difficult.  After removing the digital PC board from the unit, one jumper wire is cut and four new ones are added.  The EPROM in the remote unit and the six PROM's in the mainframe are replaced with the new chips in our kit. These kits have been carefully tested and are 100% guaranteed.  We will gladly answer questions and provide phone and email support to buyers.

These kits are somewhat expensive because the 6 non-eraseable PROMs are obsolete and very costly, with a high reject rate. After production, each kit is tested in an actual EMT 252. It's expensive and time consuming for us to produce and test these kits.
