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 251 reverb, though it is also a very fine unit, did not have this program.

Some studio engineers who loved the 250 missed having that program on the 251.  EMT received  complaints about the new model, and addressed them by issuing an upgrade kit that added the 250 reverb program to the 251.

With the upgrade kit installed, the former SPC (”space echo) button brings up the 250 reverb, which is the exact same algorithm as the original 250.  The “Cluster” control on the 250 adjusts pre-delay time from 0 to 80 ms or from 40-120 ms, depending on the position of the toggle switch.  The bandwidth is limited to 10.8 Khz with a soft roll-off, to match the 250.

With the upgrade installed, the original space echo program is not lost.  It can be obtained by pressing the D-REV button and pulling levers into their minimum positions.

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 six PROM’s are replaced and the board is reinstalled, and then one trimpot is adjusted for minimum noise.  These kits have been carefully tested and are 100% guaranteed.  We will gladly answer questions and provide phone and email support to buyers.
