PLAN B analog blog

The Plan B Model 15 Rev.2 will begin shipping on May 6, 2007. The circuit is identical to 
previous releases with the addition of a new connector to support the 15A Expander. This is 
the only circuit change. To facilitate this the PCB had to be redesigned and while we were at it 
we reconfigured that assembly to mount parallel to the faceplate, taking the overall depth of 
the module from 4.25 inches to just over 1 inch thick. Go to the EAR Homepage or M15 
product page for a photo.

The new 15A Expander adds functionality to the M15 and a direct result of customer 
requests. It connects to the Rev.2 VCO via a dedicated I/O connector located on the back of 
the PCB. It can however be retrofitted to any Model 15's regardless of revision, although 
earlier releases (rev 1 - 1.6) will require point-to point connections. the 15A is only 4 HP 
wide and adds a PWM attenuation pot, a Soft/Hard Sync crossfade pot (which amplifies the 
M15 sync function up to x4 it's previous intensity), 3 three way transposition switch 
(configured octave up/none/octave down) and two additional 1V/oct VC inputs. The 15A will 
begin shipping at the end of May 2007 with a retail price of $70. 

May is a busy month for us. Along with these two product additions, look for the new the 
M28 and 28A to be released sometime before June 1.

PG:  Can do as soon as the faceplates arrive.  They are running about a two week cycle, and were submitted late last week.  In the meantime, I've uploaded the faceplate art (a sorry substitute, I know!).  Go to the files section and click on 15A Faceplate Art.

Hi Peter,
it sounds very interesting, can we please have a picture of the expander 
15a?
Thanks for your efforts

oh i really wish the oct switch could be the LFO switch
that would be super.  no use here really for the octave switch...

The octave switch is very useful, LFOs are enough in a system, I 
think....or easy to purchase somewhere.
The model 15 is too valuable as to use it like an LFO.
Just my 2 cents

for live noise making.... i would want it
not that the octave switch is entirely useless, just for what I do the 
'lfo switch' would be grand
