Introduction 

Thank  you  for  purchasing  a  Y-Not.  This  product  is  designed  to 
provide all of the features you need to switch one audio signal to two 
audio  outputs,  while  being  able  to  address  the  common  problems 
that  can  occur  in  a  two-amp  system.  The  Y-Not  features  a  high-
quality buffer, a phase inversion switch and an isolation transformer 
all in a compact package. 

The  Y-Not  can  be  controlled  by  its  front  panel  switches,  by  an 
external  footswitch,  or  by  an  external  MIDI  controller,  making  it 
adaptable to virtually any situation. 

In this revision of the Y-Not, some features have been added. The first 
is  MIDI  controlled  phase  inversion  on  the  B  output.  This  comes  in 
handy if you are using two channel switching amps at the same time. 
Different  channel  combinations  will  have  different  phase 
relationships,  and  the  ability  to  switch  phase  will  insure  that  each 
combination sounds good. 

There  is  also  now  a 

TRS  In

  switch.  This  switch  is  designed  to  work 

specifically  with  electric  guitars  that  have  piezo  pickups.  These 
guitars  typically  send  both  signals  over  one  TRS  (tip-ring-sleeve) 
cable.  Pressing  the 

TRS  In

  switch  will  allow  the  Y-Not  to  use  both 

signals, sending the tip to the A output and the ring to the B output. 
With this arrangement, you can use the Y-Not to select whether your 
magnetic  or  piezo  signal  is  active,  and  send  the  signals  to  separate 
amps.
