The left control of the 

Timbre Lock

®

 at each one of the 

Model 88

 monoblocks 

usually  gives  you  the  impression  of  changes  at  the  bass  articulation  and  attack, 
especially with high-efficiency loudspeakers. Turning its potentiometer counterclockwise 
(first  or  second  LED)  makes  the  overall  sound  drier  while  turning  it  clockwise  can 
appear to reduce impact, attack, and internal detail after the fifth LED. Between these 
two positions, you will soon realize the effects on the overall presentation until getting 
the  best  position  for  the  right  amount  of  warmth,  presence,  and  resolution.  You  could 
thus think of the left control as a "definition control". So, generally speaking, in a correct 

Timbre  Lock®

  setting,  this  will  ends  with  one  of  the  first  five  of  the  LEDs  turned  on. 

 
 

The right control of the 

Timbre Lock

®

 at each one of the 

Model 88

 monoblocks 

usually gives you the impression that it affects the overall smoothness and tone. Again, 
going counterclockwise the sound turns progressively lighter and drier and clockwise it 
becomes  softer  and  warmer.  Moving  this  position  away  from  the  ideal  setting  in  the 
clockwise direction will make the sound fuzzier and less rich, in the same way, moving it 
away  from  the  ideal  setting  in  the  counterclockwise  direction  it  will  make  it  bodyless, 
empty. Think of this control as "sound density". 

 
 

Besides the left/right potentiometers adjustments, that gives you a kind of a dial 

to  get  the  best  balance  between  warmer  (but  softer),  when  you  go  to  clockwise 
direction, and clearer (but drier), when you go counterclockwise, you can also get new 
nuances  changing  the  offset  between  the  two  adjustments,  that  is,  depending  the 
amount of LEDs positions you have between the left and right adjustments in a single 
monoblock. This affects different qualities simultaneously, the perceived final extent of 
the high frequencies against the mid-range attack, the mid-range brightness rather than 
too  much  internal  detail  and  transparency,  emotion  rather  than  extreme  resolution. 
Usually,  the  ideal  range  of  this  difference  goes  from  1  to  3  LEDs  (bigger  values  may 
interfere with the overall perception of the sound image) and selecting the appropriate 
difference  for  your  system  is  often  more  important  than  the  absolute  position  of  each 
one of the controls. 
 

In 

Model  88 

the  yellow  LEDs  define  the  preferred  starting  position  for  the 

adjustments. As it also has enough adjustment range to work with any brand of tubes 
and even to get more from aged tubes (you certainly will always get the most of it with 
these  amplifiers), 

Model  88

  has  red  LEDs  that  are  a  clear  indication  that  you  are 

approaching  dangerous  presets  regarding  your  tube's  life.  So,  they  should  never  be 
used as a preset position.  

 
We recommend that when you first turn on the amplifier, you adjust the 

Timbre 

Lock® 

after a few minutes and again after about 20 minutes of power on. You should 

first  try  to  familiarize  yourself  with  the  effects  of 

Timbre  Lock

®

  and  then  look  for  the
