OUTPUT LEVEL CONTROLS
!
The ZTPRE features an output level control for each channel which sets the output voltage of the ZTPRE to match
the amplifier's input sensitivity. It is recommended for DECWARE amplifiers that have input level controls also known
as gain controls and also used as volume controls when no preamp is used, to have the output level of the ZTPRE at
full and experiment from there, whereas using the ZTPRE with non-DECWARE amplifiers it would be best to follow
!
this set up as your starting point:
Turn your amplifier ON and let it warm up a bit. While it warms up be sure your output level controls are turned all
!
the way down.
Turn on your source and raise the volume controls to the half way point. You will hear no sound yet, because the
output level controls are turned all the way down. Slowly raise each control one click at a time until the amps are
playing at your normal listening level. The ZTPRE output controls are now set. From this reference point you can
experiment with setting the output controls higher or lower and compensating with the master volume controls on the
front of the ZTPRE. Just go with whatever sounds the best. You are listening for dynamics, density, and a fullness to
!
the sound when you make these adjustments.
!
The output level controls come standard with ALL variations of the ZTPRE. They consist of 20 position gold contact
stepped attenuators using 1% precision metal film resistors with no leads and no circuit boards. There is no signal
! !
degradation as a result of these controls.
