referenced to 0.775 V, with no reference to
load impedance. This takes into account
the current audio scene where most equip-
ment has a low output source impedance
and a high input impedance.
Models 32A and 33A
Minimum Output Level
By design, the output level on the Model
32A and Model 33A Talent Amplifiers can-
not be set to fully “off.” While the output
level can be substantially attenuated, it
never can be set for full attenuation. This
implementation was selected to ensure
that talent personnel could never acciden-
tally be fully “isolated” from their program
or IFB source. There may be special cases
where full attenuation is desired. This
might be especially true with the Model
33A Talent Amplifier, where a mix of the
two IFB channels can be achieved. Provi-
sions on the Model 32A and Model 33A
circuit boards have been made to allow
this to be modified. In the standard design
a fixed resistor in series with one side of
the level potentiometer prevents full attenu-
ation. By replacing this resistor with a
“0 ohm” resistor or jumper strap, full at-
tenuation can be achieved. Contact the
factory for details.
