(note that Configuration 2 is not strictly speaking a dual-section attenuator, since there is no
electronic section available. However, it behaves exactly like Configuration 1 without the
Electronic Attenuator option EA3, therefore for the sake of this document it is grouped into the
“Dual Attenuator” configuration)
Single Attenuator Configuration
You can tell which attenuator configuration you have by pressing the Attenuation key, which (in
most Modes) opens the Attenuation menu. If the first key in the Attenuation menu says Mech
Atten
, then you have the dual attenuator configuration. If the first key says Atten, then you have
the single attenuator configuration.
Dual Attenuator Single Attenuator
In the single attenuator configuration, you control the attenuation with a single control, as the
fixed stage has only two states. In the dual attenuator configuration, both stages have significant
range so you are given separate control of the mechanical and electronic attenuator stages.
When you have the dual attenuator configuration, you may still have only a single attenuator,
because unless option EA3 (the Electronic Attenuator option) is available, and you purchase it,
you will have only the mechanical attenuator.
(Mech) Atten
This key is labeled Mech Atten in dual attenuator models and Atten in single attenuator models. In
the dual attenuator configuration, this key only affects the mechanical attenuator.
This key lets you modify the attenuation applied to the RF input signal path. This value is
normally auto coupled to the Ref Level, the Internal Preamp Gain, any External Gain that is
entered, and the Max Mixer Level, as described in the table below.
