Description
The bhi
ATT2
high level to low level audio converter is used to convert high level audio
signals to low level audio. The
ATT2
attenuator pad was designed for use with amateur
radio transceivers and receivers mainly for use with the bhi ParaPro EQ20 range of
audio DSP units, but can also be used with other audio equipment provided the
parameters of the audio equipment being connected are within the specification of the
ATT2
. The
ATT2
is a passive device which effectively enables a wider range of
AF/volume adjustment to be used on the radio equipment before the overload LED on
the bhi ParPro EQ20 unit comes on, making it less sensitive and easier to use. The
ATT2
accepts mono or stereo speaker level signals and will accept input levels up to 1
Watt (2.828 Volts p-p into an 8 Ohm Speaker) and will attenuate the audio down to line
level at around 1 Volt (line level at 10k Ohm).
Note:
This unit is just an attenuator pad is not an audio signal isolating device. Ensure
that the signal output source references the speaker to ground. If the radio equipment
output source has a balanced speaker drive i.e. Class D type amplifier through to class
H amplifier, then refer to bhi Ltd for further advice on using the ATT2 unit with this type
of equipment to avoid causing potential damage to your radio equipment
. In this instance
you may require a bhi GroundBreaker audio isolating unit.
