DryTHD+N
This
test
checks
Reflex
THD+N through the dry
signal
path.
1 . Apply
a
1kHZ signal at
-26dBV
to the
Reflex
Left
Input.
2.
Adjust the
scale on the distortion
analyzer
to
measure .025%
THD+N.
3. Verify
a
distortion
level
<0.02%
& >0.001% THD+N
at
the
Reflex Left
Output.
4. Connect
the
oscillator
output
to
the
Reflex Right
Input.
5.
Connect the
analyzer input
to
the Reflex
Right
Output.
6. Verify
a
distortion
level
<0.02%
&
>0.001% THD+N
at
the
Reflex
Right
Output.
Dry Frequency
Response
This
test
checks the frequency response of
Reflex
through
the dry
signal path
at
the
following
frequencies:
20kHz 3kKz
5kHz 20Hz
1
. Apply
a
-26dBV
signal
at
IkHZ with
the
analyzer
BANDWIDTH filters off
to
the
Reflex
Right Input.
2.
Set
the scale
on the
distortion meter
to
measure +4dBV.
3.
Use
the output
level
at the
Reflex Right
Output for
the OdB
reference
to
check frequency response.
4.
Verify
thatthe
signal
leveloutput is
within
+/-0.56dBof
the
reference
atthe
above
frequencies.
5.
Connect the oscillator
output to
the Reflex
Left
Input.
6.
Connect the
analyzer input
to
the
Reflex
Left
Output.
7.
Repeat the
previous
tests
verifying
levels
for
the Reflex Left
Output.

-26dBV
(
into
a
600Q load)
to
the
Reflex Left Input
2.
Set
the scale on the distortion
analyzer
to
measure
+5dBV
signal
level.
3. Verify
an
output
of

+/-1
.56dBV
at
the
Reflex
Left
Output.
4.
Connect the
oscillator
output to the
Reflex
Right Input.
5.
Connect the
