AMPLUS™ 100 TEST PROCEDURES
1.4 The output level at J5 should be
+3.5dBr ± 1dB (balanced inputs), or
+13.5dBr ± 1dB (unbalanced inputs).
2. Gain Test;
Source Input to 70V/ 100V Speaker
Outputs
Note: Refer to Table 5. Source Input to 70/
100V Speaker Output test table for the
following tests.
2.1 Set up the unit as listed in the Test
Setup Notes section.
2.2 Apply a 31.5mVrms, 1kHz signal to the
Signal Input jacks at J1.
2.3 Measure the RMS Output Level using a
DMM. It should be as listed in Table 5.
3. Frequency Response Tests;
Source Input to 70/ 100V Speaker
Outputs
3.1 Set up the unit as listed in the test setup
notes section.
3.2 Reference a dB meter to the input level
and perform the Response 1kHz test as
listed in Table 5.
3.3 Reference a dB meter to the output
level. This is the reference level.
3.4 Perform the Response 60Hz and
Response 10kHz tests as listed in Table 5.
4. Total Harmonic Distortion (THD) Test;
Source Input to 70/ 100V Speaker
Output
4.1 Set up the unit under test as listed in
the Test Setup Notes section.
4.2 Apply a 31.5mVrms, 1kHz signal to both
Channel 1 and 2 Source Inputs and
measure the Total Harmonic Distortion at
the 70V/100V Speaker Outputs.
It should be 0.2% + 0.8%.
5. Noise Test;
Source Input to 70/100V Speaker
Outputs
5.1 Set up the unit under test as listed in
the Test Setup Notes section.
5.2 With no input signal applied, measure
the noise level in the bandwidth of 20Hz to
16kHz.
5.3 Noise level should be
-50dBV + 10.0dBV.
6. 70/ 100V Speaker Output Full Power
Test
6.1 Set up the unit under test as listed in
the Test Setup Notes section.
6.2 Apply a 280mVrms, 1kHz signal to both
Channel 1 and 2 Source Inputs.
6.3 Using a DMM, measure the output
level at the 70V/ 100V Speaker Outputs.
6.4 Output level should be 70Vrms
± 5.0V for 100/ 120V models.
6.5 Output level should be 100Vrms
± 7.0V for 220/ 240V models.
7. Power Amplifier Limiter Test
7.1 Set up the unit under test as listed in
the Test Setup Notes section.
7.2 Apply a 175mVrms (balanced inputs) or
95mVrms (unbalanced inputs),100Hz
signal to both Channel 1 and 2 Source
Inputs.
7.3 Using a DMM, measure the level at
the 70/ 100V Speaker Output jack.
7.4 The level should be 80Vrms ± 5.0V
with 1.0% + 2.0% THD for 100/ 120V
models.
