AMPLUS™ 100 TEST PROCEDURES
8.3 Reference a dB meter to the input level.
8.4 Perform the 1kHz Gain test as listed
in Table 6.
9. Response Test;
Source Input to 4
Ω Speaker Outputs
9.1 Apply a 31.5mVrms, 1kHz signal to the
Channel 1 and 2 Source Inputs at J1.
9.2 Reference a dB meter to this output
level at the 4Ω Speaker Output at J6.
This is the reference level.
9.3 Perform the 50Hz, 100Hz, 5kHz, and
10kHz Response tests for both channels
as listed in Table 6.
10. Bass Performance Test
10.1 Set up the unit under test as listed in
the Test Setup Notes section.
10.2 Apply a 31.5mVrms, 1kHz signal to
the Signal Input jacks at J1.

7.5 The level should be 115Vrms ± 10.0V
with 1.0% + 2.0% THD for 220/ 240V
models.
Note: For the following tests, set up the
unit under test as listed in the Test Setup
Notes section.
Note: Place 4Ω, 100W load resistors
across the 4Ω Speaker Outputs at J6 pins
3 & 4, and 5 & 6.
Note: Move the Amp Mode switch (S6)
from the 70/100V Bridged position to the
2-Channel position. This will enable the
4Ω outputs at J6.
8. Gain Test;
Source Inputs to 4
Ω Speaker Outputs
8.1 Set up the unit under test as listed in
the Test Setup Notes section.
8.2 Apply a 31.5mVrms, 1kHz signal to the
Signal Inputs at J1.
