Quick Start List for Stand-Alone
2-7 Operation
Evaluation module preparations
7) To allow the module SE/BTL control input to switch the amplifier IC
between single ended (SE) and bridge-tied load (BTL) output modes, set
output mode jumper SE/BTL to
OFF. To keep the module amplifier IC in
the single-ended output mode regardless of the control input state, set
jumper SE/BTL to
ON.
8) To allow the module HP/LINE control input to switch the amplifier IC
between the HP pins and the LINE pins as the signal inputs, set the input
mode jumper HP/LINE to
OFF. To keep the amplifier IC in the HP input
mode regardless of the control input state, set jumper HP/LINE to ON.
9) To enable bass boost, set BBENABLE to ON. To disable bass boost, set
BBENABLE to
OFF.
10) To select the onboard active or passive filter, set the FILTER SELECT
jumper to ACT for the active filter or to PAS for the passive filter.
11) To allow the amplifier IC to switch from the LINE inputs to the HP inputs
when the output switches from BTL output mode to SE output mode and
vice versa, set jumper HP–SE to
ON. To allow the inputs and output modes
to switch independently, set jumper HP–SE to OFF. Connect control lines
to the various module control input pins as needed:
a) SE/BTL: A high selects the single-ended (SE) output mode; a low or
float selects the bridge-tied load (BTL) output mode.
b) HP/LINE: A high selects the LHP and RHP inputs; a low or float selects
the LLINE and RLINE inputs.
c) SHUTDOWN: A low shuts down the amplifier IC on the module; a high
or float allows normal operation.
EVM module controls
12) The EVM VOLUME potentiometer controls the volume of the platform
OUT+/– outputs. Turn this control clockwise to increase the volume.
13) The EVM BUFFGAIN potentiometer controls the volume to both the
platform OUT+/– outputs and the EVM LDOCK/RDOCK output
terminals. Turn this control clockwise to increase the volume.
14) The EVM BB ATT potentiometer controls the attenuation of the bass
boost. Turn this control clockwise to
decrease the bass boost attenuation.
15) The EVM ACTIVE and PASSIVE potentiometers control the cutoff
frequency for their respective filters. Turn these controls clockwise to
increase the filter cutoff frequency.
Power-up
16) Ensure that EVM potentiometers VOLUME, BUFFGAIN, and BB ATT are
set to their approximate mid points.
17) Verify correct voltage and input polarity and set the external power supply
to ON.
18) Adjust the signal source level as needed.
