MX5000A Development System Manual
1 System Overview
The MX5000A Development System allows manufacturers to easily evaluate and prototype
system improvements by adding MaxxAudio psycho-acoustic processing to existing audio
systems. The MX5000A Development System contains the small MX5000A Prototype
Module as shown in Figure 1, with simple connections for analog stereo input and output.
The MX5000A Development System also includes a Telos USB to I2C emulator with a
sophisticated PC graphic user interface. It also can be used without any external controls by
using the on-board potentiometers as audio controls.

2 Input/Output and Power Connections
Connect Inputs, Outputs, Power and Ground as described below. Please see Figures 2 and
3 for additional illustrations.
Connect Inputs
• Three sets of stereo inputs are provided. Located on the bottom edge of the PCB,
these are labeled as LI1/RI1, LI2/RI2, and LI3/RI3. Each stereo pair uses a common
ground, labeled “G”, located between the left/right inputs.
• Connect stereo inputs and ground(s) as needed.
• All analog inputs support 4Vpp maximum input levels.
Connect Outputs
• Connect stereo outputs, labeled LO and RO, on the left side of the PCB. LO and RO
use a common ground labeled GND between the LO and RO connection points.
• Connect subwoofer output (labeled SUB) and ground (labeled GND) if needed.
• All analog output support 4Vpp maximum input levels.
Connect Power Supply and Ground
• Provide an external 5.0V DC and ground to the 5VIN and GND pins to the upper right
corner of the PCB. This needs to be a well regulated analog supply, since this voltage
is connected directly to the analog_Vcc of the device without additional regulation.
