A U D I O P H I L L E O 1 & 2 U S E R M A N U A L 1 Chapter Getting Started Introduction T hank you and congratulations for purchasing the PurePower VLN battery power supply. We designed these devices to be the easy to use and provide the lowest possible noise as well as best isolation from dirty USB power, giving you peace of mind and allowing you to focus on other aspects of improving your audio system.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L Box Contents The PurePower ships with the following items: One PurePower power supply. One 12 inch USB A-B Cable (for optionally daisy chaining the Audiophilleo1/2 USB connection through the PurePower). One 12 inch custom threaded barrel connector cable for the most reliable power connection between the PurePower and Audiophilleo1/2 Connections Figure 1 shows how to connect the PurePower and Audiophilleo1/2 together.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L through to the AP1/2 like an extension cable. It is not a hub and therefore the total USB cable run from Audiophilleo to PurePower to PC cannot be more than 5 meters without a repeater cable. b. Option 2: You may alternatively plug the AP1/2 USB port directly into the PC as shown in Figure 2. In this case nothing is plugged into the PurePower “AP USB” port. You are finished.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L Figure 1 Connections – Option1: Audiophilleo1/2 USB cable feeds through the PurePower 6
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L Figure 2 Connections – Option 2: Audiophilleo1/2 USB cable connected directly to PC 7
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L Figure 3 Insert the power cable into the Audiophilleo, then GENTLY screw it on, then push it fully in. Note that with newer units it is only necessary to gently thread the cable in. After that it is already fully pushed in.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L 2 Chapter PurePower user interface The PurePower includes a joystick and backlit LCD display to provide status information in a user-friendly way. The joystick supports five directions: LEFT, RIGHT, UP, DOWN, and CLICK. After powering up, the main screen is displayed. The interface is similar to that of the Audiophilleo2.
A U D I O P H I L L E O 1 & 2 PURE CHARGE LOW U S E R M A N U A L The top right screen shows PURE when the PurePower is physically disconnected from the “PC USB” power input through the use of relays. In this case there is no electrical connection between then “PC USB” port and the PurePower (except for feeding through to the “AP USB” port, of course). In this mode, very low noise power is being fed to the AP since. CHARGE is displayed when the PurePower is charging the internal battery.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L Note: If the PurePower malfunctions, it should restart automatically. If it ever becomes unresponsive, simply PUSH the joystick and hold for 8 seconds to reboot your unit. Note: After a period of non-use, the PurePower will automatically enter a low power state and the screen may be turned off. Simply plug or unplug a cable or use the joystick to restore the screen.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L main menu Settings Charging Start Now starts a charge cycle immediately. Stop Now stops charging. Display Sleep is the number of secinds the LCD backlight takes to turn off Advanced Playback. When TurnOff is checked, the LCD is powered off when the AP is playing music, minimizing noise. Auto Level is the mA above which the AP is considered on. Start Volt is the battery voltage below which charging is started.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L 3 Chapter Changing the battery O ne of the design requirements was to make the battery user replaceable. This gives you the peace of mind that the power supply can provide many years of service and is not limited by the lithium polymer battery life. Typical battery life is expected to be approximately 3 years. Battery change only requires a Phillips screw driver and the removal of 2 screws.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L 4 Chapter Firmware Update with Windows O ur devices are designed with modular firmware that is easily updated. Updates will be released based on feature requests and bug reports. Please let us know if you have any requests. We will try to include any reasonable requests in the next firmware update. Firmware upgrade is supported under Windows and MacOS. For MacOS please see chapter 5. For updates please check http://audiophilleo.com/support.aspx.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L every few seconds). Once the backlight starts to flash slowly you may continue to the next step. The PurePower is now in firmware upgrade mode. The Windows PC sees it as a USB serial port. Step 2: Driver installation. Note: Under 64 bit windows, you need to disable driver signing in order to install the device driver. This video is a nice summary for how to do this under Windows 8: http://www.youtube.com/watch?v=NM1MN8QZhnk.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L If a security message pops up, select yes. The “Computer Management” console windows will open. Left click “Device Manager”, double click “Ports (COM & LPT)”. This gives you a list of installed ports. You want the PurePower to show up as one of these ports.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L 3. To determine which port is the PurePower, unplug the PurePower and check which port disappears. Then re-plug the PurePower to check that the port once again reappears. If instead of a COM port you get an “unknown device” (or something similar), then this means that the computer did not recognize the PurePower as a serial port.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L disconnecting it from the computer and seeing which COM port disappears from the device manager. Then you can reconnect it to the computer and the COM port should re-appear. Step 3: Run Firmware Tool You are now ready to perform the upgrade. This is done by double clicking on the “updatePP” file in this unzipped folder.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L Please enter the number of the PurePower serial port and press Enter. In this example it is 18.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L The PurePower will reboot and the update procedure is finished.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L 5 Chapter Firmware Update with MacOS O ur devices are designed with modular firmware that is easily updated. Updates will be released based on feature requests and bug reports. Please let us know if you have any requests. We will try to include any reasonable requests in the next firmware update. Firmware upgrade is supported under Windows and MacOS. For Windows please see chapter 4. For updates please check http://audiophilleo.com/support.aspx.
A U D I O P H I L L E O 1 & 2 U S E R M A N U A L Step 2: Software installation. 1. Double click the firmware DMG image file you downloaded in order to mount it. You will see this window: 2. Double click on “CrossPack-AVR.pkg” and follow the installation instructions to the end. Note that this only needs to be done once per computer. Step 3: Run Firmware Tool You are now ready to perform the upgrade. This is done by double clicking on the “UpdatePurePower” file.

A U D I O P H I L L E O 1 & 2 U S E R M A N U A L 6 Chapter Specifications Noise PurePower output noise levels are below the noise floor of our test equipment. Because the PurePower enters ultra-low power modes during music playback, its controller electronics effectively contribute zero noise to the output feeding the Audiophilleo1/2, making the output noise that of the internal battery itself. Compatibility The PurePower needs to be plugged into a power source via the “PC USB” connector.
Dimensions: 3.5 x 2.8 x 0.85 in (89 x 75 x 21 mm) Weight: ~ 7 oz (200 g) Electrical USB Bus Power (“PC USB”): 0 to ~500mA, 4.3 to 5.5 volts. “AP POWER” output: up to ~500mA, current limited.
