Front Panel Controls
Play Mode and Battery Display – The PLAY MODE
button is used to switch the Power DAC into the
highest quality playback mode. When the battery
charger is plugged in, pressing the button disconnects
the battery charger internally. The blue LED above the
button turns on. When pressed again the LED goes
out and the charger is connected. A charge LED lights
to indicate current charging status. When the battery
charger is disconnected, the button turns the DAC on and off. When on, the LED is lit and the DAC will play from battery power.
When toggled off, no LEDs are lit and the DAC is off.
FULL CHARGE LED – This LED is lit when the charger is plugged in and the batteries are fully charged. This could take a day or two
depending on temperature, line voltage and battery age.
CHARGING LED – This LED indicates that the charger is plugged in and the batteries are being charged.
LOW BATTERY – This LED is really a fault indicator and will be lit if a battery has failed or if the battery has been run completely dead.
When the batteries are fully discharged during play, the DAC checks to see if a charger is attached. If the charger is plugged in, the
DAC simply switches over to the charger and continues playing while recharging the batteries. If not connected to a charger, the DAC
shuts down. When the batteries are run down, pressing the PLAY MODE button should result in a short duration of play and then the
DAC will shut down again. The LOW BATTERY LED will light only light if the charger is plugged in, and the batteries have failed.
If the batteries have failed, pressing the PLAY MODE button will not result in any play back. If you want to restore playback, removed
the batteries and plug in the charger. The DAC will now operate on the charger alone.
No Battery – When you rst plug in the charger, if both the FULL CHARGE and CHARGING LED are immediately lit, it indicates that
either no batteries are installed or one battery has failed or become unplugged. The DAC will play with no batteries just off the charger
without harm but the sound will not be optimum.
Power Failures – When the power to the charger fails or the charger is disconnected while the DAC is playing on battery power, the
DAC continues to play without any problem. When the power to the charger fails or the charger is disconnected while the DAC is
playing in the normal charge mode, the CHARGE LED goes out and the DAC stops playing. When the power is restored, the DAC
continues playing without any problem.
Rear Panel Details
Option Switch – There is toggle switch , marked Option ON. This is a feature, which changes the Digital lter options. The normal position
is down. An alternate lter is engaged when turned up. The switch can also be toggled to reset a special lter installed via a CD.
The inputs are listed in order from lowest priority to highest priority for the automatic switching. This means that a when a higher priority
source is played, it interrupts the lower priority source. So put your background music on a low priority and your important sources
on higher priority inputs.
Toslink – Although this format has the lowest bandwidth, it is one of the more common outputs on low-end products. It also offers ground
isolation between products and noise immunity over long runs.
Coaxial – A good input for short runs and lower frequencies.
MSB Network – A CAT-5 input is for use with other MSB products.
Balanced digital – The AES/EBU Professional input is the preferred input. The balanced nature of this input allows great cable lengths
as well as total noise immunity.
