the unit fails to latch when first turned on, quickly cycling power on the unit may yield the latch
condition.
The dAck! will sound great as soon as it is turned on. However, allowing a few minutes
for the circuit to stabilize will result in best performance. Since the circuit does not run hot, the
only major break-in will be in forming and conditioning capacitor dielectrics. This will occur
over the course of a couple weeks, after which the unit will give a slightly warmer, fuller sound.
Since it has been designed for utmost simplicity, the dAck! will only properly decode
44KHz, 16-bit stereo signals. If the input contains the wrong type of signal (for example, DTS
5.1 from a DVD), dAck! will still try to interpret the incorrect data, producing noise from its
audio outputs. In the case of multi-channel movies, dAck! will only work properly if the digital
source is configured for two-channel stereo.
Care and Maintenance
When the switch is in the down position, the batteries are being charged. An orange LED
indicator on the battery charger means that the dAck! is in bulk charge mode. Avoid interrupting
the bulk charge cycle if possible. When the light on the battery charger is green, the dAck!’s
battery cells are full or nearly full and are being float charged. Your dAck! will be happiest if it
is allowed to float charge most of the time. The charger light stays green when no load is
attached to it, showing that it is working properly. Keep the charger attached to the dAck! at all
times.
Important!
For best battery life, we recommend that you not use your
dAck! for more than 8 hours between recharge cycles, or
about 10 CDs. (For rapid charger version , <3 hours between
recharge cycles, or 3-4 CDs).
When dAck! is not being used, it should always be switched to
charge mode (switch in down position).
Do not forget to turn off your dAck! when not in use or you may
severely diminish its battery performance.†
More details on battery use can be found in Appendix B at the end of this manual.
Store the batteries in a fully charged state. If the charger is not connected to AC – for
example if you are going to store your dAck! for a long period of time – disconnect the charger
from the rear panel. The batteries will deteriorate if connected to a non-energized charger during
storage.
†Note: If you discover you have forgotten to turn your dAck! off for several hours, immediately switch it into
charge mode and allow it to float charge for at least 2 hours before use.
