Which iPods can I use with ProTrack?
You can use iPod 5G, 6G, and 7G Classics; iPod nano 2G, 3G, and 4G (nano-chromatic), and iPod Touch 2G.
What kinds of devices can I connect to its line inputs?
You can connect microphones, CD players, samplers, keyboards, or any other line-level device. ProTrack’s inputs can accept a 1/4" or XLR connection. (You can even connect a high-impedance instrument like a guitar, though in this case we recommend using a preamp to lower the signal's impedance for the recorder.)
Can I record if I don't have external microphones?
Yes, ProTrack's built-in condenser microphones are great for stereo recording.
How is ProTrack powered?
ProTrack can be powered by 4 non-rechargeable AAA batteries or you can connect it to a power source using the included AC adapter. (You cannot use rechargeable batteries with ProTrack.) You may also use an external battery pack, but its polarity must be "center positive." See the "Technical Specifications" in the Quickstart Guide for more information about external battery pack requirements.
Does ProTrack record in mono or stereo?
Either! Simply flip the RECORD MODE switch on the side panel to "Mono" or "Stereo."
How do I know when my batteries are low?
When the internal batteries in ProTrack start getting low, the two left LEDs on the ProTrack meters (lowest green Left LED and lowest green Right LED) will start flashing approximately every two seconds as a low battery indicator. The remainder of the higher LEDs on the meters will continue to indicate signal level as normal. This has no relationship to charge level on the iPod and only indicates the battery level of the ProTrack batteries.
Can I charge my iPod in ProTrack?
Yes, as long as you are using the included external power supply or an external battery pack. Don't forget to switch the “iPod Charge On/Off” switch to on.
Can I charge my iPod using ProTrack running on batteries?
No. This is because charging your iPod would eat up almost all of the batteries' power in a single charge.
I am planning to purchase an iPod for use with ProTrack. Do you have any recommendations?
There are two points to consider when selecting an iPod for use with ProTrack: how long you need to record and whether you'll be using the built-in mics or external audio sources (mic or line).
Hard disk-based iPods such in the Classic series can store hours upon hours of recordings, but run down their charge significantly quicker than the flash-based iPods, such as those in the nano family. For extremely long recordings, you'll want to have access to wall power so you can recharge your iPod between recordings.
Hard-drive iPods also make more operational noise because they have moving parts, whereas a solid-state flash unit does not. Since the built-in microphones are in close proximity to the iPod, we recommend flash-based iPods for the lowest-noise recordings using the on-board mics. When using external microphones or line-level sources, the hard-drive noise is not a concern.
Alesis does not recommend using iPod Classic 7G with ProTrack's on-board microphones due to its level of operational noise.
