=== Fan Operation ===
The fan turns on when the signal level is high, rather than using a thermal detector. When the
input signal reaches about -10 dBV, the fan will turn on. <ref> [[Media:A1 PackLite Service Manual.pdf|A1 PackLite Service Manual]], page 49</ref>

=== Product Variants 120V 220V ===
The PackLiteTM A1 amplifier has been manufactured in two versions, a 120V version (product
code 039057) and a 220-240V version (product code 039058)<ref>[[A1_PackLite_Service_Manual.pdf|A1 PackLite Service Manual]]</ref>
Here is a photo of the 120V version.

AC power connector: Accommodates the supplied AC power cord to connect your amplifier to the appropriate AC (mains) outlet. Check the product label of your amplifier for the voltage rating: 120V or 230V.

=== Application Notes  ===
==== {{Model II}} with {{B2}} ====
[[Image:A1 Model II.png]]
Note: The Model II Power Stand processes the bass signal differently with a B2 compared to a B1. The LED on the A1 will hit red sooner. If you don't hear any clipping, then you're okay. However, if you hear clipping from the B2 connected to the A1, then you can use a 10 dB [[Pad|Pad]] to attenuate the signal from the Model II Power Stand to the A1. That's connection 2 (green line) in the diagram above.  Note: Most inline attenuation pads use XLR connectors so you may need to get some Tip-Ring-Sleeve to XLR adapters to make the connections.

:I have never claimed to have a full and complete understanding of the bass thing, so I've been doing some reading from a while back and ran across something from Hilmar that might help me understand how and why you can go from 1 B1 to 4 B1's and not hear a major difference from a vocal or acoustic guitar that really just goes down to 80hz or so.

Yes, that's correct. Fundamental frequencies of those instruments are not present below 80Hz. That is why you'll find 80Hz high-pass switches on so many mixers and microphones- it allows you to trash those unwanted frequencies. In a performance enviornment it halts the pickup of unwanted bass frequencies (instruments, HVAC units, crowd rumble) from bleeding into your mics.
