audison AF C4DAF companion amplifiers are designed to add powerful amplifier channels to AF bit processor amplifiers. A plug and play signal input harness is included to make connection to AF bit amplifiers straightforward. AF companion amplifiers are also perfect for use with systems controlled and managed by a standalone bit processor, such as a bit One HD Virtuoso. AF companions have a straight wire architecture, without analog preamp functions such as crossover
AF companion amplifiers are designed to add powerful amplifier channels to AF bit processor amplifiers. A plug-and-play signal input harness is included to make connection to AF bit amplifiers straightforward. AF companion amplifiers are also perfect for use with systems controlled and managed by a standalone bit processor, such as a bit One HD Virtuoso. AF companions have a “straight wire” architecture, without analog preamp functions such as crossover filtering, and are intended for use with external processors. AF M4D boasts four high-fidelity amplified channels 90W x 4 @4?*, 150W x 4 @2?* with the audiophile sound of the latest generation Audison D-Class technology. Higher switching frequencies, steeper filtering, and higher-tolerance components deliver sound above and beyond the expectation of Class D – in an amazingly compact package! The audio band is extended up to 40 kHz earning the coveted High-Resolution certification. Bridging channel pairs results in 300W x 2 @4?*, guaranteeing flexible and powerful performance.
*Output Continuous Power (RMS) @14.4 VDC, 1% THD, all channels driven.
*Output Continuous Power (RMS) @14.4 VDC, 1% THD, all channels driven.

Great as a ‘pantry’ item for making a meal without previous planning.
Flavor Name: Variety Pack
Because of limited mobility, I never know who will do my grocery shopping and meal preparation. In other words, I can only count on having vegetables half of the time. I love adding this as a side dish or mixing it in with an entree. They work well cold or thrown into a hot dish. My favorites are the ‘riced’ cauliflower & the artichoke. I love the taste of the asperagus but found my body produced an even stronger aroma (if you know what I mean about asperagus eating) in this, possibly, more intense format. Very Satisfying all around. Great substitue for something more starchy.

Crisp but with sour taste from lactic acid.
Flavor Name: Variety Pack
Thought it might be nice to have pantry stable veggies. However, they have a noticeable sourness due to the lactic acid used as preservative. This is probably necessary to avoid heating/cooking as is done with canned vegetables. They are much crispier than canned vegetables.
The sourness might be fine in some dishes or to some tastes.
