A good user manual

The rules should oblige the seller to give the purchaser an operating instrucion of Art Pro Channel, along with an item. The lack of an instruction or false information given to customer shall constitute grounds to apply for a complaint because of nonconformity of goods with the contract. In accordance with the law, a customer can receive an instruction in non-paper form; lately graphic and electronic forms of the manuals, as well as instructional videos have been majorly used. A necessary precondition for this is the unmistakable, legible character of an instruction.

What is an instruction?

The term originates from the Latin word „instructio”, which means organizing. Therefore, in an instruction of Art Pro Channel one could find a process description. An instruction's purpose is to teach, to ease the start-up and an item's use or performance of certain activities. An instruction is a compilation of information about an item/a service, it is a clue.

Unfortunately, only a few customers devote their time to read an instruction of Art Pro Channel. A good user manual introduces us to a number of additional functionalities of the purchased item, and also helps us to avoid the formation of most of the defects.

What should a perfect user manual contain?

First and foremost, an user manual of Art Pro Channel should contain:
- informations concerning technical data of Art Pro Channel
- name of the manufacturer and a year of construction of the Art Pro Channel item
- rules of operation, control and maintenance of the Art Pro Channel item
- safety signs and mark certificates which confirm compatibility with appropriate standards

Why don't we read the manuals?

Usually it results from the lack of time and certainty about functionalities of purchased items. Unfortunately, networking and start-up of Art Pro Channel alone are not enough. An instruction contains a number of clues concerning respective functionalities, safety rules, maintenance methods (what means should be used), eventual defects of Art Pro Channel, and methods of problem resolution. Eventually, when one still can't find the answer to his problems, he will be directed to the Art service. Lately animated manuals and instructional videos are quite popular among customers. These kinds of user manuals are effective; they assure that a customer will familiarize himself with the whole material, and won't skip complicated, technical information of Art Pro Channel.

Why one should read the manuals?

It is mostly in the manuals where we will find the details concerning construction and possibility of the Art Pro Channel item, and its use of respective accessory, as well as information concerning all the functions and facilities.

After a successful purchase of an item one should find a moment and get to know with every part of an instruction. Currently the manuals are carefully prearranged and translated, so they could be fully understood by its users. The manuals will serve as an informational aid.

    - 6 - Ov er view Why use an external processing channel? The best way to get a signal to tape is by using the shortest signal path. In most cases, the shortest path is as follo ws: mic to preamp to compressor to EQ to tape. (The signal doesn’t even go through a mixer!) This isn’t a new concept, but it has become more relevant with the availabil[...]

Another Note: Most dynamic microphones won’t be affe cted or damaged if they are plugged into the Pro Channel when phantom power is turned on (we haven’t run across any).

Use the Preamp Outp[...]

    - 12 - Attack Switch The Attack switch selects th e attack characteristics of both the tube and optical compressor circuits. The Fast position (in) allows the co mpressor to react quickly to fast-rising attacks. Note that the tube circu it has an inherently fa st response and can be aggressive on signals with quick transients , such as snare drums.[...]

While you can use the compressor to add gain to a signal, it is better to add gain before the compressor for the best signal to noise ratio. If you want to us e the compressor to add more gain, use the VU meter to monitor the Pro Channel’s output level, or use the me ter on your [...]

Plug a microphone directly into either input and set the Input and[...]
