Un buon manuale d’uso

Le regole impongono al rivenditore l'obbligo di fornire all'acquirente, insieme alle merci, il manuale d’uso Samson PL1602. La mancanza del manuale d’uso o le informazioni errate fornite al consumatore sono la base di una denuncia in caso di inosservanza del dispositivo con il contratto. Secondo la legge, l’inclusione del manuale d’uso in una forma diversa da quella cartacea è permessa, che viene spesso utilizzato recentemente, includendo una forma grafica o elettronica Samson PL1602 o video didattici per gli utenti. La condizione è il suo carattere leggibile e comprensibile.

Che cosa è il manuale d’uso?

La parola deriva dal latino "instructio", cioè organizzare. Così, il manuale d’uso Samson PL1602 descrive le fasi del procedimento. Lo scopo del manuale d’uso è istruire, facilitare lo avviamento, l'uso di attrezzature o l’esecuzione di determinate azioni. Il manuale è una raccolta di informazioni sull'oggetto/servizio, un suggerimento.

Purtroppo, pochi utenti prendono il tempo di leggere il manuale d’uso, e un buono manuale non solo permette di conoscere una serie di funzionalità aggiuntive del dispositivo acquistato, ma anche evitare la maggioranza dei guasti.

Quindi cosa dovrebbe contenere il manuale perfetto?

Innanzitutto, il manuale d’uso Samson PL1602 dovrebbe contenere:
- informazioni sui dati tecnici del dispositivo Samson PL1602
- nome del fabbricante e anno di fabbricazione Samson PL1602
- istruzioni per l'uso, la regolazione e la manutenzione delle attrezzature Samson PL1602
- segnaletica di sicurezza e certificati che confermano la conformità con le norme pertinenti

Perché non leggiamo i manuali d’uso?

Generalmente questo è dovuto alla mancanza di tempo e certezza per quanto riguarda la funzionalità specifica delle attrezzature acquistate. Purtroppo, la connessione e l’avvio Samson PL1602 non sono sufficienti. Questo manuale contiene una serie di linee guida per funzionalità specifiche, la sicurezza, metodi di manutenzione (anche i mezzi che dovrebbero essere usati), eventuali difetti Samson PL1602 e modi per risolvere i problemi più comuni durante l'uso. Infine, il manuale contiene le coordinate del servizio Samson in assenza dell'efficacia delle soluzioni proposte. Attualmente, i manuali d’uso sotto forma di animazioni interessanti e video didattici che sono migliori che la brochure suscitano un interesse considerevole. Questo tipo di manuale permette all'utente di visualizzare tutto il video didattico senza saltare le specifiche e complicate descrizioni tecniche Samson PL1602, come nel caso della versione cartacea.

Perché leggere il manuale d’uso?

Prima di tutto, contiene la risposta sulla struttura, le possibilità del dispositivo Samson PL1602, l'uso di vari accessori ed una serie di informazioni per sfruttare totalmente tutte le caratteristiche e servizi.

Dopo l'acquisto di successo di attrezzature/dispositivo, prendere un momento per familiarizzare con tutte le parti del manuale d'uso Samson PL1602. Attualmente, sono preparati con cura e tradotti per essere comprensibili non solo per gli utenti, ma per svolgere la loro funzione di base di informazioni e di aiuto.

The high and low frequency knobs provide 15 dB of cut or boost at 10 kHz and 100 Hz, respectively, with both utilizing a shelving curve. The EQ setting affects both the odd- and even-numbered channel inputs, althou[...]

    10 • Matched signals (i.e. the stereo left-right outputs of a keyboard, drum machine, tone generator, effects processor, CD player, or tape recorder), should always be connected to the PL 1602 ’ s paired odd/even channels (i.e. 1L/2R, 3L/4R, etc.). The channel Balance control will allow you to adjust the relative levels of the two inputs, and y[...]

    11 Setting up your PL 1602 is a simple procedure which takes only a few minutes: 1. Remove all packing materials (save them in case of need for future service) and decide where the unit is to be physically placed — it can be mounted in any standard 19" rack, requiring two rack spaces, or used on a tabletop. 2. Before even plugging the unit i[...]

    14 Gr ounding T echniques Hum and buzz are the biggest enemies you face when interconnecting a large number of different pieces of equipment to a central audio mixer. This is because each piece of equipment may operate at a marginally different voltage (this difference is called potential ) and, when two devices at slightly different potential are [...]

    15 Gr ounding T echniques If you ’ re using the PL 1602 in a fixed location such as a recording studio, you may want to invest the time and money into creating a star ground network . This is by far the best technique for avoiding grounding problems. It involves using a formidable ground source such as a cold water pipe or a copper spike driven i[...]

    16 Using the Balance Contr ol The final Main output of the PL 1602 is stereo — that is, there are two discrete Main output jacks, labeled “ left ” and “ right, ” which will normally be routed to two discrete speakers.* Because of this, you will usually be working with a stereo field that ranges from hard left to hard right. The PL 1602 pr[...]

    17 Using Equalization One of the most exciting aspects of using a mixer such as the PL 1602 is the ability to shape a sound, using a process called equalization . But there are few areas of sound engineering more misunderstood than equalization, and, just as good EQ can really help a sound, bad EQ can really hurt it, so read on... Every naturally o[...]

    18 Using Aux Sends and Retur ns The PL 1602 ’ s two Auxiliary sends allow you to combine the signal from multiple channels and send the resulting mix to external devices such as effects proces- sors. When an Aux send knob is at the “ 0 ” position, the signal is routed with unity gain (that is, no boost or attenuation). As it is turned clockwi[...]

    19 Using Channel Inser ts In addition to using Auxiliary sends and returns to access outboard devices, the PL 1602 also provides channel inserts for the first six input channels. These should be used when you want to affect just one input signal, as opposed to signal from several inputs — most often, this will be for dynamic processing purposes ([...]
