1-1 GETTING ST ARTED 1-1 GETTING ST AR TED PLACEMENT OF THE 860 STEREO POWER AMPLIFIER Y our Boulder 860 Stereo Power Amplifier is designed to r educe interference from external magnetic and radio fields (RF). While placement is not critical, known magnetic fields should be avoided.
1-2 GETTING ST ARTED CONNECTING TO THE MAINS OUTLET Y our 860 Ster eo Power Amplifier is supplied with a mains cor d suitable for the location where it was purchased. It is constructed of a large enough wire gauge and a cable plug appropriate for the voltage you intend to use.
1-3 CONNECTING A BALANCED SOURCE T o fully realize the sonic potential of your 860 Stereo Power Amplifier , use balanced connections whenever possible. Balanced cables r educe interference from magnetic and RF sources to an absolute minimum. Connect your preamplifier or sour ce outputs to the inputs provided.
1-4 GETTING ST ARTED CONNECTING AN UNBALANCED SOURCE Although the input connectors are of the three-pin XLR type, an unbalanced sour ce is easily accommodated by using a special cable. This cable has an RCA phono type connector on the source end and a three- pin XLR connector to go to the input of the 860 Stereo Power Amplifier .
1-5 GETTING ST ARTED POLARITY Please note that the 860 Ster eo Power Amplifier conforms to the standard of Pin 2 as the high or ”hot” for the balanced inputs. The polarity of the 860 Stereo Power Amplifier is such that a positive- going transition at Pin 2 will produce a positive-going transition at the “+” output terminal.
2-1 OPERA TION POWERING UP W ith all your connections made, you are ready to listen to your Boulder 860 Stereo Power Amplifier . T o turn the amplifier on, pr ess the ST ANDBY button on the front panel. The amplifier will perform a warm up cycle and the indicator will alternate between red and amber for 45 seconds.
2-2 CLIP DETECTION Clipping of the waveform r esults when any amplifier is driven at too high a level. A clip detection circuit is included in the 860 Stereo Power Amplifier . The indicator will indicate clipping by momentarily turning from amber to red.
2-3 SHOR TED OUTPUT DETECTION If the output of the amplifier becomes shorted, the fr ont panel indicator will turn red and the amplifier will turn off the output stage for about three seconds, then very briefly try to turn on again. If the short still exists, this cycle will repeat until the short circuit is removed.
3-1 REMOTE CONTROL OPERA TION Operation of the Boulder 860 Stereo Power Amplifier by r emote control is possible when connected by a Boulderlink cable to other Boulder pr eamplifiers or CD players. When so connected, the 860 Stereo Power Amplifier will be turned on and off with the other component.
4-1 BOULDERLINK "DAISY CHAIN" TO ALL OTHER SLAVE UNITS BOULDER PRE- AMPLIFIER BOULDER POWER AMPLIFIER BOULDER POWER AMPLIFIER MASTER SLAVE SLAVE BOULDERLINK Boulderlink is a means of interconnecting most Boulder products so that their micropr ocessors can talk to each other and pass important information.
4-2 SETTING BOULDERLINK SWITCHES Every Boulderlink system must have one “MASTER” component, and only one component can be set to MASTER. This is usually the preamplifier . Power amplifiers and other products not having a MASTER/SLA VE switch ar e not eligible to be “MASTER.
4-3 POWER UP VIA BOULDERLINK W ith each component connected together by a Boulderlink cable, and individually connected to the mains, pressing the master ’s ST ANDBY pushbutton will initiate the turn on sequence of all components. The first time a master is powered up, it will search for any “slave” units connected to it.
4-4 BOULDERLINK MESSAGES Each component in the system can send a message to the preamplifier which is then shown on its display . This is particularly helpful in confirming the operating status of each power amplifier in a multiple amplifier system.

APPENDIX 5-3 NOTES.
Un punto importante, dopo l’acquisto del dispositivo (o anche prima di acquisto) è quello di leggere il manuale. Dobbiamo farlo per diversi motivi semplici:
Se non hai ancora comprato il Boulder 860 è un buon momento per familiarizzare con i dati di base del prodotto. Prime consultare le pagine iniziali del manuale d’uso, che si trova al di sopra. Dovresti trovare lì i dati tecnici più importanti del Boulder 860 - in questo modo è possibile verificare se l’apparecchio soddisfa le tue esigenze. Esplorando le pagine segenti del manuali d’uso Boulder 860 imparerai tutte le caratteristiche del prodotto e le informazioni sul suo funzionamento. Le informazioni sul Boulder 860 ti aiuteranno sicuramente a prendere una decisione relativa all’acquisto.
In una situazione in cui hai già il Boulder 860, ma non hai ancora letto il manuale d’uso, dovresti farlo per le ragioni sopra descritte. Saprai quindi se hai correttamente usato le funzioni disponibili, e se hai commesso errori che possono ridurre la durata di vita del Boulder 860.
Tuttavia, uno dei ruoli più importanti per l’utente svolti dal manuale d’uso è quello di aiutare a risolvere i problemi con il Boulder 860. Quasi sempre, ci troverai Troubleshooting, cioè i guasti più frequenti e malfunzionamenti del dispositivo Boulder 860 insieme con le istruzioni su come risolverli. Anche se non si riesci a risolvere il problema, il manuale d’uso ti mostrerà il percorso di ulteriori procedimenti – il contatto con il centro servizio clienti o il servizio più vicino.
