Resumen del manual
If the LED continues to glow amber with no speakers connected contact your Arcam dealer. OPERATION BY REMOTE CONTROL (ALPHA 8 ONLY) ■ The Alpha 8 amplifier is not supplied with a remote control handset but is remote ready. The volume up and down functions can be operated by the remote control handsets supplied with all Arcam CD players. It may also be possible to operate this function if your CD player remote control handset has volume up/down buttons and uses the Philips RC-5 remote control protocol. ■ The Alpha 8 amplifier can also be muted by use of the ‘MUTE’ button on the remote control handsets supplied with the Alpha 7, 8 and 9 CD players. The POWER LED will glow amber in this case to indicate that the amplifier has been muted. Pressing the ‘MUTE’ button again, or either of the volume up/down buttons on your remote handset will cancel the MUTE function. Section C ALPHA 8P POWER AMPLIFIER The Alpha 8P power amplifier can be used in conjunction with an Alpha 7 or 8 integrated amplifier to bi-amplify loudspeakers that offer two sets of input connections i.e. are biwireable. The Alpha 8P can also be used with a preamplifier or an AV processor or amplifier with power amp out sockets. MAINS CONNECTIONS Connect up as per instructions for the Alpha 7 and 8 integrated amplifier. LOUDSPEAKER CONNECTIONS Connect up as per instructions for Alpha 7 and 8 integrated amplifier. CONNECTING TO YOUR SOURCE EQUIPMENT © PWR AMP IN - Connect to your pre-amplifier outputs or the PREAMP OUT sockets of a Delta 290 or Alpha 7, 8 or 9 amplifier. © MONO LINK- The Alpha 8P can be connected to provide two mono loudspeaker outputs from a single input. Using the U-link © supplied, connect the MONO LINK sockets © together. Utilising one Alpha 8P per loudspeaker in this manner will allow bi-amplifying of biwireable loudspeakers. This is particularly beneficial for top quality stereo installations with a separate pre-amplifier, or for the left, centre and right channel loudspeakers in a five speaker Dolby Pro Logic system. Contact your Arcam dealer for more detailed information. ■ Daisy Chain - The Alpha 8P is capable of driving further Alpha 8P amplifiers (or any other power amplifier), to drive more speakers (eg. those in other rooms or tri-amplified speakers etc). Connect the extra power amplifier inputs to the MONO LINK outputs © left to left, right to right. FRONT PANEL © SP2 - Selects or defeats the loudspeakers connected to the terminals marked SP2. The main pair SP1 are permanently connected. © HEADPHONES SOCKET - Accepts headphones rated between 8ohms and 2k ohms fitted with a 6.3mm stereo jack plug. If your headphones are fitted with a different plug contact your dealer for a suitable adaptor. ■ The headphone socket is always switched on, irrespective of the position of switch ©. ENGLISH © POWER - Switches the power on and off. © POWER LED - This will initially glow amber. After a few seconds, it will glow green. When the LED glows amber, the speakers are disconnected and an internal protection circuit is activated. ■ If this LED glows amber during normal use it may be due to the amplifier overheating or an output overload. Check the amplifier is properly ventilated. Switch the amplifier off and wait for 2-3 minutes before switching on again. If the LED continues to glow amber, switch the unit off, remove all the speaker cables and switch on again. If the LED goes to green on switch on then check the speaker and speaker cables for short circuits before reconnecting them. If the LED continues to glow amber with no speakers connected contact your Arcam dealer. Section D BI-WIRING/BI-AMPING INSTRUCTIONS Many modern loudspeakers are equipped with four connection terminals. This provides direct access to the high frequency and low frequency filter networks and associated drive units within the loudspeaker. Overall performance can be enhanced by making use of these separate connections. WARNING: Do not make any connections to your amplifier while it is switched on and connected to the mains supply. Please check all connections thoroughly before attempting to re-connect the mains power supply. Always ensure that the volume control on your amplifier is set to a minimum before switching on. BI-WIRING USING BOTH SETS OF CONNECTIONS ON AMP BI-WIRING Bi-wiring uses four conductors, one for each terminal, to enhance dramatically the performance of your loudspeakers. Bi-wiring eliminates the signal distortion arising from the low and high frequency currents interacting with one another within a single cable, as used in conventionally wired systems. HOW TO BI-WIRE YOUR LOUDSPEAKERS 1. Remove the shorting links from each of the red and black terminal pairs on the rear of your loudspeakers. 2. You will need two lengths of loudspeaker cable per loudspeaker (which may be joined at the amplifier end) or a suitably terminated cable set capable of being used for bi-wiring in one length. 3. Connect the cabl...
