User manual ALCHEMIST PRODUCT 8 POWER

[. . . ] ALCHEMIST 8 PRODUCT EIGHT POWER I N S T RU C T I O N MANUAL POSITIONING The Product 8 Power Amplifier is a class A/B type device, and as such it will need to dissipate a little heat. It should therefore be placed on a flat surface with free space all around. [. . . ] This is done by connecting a XLR or RCA cable through one of the channel on the Product 8 Pre Amplifier `preamp output' to the bridged `preamp input' on one of the Product 8 Power Amplifier. Note that there is a bridging switch on the back of the Product 8 Power Amplifier. By pressing this switch, you are toggling between RCA and XLR connection. LOUDSPEAKER CONNECTION As with all connections ensure that the equipment is switched off before you attempt to connect any cables. LOUDSPEAKER OUTPUT The Product 8 Power Amplifier has a bi-wiring facility and will allow you to connect your loudspeaker cables to your loudspeakers via either a 4mm banana type plug, a spade or bare wire type connection. If you are using the bare wire method make sure that all the strands of cable are securely within the binding post before you switch on your amplifier. The Red terminal is for your positive (+) connection and the BLACK terminal is for your negative (-) connection. If you fail to observe this pattern your system may result in an `out of phase' condition, giving you poor results in sound quality. + RIGHT OUTPUT _ XLR BRIDGED INPUT RCA BRIDGED INPUT BRIDGING SWITCH RCA INPUT RIGHT LEFT BALANCED INPUT RIGHT LEFT _ LEFT OUTPUT + ALCHEMIST MAINS INPUT AC ONLY~ This unit has been factory set to operate at the voltage marked below: No user serviceable parts inside.

When amplifiers are given a power rating, this refers to the maximum output. [. . . ] Keep the box for any future transportation of your product.
