12. sh to use the amplifier for multi amping or purely as a power amplifier you should connect the pre out of your Kandy Integrated Amplifier pre amplifier or surround sound processor to the corresponding Straight Input The gain of the Kandy Power Amplifier is exactly the same as the power amplifier section of the Kandy Integrated Amplifier and therefore is ideal for Multi amping Bi amping Tri amping etc IMPORTANT NOTE For optimum performance it is recommended to use high quality inter connect cables such as ROKSAN HDC 02A high definition analogue Cable Trimmed Input Connections If you wish to use the amplifier for Multi channel A V directly connected to the Kandy DVD 5 1 Dolby Audio output or as a power amplifier in an installation requiring its output level to be trimmed down then the Trimmed Inputs should be used e g You should connect the Kandy DVD audio output to the corresponding Trimmed Input of the Kandy Power Amplifier The output of the Kandy Amplifier can then be trimmed down 7dB by using the Trimmers 7 8 amp 9 on the back panel IMPORTANT NOTE It is always better to use the Straight Inputs when there are no requirements for level adjustment Even when connected to the Kandy DVD 5 1 audio output it is generally not necessary to connect to the Trimmed inputs In most cases the surround speakers can be run from the Straight input and only when the centre channel speaker is noticeably different in output to the surround spea

14. t Carefully observe polarity ensuring that the RED speaker terminal is connected to the RED amplifier terminal and the BLACK speaker terminal to the BLACK amplifier terminal When all the channels are connected to their respective speakers the amplifier is ready for use IMPORTANT NOTE For optimum performance it is recommended to use high quality cables such as ROKSAN HDC 02S High Definition Loudspeaker Cable Many speaker cables such as the ROKSAN HDC 028 are directional Please observe this directionality DO NOT use a speaker cable with conductor size less than 16 AWG 1 6mm Diameter The Binding posts accept conductor sizes up to 12 AWG Multi Amping The Loudspeakers Set u If the Loudspeakers utilise more than one drive unit with individual input terminals for example a Tweeter and a Woofer then the loudspeaker performance will greatly benefit from Bi Amping Dedicating one amplifier to the Tweeter and another to the Woofer isolates them from each other hence reducing distortion and increasing reserved power Speakers work far better with most amplifiers when Multi Amped than using one yet more powerful amplifier Bi amplified Speakers IMPORTANT Speaker Drive Unit Links must be removed NOTE Kandy Integrated Amplifier amp MkII do not have pre out sockets for multi amping If the loudspeakers have more drive units you just add more 2 channel amplifiers and connect respectively
