User manual DALI EUPHONIA

[. . . ] DALI® recommends the use of spikes for floor-standing speakers to ensure the best possible acoustic connection between floor and speaker. Like any other mechanical system, a speaker needs to be "run in", so you can look forward to a gradual improvement in sound quality over the initial period. Unlike other mechanical systems, regular use will in fact extend your loudspeakers lifetime. They should be located so that the distance between them is equivalent to the distance from the speakers to the listening position. [. . . ] The red terminal (+) on the amplifier must be connected to the red terminal (+) on the speaker, and the black terminal (-) on the amplifier must be connected to the black terminal (-) on the speaker. dALI® recommends connection with DALI® connect plugs or spade plugs to ensure a perfect electrical connection and mechanical stability. In the following pages, we will describe the special conditions that occur when connecting with tri-wiring or bi-wiring, and connecting the AS2 subwoofer. Tri-wiring means that the bass, midrange and treble tone ranges are each fed through their own separate speaker cable. In the ultimate set-up, there is an amplifier to handle each range (tri-amping). tri-amping is the sophisticated consequence of multi-wiring in a multipath speaker , which allows the maximum benefit of the EUPHONIA MS5. Bi-amping - when separate amplifiers are used for the bass/midrange tone and treble ranges - provides even greater openness in the acoustic image and adds increased dynamics. For bi-wiring on the MS5, we recommend that the treble and midrange terminals are combined and the bass terminals are supplied separately. DALI® EUPHONIA speakers can, of course, be used with single-wiring. In this case, the enclosed cables should be used with three stripped parts that are fed down through the terminals, thus connecting the bass, midrange and tweeter terminals. DALI® recommends that EUPHONIA speakers are connected with bi-wiring as a minimum to ensure the best possible conditions for acoustic imaging. This keeps powerful currents from the bass signals away from the cables that carry the treble/midrange tone signals. Thanks to its active crossover network and numerous connection options, the AS2 provides further advantages such as stepless variable phase. The AS2 is connected to a line signal either via 'Left/Right Input', 'Mono Input' or 'LFE Input'. It is important that the level of the connected line signal is controlled together with the equipment's volume control. Connection to stereo signal with full frequency content If the subwoofer is connected to a pre-amplifier without a built-in crossover network of the same high quality as the AS2, we recommend that the subwoofer's 'Left/Right Inputs' are connected to a signal with full frequency content from a normal pre-amplifier output. The subwoofer's built-in crossover network takes care of the necessary filtering. Once the subwoofer's 'Left/Right Inputs' are connected to a stereo signal with full frequency content, there is access to a highpass filtered signal (without the deep tones) on the 'Left/Right Output' sockets. This signal is connected to the power amplifier for the main speakers, which thus does not need to handle the demanding deep tones. This will always result in the main speakers playing more cleanly and un-stressed. Connection to mono signal with full frequency content If the subwoofer is only to be connected to a single channel, e. When using two subwoofers in a stereo set-up, and you want to use the subwoofer's built-in crossover network, the 'Mono Input' must be used. [. . . ] Heat - The appliance should be situated away from heat sources such as radiators, heat registers, stoves, or other appliances that produce heat. Power Sources - The appliance should be connected to a power supply only of the type described in the operating instructions or as marked on the appliance. Power Cord Protection - Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed on or against them, paying particular attention to cords at plugs, convenience receptacles and the point where they exit from appliance. Non-use Periods - The power cord of the appliance should be unplugged from the outlet when left unused for a long period of time. [. . . ]
