User manual INDESIT WIL123S

[. . . ] Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. [. . . ] ρ Double Power mode (switches 4 and 8) When a low impedance connection is used, these switches specify the output of the amplifier. If the 280W {140W} setting is selected, input/output is enabled for both channels. If the 560W {280W} setting is selected, the output from the amplifier will be doubled, but input/ output will be disabled for channels B and D. ρ 70V/100V (switches 2 and 6) When a high impedance connection is used, these switches specify the maximum output voltage (Vrms) of the amplifier. WIL123S Owner’s Manual UNIT ID PC  Switches 7 and 8 (START UP MODE) These specify the startup mode of the XMV. dIP Switches Setting RESUME Description The unit will start up normally. The internal memory will be initialized. For details on the INITIALIZE memory that will be initialized, refer to “Initializing the Internal Memory” (page 22). 11 Controls and Functions @3 [SPEAKERS] output connectors These are barrier strip type speaker output connectors. For details on how to make connections to a barrier strip, refer to the “Setup” section entitled “Connecting the speaker output connectors” (page 15). @4 [REMOTE] connector This is a Euroblock 3-pin connector that allows muting/ unmuting of all channels and power-on/standby to be controlled remotely. ρ Checking the device setup DIP switch settings Make sure that all of the rear panel’s device setup DIP switches are in the upward position. € If cables will be frequently connected and disconnected, as in the case of a portable installation, we recommend that you use ferrules with insulation sleeves. Use a ferrule whose conductor portion has an external diameter of 1. 6 mm or less, and a length of approximately 7 mm (such as the AI0, 5-6WH made by the Phoenix Contact corporation). Slotted screwdriver Terminal screw  Making settings for speaker output Use the rear panel [SPEAKERS] DIP switches to make the appropriate settings for the XMV’s speaker output. The method of connection will differ depending on whether you’re using a low impedance connection or a high impedance connection. Low-impedance connection Euroblock plug Tab 8Ω/4Ω High-impedance connection NOTE A slotted screwdriver with a blade width of about 3 millimeters is recommended. The explanation of the settings is divided into the following sections. ρ When using low impedance connections (page 14)  When using low impedance connections with Double Power mode (page 15)  When using high impedance connections (page 15) Since these settings can be made independently for channels A/B and channels C/D, you can use more than one of the above methods 3. Pull the cables (not too strongly) to confirm that they are securely connected. Bundle the cables and the Euroblock tab using the supplied cable tie. [. . . ] That can mean reduced output level and sound quality. Below we examine the merits and demerits of low-impedance and high-impedance connections in relation to transmission over significant distances. ρ High Impedance Even if the cable resistance reaches 8Ω due to an extended transmission distance, this is an amount that can be ignored relative to the impedance of the speaker system, meaning that transmission loss due to the cable will be insignificant, and thus will have little effect on the transmission efficiency of the electrical signal. Speaker transformer (1kΩ) Almost 100% Cable resistance = 8Ω 70V/100V Long distance  Low Impedance For short distances over which cable resistance is insignificant, low-impedance connection allows the power amp to be directly connected to the speaker system without the need for speaker transformers.
