User manual INDESIT WIL123S

[. . . ] If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. [. . . ] For example if two 8Ω speakers are connected in parallel, the total impedance will be 4Ω. 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. 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. 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. ρ When using low impedance connections Depending on the impedance (4Ω or 8Ω) of the connected speakers, set the [SPEAKERS] DIP switches as follows. Switches 1–4 (channels C/D) Switches 5–8 (channels A/B) Setting NOTE Trim any excess part of the cable tie as necessary. Insert the Euroblock plug into the Analog input connector of the device. NOTE If you make settings for low impedance connections, the HPF will automatically be turned OFF. The XMV features a switch function between 8Ω and 4Ω to guarantee the output in case it is connected to a speaker with an impedance of 8Ω or higher. If you connect a speaker with an impedance of 8Ω or higher, set the [SPEAKERS] DIP switches to 8Ω. If you connect a speaker with an impedance of 4Ω or higher, but lower than 8Ω, set the [SPEAKERS] DIP switches to 4Ω. [. . . ] But as you can see in the series connection wiring diagram, if one speaker system fails the second speaker system will be affected as well. 10W 4Ω 10W 10W 10W 10W Failure No sound Total impedance = 8Ω 4Ω Interruption WIL123S Owner’s Manual 25 High-impedance and Low-impedance Connections Transmission Distance and Efficiency The cables that transmit electric signals have resistance. The resistance in short cables is small enough that it can be ignored, but as transmission distance and cable length increase, resistance can increase to the point that signal loss and degradation occur. Below we examine the merits and demerits of low-impedance and high-impedance connections in relation to transmission over significant distances. [. . . ]
