User manual PIONEER S-1EX-QL

[. . . ] When using a graphic equalizer to emphasize loud sounds in the high-frequency range, do not use excessive amplifier volume. Do not try to force a low-powered amplifier to produce loud volumes of sound (the amplifier's harmonic distortion will be increased, and you may damage the tweeter). Screw two picture hooks or similar into the wall behind the speaker. Pass a chain or cord around the hooks and through the metal catch so that the speaker is stabilized (make sure to test that it supports the weight of the speaker). [. . . ] Use the supplied spike pads to avoid scratching the floor or other surface where the speaker is placed. These speaker terminals carry HAZARDOUS LIVE voltage. To prevent the risk of electric shock when connecting or disconnecting the speaker cables, disconnect the power cord before touching any D3-4-2-2-3_A_En uninsulated parts. 4 Insert and turn the supplied hex wrench until the spike protrudes from the base. Do this in turn for each spike, making sure all four corners are of even height and the speaker is stable and resting squarely on all four spikes. 1 Switch off the power to your amplifier. Grasp the cap knobs on the lower input terminals and rotate them to the left (counter-clockwise), insert the speaker cable wires into the holes in the terminal posts, then tighten the knobs to secure the short bar as well as the wires. You can also use banana plugs for this connection. To do so, you must first remove the caps from the terminal posts. 5 After the spike lengths are even, tighten the nuts to fix the spikes in place. 3 Connect the other ends of the cables to the amp's speaker output terminals (for more details, refer to your amp owner's manual). After connecting the plugs, pull lightly on the cables to make sure that the ends of the cables are securely connected to the terminals. Poor connections can create noise and interruptions in the sound. If the cables' wires happen to be pushed out of the terminals, allowing the wires to come into contact with each other, it places an excessive additional load on the amp. This may cause the amp to stop functioning, and may even damage the amp. When using a set of speakers connected to an amplifier, you won't be able to obtain the normal stereo effect if the polarity ( , ) of one of the speakers (left or right) is reversed. 3 Connect the matched pairs to the same speaker terminals on your amp (taking care not to get the polarity reversed). Make sure to use the same type of cable for the low-frequency and the same type for the high-frequency connections. Bi-amping is an even more powerful way of connecting your speakers. Just as with bi-wiring, the input terminal short bars are removed, but here the low-frequency terminals are connected to a separate, dedicated low-frequency amp, and the high-frequency terminals are connected to a dedicated high-frequency amp. Bi-wiring requires two cables for each speaker, one for high frequencies and one for low frequencies. Using separate cables for the high end and low end improves the sound. [. . . ] With normal use, wiping with a dry cloth should be sufficient to keep the cabinet clean. If necessary, clean with a cloth dipped in a neutral cleanser diluted five or six times with water, and wrung out well. Never use thinners, benzine, insecticide sprays or other chemicals on or near this unit since these will corrode the surfaces. 2 Lijn de gaten in het front uit met de uiteinden van de schroeven aan de voorkant van de luidspreker en duw het front stevig op zijn plaats.
