User manual PIONEER CS-V230

[. . . ] Do not sit or stand on the speaker, or let children play on the speaker. Do not put large or heavy objects on top of the speaker. Do not place magnetic objects such as screwdrivers or iron parts near the tweeter or midrange. Since the speakers use strong magnets, the objects may be attracted, causing injury or damaging the diaphragm. [. . . ] Adjust the speakers so that they are equidistant from their respective side walls to assure balanced sound. This speaker system is supported by three points (the front two legs, and the back spike located between the back two legs). 1 Set the spike bases in the positions where the points of the three spikes will strike when the speaker is set down. Always use the spike bases as shown, with the indented surface facing up to receive the spike point. Place the left and right speakers equal distances from your listening position for good stereo sound. Use speaker cords of the same length for each speaker. So far as possible, place the front left and front right speakers on the same plane as the TV screen. To achieve optimum surround sound, you should place the TV between the left and right speakers, with the speakers pointing at a 50 to 60 degree angle toward the listening position. If the room has a lot of reverberation, we recommend hanging heavy fabric on the walls, and/or putting a carpet on the floor to damp the sound. If you do not use the spike bases when placing the speakers, the spikes may cause damage to the floor. If you plan on using the spikes we highly recommend to use the spike bases. Store the short bars in a safe place for later use. The lower terminals are for the bass, and the upper terminals are for midrange and treble sounds. Connecting the cables with reversed polarity may degrade the tone seriously. This speaker does not include speaker cables used for connecting to an amplifier. 1 Switch off the power to your amplifier. 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. 3 Connect the other ends of the cables to the amp's speaker output terminals (for more details, refer to your amp instruction manual). 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 connect the speaker's terminals with a banana plug. When using a banana plug, be sure to remove the cap at the tip of the input terminal. [. . . ] So what sounds "normal" can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts. to establish a safe level: · Start your volume control at a low setting. Slowly increase the sound until you can hear it comfortably and clearly, and without distortion. [. . . ]
