User manual AUDIO TECHNICA AT-LP1240

[. . . ] 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. 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. [. . . ] With its black dial toward the front, use a screwing motion to attach the counterweight to the arm extending back from the tone arm pivot [Figure 1, page 3, #22]; the counterweight will engage the spiral groove in the rear arm section and move forward. The Dust Cover The dust cover sits on top of the turntable without a hinge. To place the dust cover on the turntable, carefully lower it onto the turntable so that the Audio-Technica logo is facing the front of the unit. To remove the dust cover from the turntable, carefully lift straight up until the cover is clear of the unit. Setting Tone Arm Balance and Tracking Force To allow the cartridge to properly track in a record, the tone arm balance and tracking force must be carefully set to the cartridge manufacturer’s specifications. Failure to properly set up the tone arm assembly can cause damage to the cartridge stylus and/or records. (Note: Once the tone arm locking clamp has been released, take extreme care not to damage the stylus. While gently holding the headshell to stabilize the tone arm, release the tone arm locking clamp. Figure 3 – Headshell Assembling the Turntable Platter and Slip Mat 1. Carefully place the turntable platter on the center spindle, making certain the platter is fully seated on the spindle. figure 4 – Platter and Slip Mat 4 Initial Setup (continued) 5. While gently holding the headshell, carefully rotate the counterweight until the tone arm is horizontally balanced and hovers freely just above the platter without touching the platter surface. While holding the counterweight steady, and without any rotation, carefully rotate only the black stylus force gauge ring (which turns independently of the counterweight) until the “0” on the gauge ring lines up with the centerline marked along the top of the rear arm. Refer to the cartridge manufacturer’s specifications for recommended tracking force. Rotate the entire counter-weight counterclockwise without touching the black gauge ring, moving the counterweight forward, until the desired value on gauge ring lines up with the centerline marked on the rear arm. It may also be used to connect the turntable’s RCA output to other equipment, including: • a stereo/boombox equipped with a 3. To use either adapter cable, connect the turntable’s red and white RCA plugs to the cable adapter’s RCA jacks. Note: If connection is desired to a mono amplifier/speaker, make certain to use a stereo-to-mono adapter, available from your dealer or an electronic parts store. Inserting a mono plug in the stereo jack will disable one of the stereo channels. Other adapter cable configurations will be available from dealers and parts stores for connecting to devices needing different terminations. Connecting AC Power Cord Finally, after all other connections are made, attach the included AC power cord to the turntable; note that the small connector only goes in one way. Then connect the power cord’s plug to a convenient AC outlet. [. . . ] Make proper speed selection for record type being played with platter speed buttons. Depress Quartz button or return pitch adjust slider to center detent position to engage quartz lock. Verify that it is set for proper output to match mixer/amplifier input. Note: If using in USB or line mode, the pre-amp selector switch must be in the Line position. [. . . ]
