USER MANUAL TP 92 THORENS

Tonearm and Pick-Up Cartridge Fig. 1 The tonearm counterweight has been removed for shipping. Screw the counterweight onto the rear end of the tonearm and adjust the tracking force. ➔ Page 13 The TP 92 tonearm can accommodate most pick-up cartridges with a distance of 12.5 mm (½ ”) between the mounting holes. To connect the pick-up cartridge, push the four colour- coded cartridge tags onto the cartridge pins. If the cartridge pins are not colour-coded, connect them as follows: R right channel (signal) ➔ red G right channel (earth) ➔ green L left channel (signal) ➔ white G left channel (earth) ➔ blue14 Tracking Force The tracking force can be adjusted by rotating the to- nearm counterweight (➔ Fig. 2). The closer the counter- weight is to the cartridge, the higher the tracking force. The tracking force can be set with the help of the sup- plied stylus balance. Lower the tonearm lift, move the tonearm out over the platter and carefully lower it until the stylus of the pick-up cartridge comes to rest on the stylus balance. The stylus guard must be removed for this procedure. Great care should be taken to avoid damaging the stylus. Note: Refer to the user manual of your pick-up car- tridge to determine the correct tracking force. Fig. 2 Do not move the ring that sits around the middle of the tonearm tube (➔ Fig. 1). It serves as a vibration damper and is effective only at its original position.15 Anti-Skating Force (Bias) The interaction of stylus friction and cartridge-bearing forces produces a force which pulls the tonearm to- wards the centre of the record (referred to as skating force). This force can be offset with the help of anti-skat- ing force, which, in the case of the TP 92, is produced by a magnet incorporated into the tonearm. The anti-skating force is factory-adjusted. If neces- sary, it can be readjusted with the help of an adjust- ment screw. ➔ Fig. 3 Turn the adjustment screw anti-clockwise to increase, and clockwise to decrease the anti-skating force. The white dot above the adjustment screw indicates the set- ting. The amount of anti-skating force required depends on the type of pick-up cartridge used. If you change the cartridge for a different type, use a test record to determine how much anti-skating force is required. Fig. 316 Further Tonearm Adjustments The tonearm headshell allows an overhang adjustment of ± 2,5 mm to be made. To adjust overhang, loosen the screw holding the headshell and move the headshell as required. ➔ Fig. 4 A screw at the rear of the tonearm allows a further over- hang adjustment of ±3 mm as well as an azimuth ad- justment of ±5°. The screw is recessed into the top of the bearing housing and can be loosened with a 2-mm hex key. ➔ Fig. 5 The vertical tracking angle (VTA) can be adjusted by raising or lowering the tonearm. ➔ Page 16 Take care not to over-tighten the screws after making adjustments. Fig. 4 Fig. 517 Further Tonearm Adjustments The vertical tracking angle (VTA) can be adjusted by raising or lowering the entire tonearm. Loosen the lock nut (➔ Fig. 6) on the underside of the turntable; then turn the adjustment ring above the base to raise or lower the tonearm as required. If the VTA is changed, the tonearm lift will need to be to be readjusted. Loosen the locking screw on the to- nearm lift with a 1.5-mm hex key and carefully raise or lower the entire lift. ➔ Fig. 7 The tonearm tube should be parallel to the platter surface. Small adjustments of the VTA or the tonearm lift height can have a large effect. After making any changes, you should therefore always check whether there is enough clearance (at least 1 mm) between the cartridge and the record (when the lift is engaged) and between the tonearm lift pad and the tonearm tube (when the lift is disengaged).
