1. Headshell - Install cartridge here. When installing a cartridge, refer to the installation instructions supplied by the manufacturer of that cartridge. During installation, attach the stylus protector to guard the stylus tip from damage. Attach wires as follows:

White (L+) Left channel+

Blue (L-) Left channel -

Red (R+) Right channel+

20.S-Shaped Tone Arm

1. Tone Arm Lift - This elevates the tone arm above the record surface.

2. Anti-Skate Control - This applies inward force to the tone arm so it doesn't skip outward across the record due to the centrifugal force of the record spinning. Cartridge manufacturers usually specify the proper setting of this.

3. Counterweight - Adjustment creates the proper downward pressure of the stylus to the record. Attach now by sliding the counterweight onto the rear of the tone arm. Twist it lightly and it will screw onto the rear shaft of the tone arm.

1. Tone Arm Clamp and Rest - Use this rest for the tone arm and clamp it in position during transportation.

OPERATION

1. Push the power to on and the speed indicator and the strobe-illuminator will light up. the desired pitch is reached.

2. Insert target light for illumination the stylus.

3. Place a record on the turntable mat. When playing a 45rpm record with a large center hole; place the 45-rpm adapter on the centre spindle.

4. Set the rotation speed (33/45/78) to match the record.

5. Release the arm clamp.

6. Set the cueing lever to the up position.

7. Press the Start/Stop button and the turntable platter will start to rotate.

8. Move the tone arm over the desired groove.

9. Set the cueing lever to the down position, the tone arm will descend slowly onto the record and play begins.

10. Set the desired pitch adjusts range by depressing the buttons until Options are +/-8% or +/-12% or +/-20%.

11. Adjust the pitch to a desirable speed. During play, observe the strobe dots. If the strobe dots appear to the right, the pitch is slower than the rated speed. If they flow to the left, the rated speed. If the strobe dots appear stationary, which means the platter is in normal turntable speed, move the pitch control slider up or down to adjust the speed.

12. To suspend play, lift tone arm with cueing lever.

13. When play is finished, raise the cueing lever, move the tone arm to the armrest and secure the tone arm with the arm clamp.

14. Press the Start/Stop button to stop the platter rotating.

15. Push the power to off.

FUNCIONAMIENTO

DX-303/DX-505 turntables offer two signal output possibilities, PHONO and LINE. The output mode will be selected by means of the selector switch located at the rear side of the turntable.

If PHONO is selected the unit must be connected to a device equipped with Phono input RIAA. Most likely this will be a stereo mixer as seen at the draw below.

If LINE is selected the unit can be connected to almost all amplifying units. Just make sure that you connect it at the Line level input of the amplifier. This will be labelled as Line, CD, Tape or AUX.
