Pro-Ject RPM 1 Carbon
Dear music lover,
thank you for purchasing a Pro-Ject Audio Systems record player.
In order to achieve maximum performance and reliability with this record player you should study these instructions
for use carefully.
!
Warning of a hazard for the user, the unit or possible misuse.
Important notice.
The record player is supplied without cartridge or with a factory fitted and adjusted cartridge Ortofon 2M
RED.
** The following
instructions for adjusting the cartridge are provided in case the cartridge is mounted
(turntable was supplied without cartridge) or is replaced by a different model at a later date.
During assembly and adjustment of the deck small parts could be lost if not carefully placed in a suitable
receptacle. Before starting assembly familiarize yourself with the parts listed above and correspondingly
numbered in the technical drawings above. Separately packed items are marked with an asterisk *.
Set-up
Make sure the surface you wish to use the turntable on is level (use a spirit level) before placing the turntable
on it.
After putting the motor unit in place, fit the drive belt (2) around the platter (3) and the smaller diameter part
of the motor pulley (1). Avoid getting sweat or grease on the belt as these will deteriorate the performance
and reduce the belt's lifespan. Use absorbent kitchen paper to remove any oil or grease from the outer edge of
the platter and the belt.
Remove the transport lock (16) from the tonearm. Store it in the original packaging so they are available for
any future transportation.
Cartridge downforce adjustment
The counterweight (4) supplied is suitable for cartridges weighing between 5 - 12g (counterweight no. 82).
Adjust the downforce prior to setting the anti-skating force.
Place counterweight (4) halfway along the counterweight support rod at rear of arm, being sure to have the
securing screw uppermost.
Remove the felt mat. With the power off, and the platter static, place the stylus pressure gauge onto the
platter. To set the recommended 18mN downforce (1mN = 0,1g / 0,1 Pond), place the tip of the stylus
exactly in-between the two points marked 15mN and 20mN.
If the stylus gauge becomes level, then the correct pressure has been achieved. However if the there is
insufficient or excessive pressure the gauge will either not move or tilt down.
To adjust the amount of pressure, carefully move the counterweight (4) along the support rod, until the stylus
pressure is sufficient to raise the pressure gauge to the level position. Moving the counterweight (4) away
from the cartridge will reduce pressure and towards will increase pressure.
Finally secure the counterweight (4) using hexagonal key provided.
Please note: It is advised to remove stylus tip from gauge whilst making adjustments to avoid damage
to stylus.
