    1. INTRODUCTION Thank you for selecting the German Physiks PQS 402 for your audio system. It uses an array of two DDD drivers to cover all frequencies above 220Hz. The low frequencies are handled by a system using two 10 inch drivers combined with four 8 inch passive radiators. The Loreley is entirely handmade and is built and tested by highly skilled technicians at our factory in Germany.

    These tasks will be carried out by the supplying dealer who has received detailed training from German Physiks engineers. Many of the component parts are very heavy and personal injury could result if they are inappropriately lifted.

  • Page 6: Assembly Procedure

    Assembly Procedure 1. Place the left loudspeaker bottom plate on the floor in the position where the speaker is to be sited. Ensure that it is sitting squarely on all 5 support points and that it is level. 2. Identify the left lower module. This has the input terminals and level selectors on its rear face.
  • Page 7 Figure 5. Fitting Upper Module and Connection Cables 4. The next operation must be carried out by two people. You will need 8 of the black inter-cabinet connecting cables ready to hand. Identify the left loudspeaker upper module. Place this on top of the distance frame and ensure that it is properly seated.
  • Page 8 Figure 6. Top Plate Cable Connection 5. Identify the left loudspeaker top plate and fit one black and one red cable to each pair of sockets as shown in figure 6. Figure 7. Top Plate Adjusting Screws The top plate has 3 screws, marked X in figure 7, which will be used by the dealer to adjust the module stack for any variation in verticality.
  • Page 9 Figure 8. Fitting the DDD Tower and Top Plate 6. Identify the DDD tower. Referring to figure 8, carefully fit the base of the DDD tower, Y, over the locating disc on the bottom plate and ensure that it is sitting squarely. Take great care not to damage the front of the lower bass module with the DDD tower, as there is very little clearance between where the DDD tower fits and the bass module.

    4. CONNECTING YOUR LOUDSPEAKERS The German Physiks PQS-402 is a 2 way loudspeaker with separate input terminals for the low frequency and high frequency sections of the crossover. These drive the woofers and DDD drivers respectively and are labeled as such. Provision is also made to allow the output level of the low frequency and high frequency cross overs to be adjusted.

    5. LOUDSPEAKER BREAK IN Like all audiophile equipment, German Physiks loudspeakers require a break in period from new before they reach their optimum level of performance. The music used for the break in should be dynamic in order to properly exercise all the components of the loudspeaker.

  • Page 12: Loudspeaker Placement And Set-Up

    Before the loudspeakers can be set up, the break in procedure in section 5 must be completed. The German Physiks PQS-402 is an extremely high performance loudspeaker and optimum performance will only be achieved when set up by a trained technician. For this reason the supplying audio dealer will carry out the set-up for the customer.
  • Page 13 We do not recommend placing the loudspeakers closer than 1m from the side walls, as the early reflections will degrade the stereo image. Positioning the speakers too close to the side walls will also lead to an uneven bass response. Aim to find the position that provides the best defined and most realistic stereo image when you are seated at the listening position.
