User manual TAG MCLAREN AUDIO PROTEUS F1-CA AVANTGARDE LOUDSPEAKER

[. . . ] As a result, the Proteus will easily integrate into your room and, when used in conjunction with F1-RLA loudspeakers, will create a perfectly integrated Home Theatre loudspeaker installation. 05 features features drive unit technology OFHC loudspeaker connection terminals single input connection Proteus is a three-way design using two 180 mm bass units, one 150 mm midrange unit and a 20 mm silk dome tweeter. The drive units have been optimised to maximise their performance within their respective operating bandwidths. A detailed description can be found in the technical data section at the end of this manual. high quality vibration isolated crossover The crossover is mechanically de-coupled from the sub-structure of the loudspeaker to prevent microphony in the components. The crossover network is mounted in the underside of the main loudspeaker enclosure in its own separate sub-enclosure. This no compromise crossover guarantees that sound energy is split between the drive units without affecting the purity of sound. [. . . ] Sound quality is dependent upon the placement of your loudspeakers in the listening room and the inherent acoustics of the room itself. You can place Proteus close to a TV set as it is magnetically shielded. The front of the Proteus should be aligned with, or placed slightly behind, the left and right speakers. Proteus has two crossover inputs reflecting the different acoustical requirements of a `Free Space' or `Floor' configuration. These two configurations are described in detail on the following pages. 'floor' configuration (in front of a screen or tv) If you want to locate Proteus on the floor, maybe in front of a tv or screen, then you should use the `floor' connection of the crossover. Connect the positive terminal marked `floor' to ensure you optimise the performance of your system. This engages a filter that compensates for the increase in low frequency output that is NEGATIVE COMMON generated by the loudspeaker's proximity to room boundaries and ensures optimum performance for this type of installation. before you start POSITIVE FLOOR loudspeaker connection room placement Proteus includes a Plinth Tilt Adjustment that allows you to tilt the loudspeaker upwards towards your listening position. Simply turn the adjustment wheel at the rear of the loudspeaker until the midrange's central axis points towards the ear height of the audience. 08 09 installation installation 'free-space' configuration (behind a projection screen or on a stand) If you want to place Proteus behind a sonically transparent screen and/or on stands, then you should use the `free space' input to the crossover. Connect the positive terminal marked `free space' to ensure you optimise the performance of your system. This engages a filter that compensates for the decrease in low frequency output that is generated by the loudspeaker's proximity to room boundaries and ensures optimum performance for this type of installation. For placement behind a transparent screen, it will be acoustically optimal if the Proteus midrange drive unit is located at approximately the same height as the midrange drive units of your main left and right loudspeakers. Proteus includes a Plinth Tilt Adjustment (see page 9 for details) that allows you to tilt the loudspeaker towards your listening position. POSITIVE NEGATIVE COMMON FREE-SPACE stereo installation A pair of Proteus loudspeakers can be used in a stereo installation. We would recommend that you adjust the angle of your Proteus' to reduce the protrusion of the rear foot to it's minimum position such that the acoustic output is directed towards the seated audience. We would also recommend that the `floor' connection (see page 9) is selected to provide an even tonal balance with respect to the room boundaries. 10 11 running in and warming up care and maintenance running in The performance of your Proteus will improve during the first 70 hours of operation. You may wish to play some programme material at a moderate level continuously for this period of time before seriously listening to your Proteus. Your loudspeaker will continue to improve over the next 100 hours of use. Every time you use your Proteus, the performance will improve until the components have reached their operating temperature which is typically achieved within 5 - 10 minutes of operation, depending upon the music material and volume level selected. cleaning In order to maintain the appearance of your Proteus, you can clean it as follows: Any grease or dirt on the enclosure may be removed with a soft, lint-free cloth moistened slightly with a mild solution of warm water and detergent or washing-up liquid. Take great care not to get any liquid inside the loudspeaker enclosure or on the drive unit diaphragms. [. . . ] These non-inductive resistors are manufactured from cermet mounted upon an alumina base offering extremely high peak voltage operation without compression. The series gain adjustment resistors commonly found in loudspeaker crossovers have been completely eliminated for best transparency. The tweeter level is matched to the midrange using an auto transformer that is wound on the same bobbin as used for the inductors. [. . . ]
