Carefully following the instructions in this manual will ensure that your loudspeaker system will give you many years of reliable and trouble free operation. For the latest information, help or advice, please contact your local PSI Audio representative or PSI Audio directly. Relec S.A.
• Do not operate or install this speaker near any kind of heat source. • Only operate this speaker with accessories specified by PSI Audio. • For maximum operating safety, the loudspeaker should be used with a three-wire AC power system. Two-wire operation may cause a potential hazard. 2.2 Service The loudspeaker contains no user-serviceable parts. Service must be performed by qualified personnel. The primary fuse must be replaced by exactly the same type and rating.
3.2 Front Panel Description Power ON LED (Green) Mains power is present and the speaker is ready to use. Limiter or Overheat or Standby LED (Red) Flashing of the led indicates that the internal limiter is working. If the LED works continuously, the amplifier is operating under overheated conditions and turns into standby mode. Suggestion for additional logo placement Anti-slippage stickers to be placed underneath the unit. 3.
4 Quick Start We recommend that you spend some time setting up your monitoring speaker system. Setting up naturally takes a certain amount of time. However, in case you need to get started quickly, please follow the quick set up guide. The rest of this manual will assist you in setting up your loudspeaker system and calibrate it according to your listening environment. • Check that the voltage value on the AC power selector is set correctly (according to your local AC power supply).
5.3 Audio Signal Input Connector The female XLR connector on the rear panel provides a balanced analogue input with the following wiring conventions : 1 = Chassis (Ground) 2 = + Hot 3 = - Cold When using the loudspeaker with unbalanced sources, the following wiring conventions may be used XLR Cable 1 2 3 Shield/Screen RCA/ Chinch 5.4 PSC Command principle PSC enables to control the standby mode of your loudspeakers through the signal cable.
When a loudspeaker is not used in free field mode, the « Roll Off » calibration must be applied. 6.3 Roll-Off practical view : Even at very low frequencies, a monitor is not really omni-directional, and it cannot be completely incorporated into a partition. Consequently, the acoustic pressure level will not be entirely doubled by the partition.
6.4 Mounting Please respect the instructions given in the “Technical Data Sheet” of each product. 6.5 Stereo Operation Position the loudspeakers so that the position between the listener, the left and right loudspeakers determine an equilateral triangle. The acoustic axis (see the Technical datasheet of your PSI audio monitor) should be at ear height or slightly higher. This is valid for any music listening mode (stereo, multichanel, etc..). 6.
• When commuting the first direct monitor or the second together with the subwoofer, the sound level hearing comparison allows a reliable and objective adjustment (± 0.5 dB). When adjusting the subwoofer level, the two systems should provide the same sound impression. Stereo & sub system calibration • The sub level being now calibrated, the signal from the first monitor should go through the sub and its Roll-Off adjusted @ -10dB Stereo & sub system in practice UANPA10 V4.
6.7 Multi channel 5+1 Operation Installation in multichannel covers a wide field of applications and different requirements have their own criteria. • Music & Home Cinema playback C+SUB R L 30° 30° 0° 11 LS RS 5+1 for music: Acoustical center Angle Height C L,R LS,RS SUB 0° ±30° ±100-120° ±10° 1.2m 1.2m ≥1.2m 0m Optimum subwoofer performance may be obtained by the use of two subwoofers • AV Applications (film & video) The standard Left / Right angle for film and TV is 45°.
7.2 Unbalanced to balanced operation It can give rise to problems and special care should be taken in cabling. 7.3 Poor audio quality Check the audio cabling to the speaker from the audio source, for poor wiring or broken connections. 7.4 Uneven frequency response In the case of uneven frequency response, please check the performance of the loudspeaker with a known reference source (i.e. your favourite CD).
