If a STEREO amplifier or rece

Perform- ance varies considerably with the pre-amplifier, power amplifiers and speakers used, as well as with the acoustics of the room, and final adjus

18、tments must be made while you are actually listening to the sound. o Before operating the SF-500, first check all connections correctly. When re-setting the selector switch, first turn off the power amplifiers or turn the volume fully down. 3. WAY SYSTEM 1. Turn the LEVEL MID and LEVEL HIGH knobs fu

19、lly to the left (i.e. set the levels to the lowest position). 2. Set the crossover frequency selector switch (located on the bottom of the SF-500) to 3 CH. 3. Turn the pre-amplifier output level knob fully down and turn on the power to all amplifiers. 4. Turn up the pre-amplifier output level halfwa

20、y and, also, the level controls on the SF-500. Play a record or tape. 5. Gradually turn up the pre-amplifier output level until the desired volume is attained. 6. Adjust the level controls on the SF-500 and the volume controls on all amplifiers until the sound quality is ideally suitable to the acou

21、stics of the room. PIONEETT 2. WAY SYSTEM 1. Check the crossover frequency best suited to your speakers and set the selector switch on the bottom of the SF-500 to 2 CH.600Hz or 2 CH.5kHz. NB. When setting the selector switch to 2 CH.5kHz, first check that nothing is connected to the MID jacks. Other

22、wise the MID range speaker may be damaged. 2. Proceed as explained in steps 3 - 6 for a 3-way system above. SPEAKER PHASING o Since the signals in multi-amp systems are separated by L2dB /oct. filters, correct phase adjustment of the speak- ers results in more natural sound. Where the MID range and

23、HIGH range power amplifiers are fitted with speaker phase selector switches, set these so that the sound is as natural as possible, during actual listening. If there are no switches on the polser amplifiers, try changing the connections to the speaker terminals. SPECIFICATIONS SEMICONDUCTORS Transis
