EASY LEVEL SETTINGS

The SF-500 ir equipped with individual level controls of the

MID and HIGH range6. Adjust the level control to the most

suitable acoustic! of your room.

COMPACT, EASY-TOOPERATE PANEL DESIGN

Panel desigtr and dimensions match Pioneer's famous UA

Series of amplifiers and tuners. All controls are located to

easy accessibility.

3. If you have another manufacturer's stereo amplifier or

receiver, construct your system according to the B-way

stereo system.

a. When using the pre-amplifier and main amplifier

sections independently, use the B-way (for 2-way, omit

the MID range).

BUILDING THE MULTI .AMP SYSTEM

CONNECTING THE PRE.AMPLI FIER

Connect the INPUT terminals of the SF-b00 to the output

terminals of the pre-amplifier. With a STEREO amplifier or

receiver, connect the SF-500 INPUT terminals to the output

terminals of the pre-amplifier section (PRE-AMP OI_)IIPUT).

The upper INPUT jack is to the LEFT channel, the lower to

the RIGHT channel. Always correctly connect the left

output to the left input and the right output to the right

input of both pre-amplifier and SF-500.

3-WAY SYSTEM

In assembling a 3-way system, you need 3 power amplifiers

(LOW range, MID range and HIGH range) and independent

sets of speakers to each range. If a STEREO amplifier or

receiver is used, only 2 power amplifiers are necessary.

1. Connect the SF-500 LOW terminals and the input

terminals of the LOW range power amplifier. With a

STEREO amplifier or receivei, use the input jacks of the

main amplifier section.

2. Connect the MID jacks and the input jacks of the MID

range power amplifier.

3. Connect the HIGH jacks and the input jacks of the HIGH

range power amplifier. The upper jacks on the SF-b00 go

to the LEFT channel, the lower to the RIGHT channel.

Always correctly connect the left and right channels of

the power amplifiers.

2.WAY SYSTEM

In assembling a 2-way system, you need 2 power amplifiers

(LOW range, HIGH range) and independent sets of speakers

to each range.

If a STEREO amplifier or receiver is used, only one power

amplifier is necessary.

1. Connect the SF-500 LOW jacks with the input jacks of

the LOW range power amplifier.

With a STEREO amplifier or a receiver, use the input

jacks of the main amplifier section.

2. Connect the HIGH jacks and the input jacks of the HIGH

range power amplifier.

EVEL HIGH (HIGH RANGE LEVEL CONTROLS}

Turning the knobs to the right increases the output level of

the HIGH range, turning them to the left decreases it.

The left-hand knob regulates the left channel, the right-hand

knob regulates the right channel.

VEL MID (MID RANGE LEVEL CONTROL)

Use these knobs to regulate the output level of the MID

range.

Operation is the same to the LEVEL HIGH knobs.

OPERATING THE MULTI .AMP SYSTEM

o Multi-amp systems have more controls than conventional

systems and require more careful adjustments. Perform-

ance varies considerably with the pre-amplifier, power

amplifiers and speakers used, as well as with the acoustics

of the room, and final adjustments 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 fully 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 halfway 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 acoustics 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.

Otherwise 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 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.
