Pioneer SI-245 FEATURES AND BENEFITS, TROUBLESHOOTING GUIDE

FEATURES AND BENEFITS

Real World Power

The SI-245 delivers 45 watts per channel at 8 Ohms and 70 watts per channel at

4 Ohms. You’ll get tremendous bass and dynamics from every pair of speakers

Transparent Sound

The audio circuitry of the SI-245 is constructed using the finest parts available;

including 1% metal film resistors, high quality capacitors, and oversized heat sinks.

All this attention to technical detail creates a sound that is clear and uncolored with

phenomenal imaging.

Freedom From Crosstalk

Each channel of the SI-245 is powered via its own independent power supply. This

increases the isolation between the two channels, and minimizes cross talk guaran-

teeing you absolute silence as the backdrop to your music.

Current For Reactive Loads

The high current design of the SI-245 assures that even unusual and reactive loads are

handled with aplomb (a massive toroidal transformer with two separate windings, one

for each of the independent power supplies, provides more than ample current

to your system).

Freedom from Fan Noise

The oversized heat sinks inside the SI-245 allow the amplifier to stay cool even when

operating into low impedance loads—without the noise of fan-cooled amplifiers.

Independent Level Controls

Each channel has its own independent level control enabling you to precisely

match the SI-245 to the rest of your system. The level controls also enable you to

limit the volume, preventing abuse of the system.

Lifetime Connections

The SI-245 features stereo inputs, cascade stereo outputs, and five-way binding

posts which are all gold plated to ensure perfect connections without corrosion for

years to come.

TROUBLESHOOTING GUIDE

When there is a problem consult this guide first. If the problem persists, or you

have additional questions, call your local Niles dealer or Niles Technical Support

at 1-800-289-4434. The most common problems relate to hook up. Call from

your telephone extension nearest the system.

SYMPTOM

No sound on one channel

No sound on both channels

Hum from the speakers

POSSIBLE CAUSES AND TEST PROCEDURE

Short circuit or loose wire at the speaker or amplifi-

er terminals. Check that the connections are secure

and that there are no loose strands of wire crossing

from the positive to the negative terminals at the

back of the amplifier and /or the speaker.

Short circuit or a break in the speaker wire. Dis-

connect the speaker wire at both ends, separate the

2 conductors at both ends and test with a meter for

a short circuit. If there is no short, connect the two

conductors at one end and test with a meter for

continuity.

Speaker is not working. Connect the speaker to a

channel that plays another speaker.

Audio cable to input is bad. Connect another cable

that is known to be good.

Audio cable to the main inputs is bad. Connect

another cable that is known to be good.

Hum may be caused by a ground loop between

two of the other components in the system. To test

for another ground loop, try reversing the AC plugs

of each of the components in the system.
