Warranty Service
Details concerning Warranty Service are spelled out in the Warranty section on page 15.
If you think your TAPCO S•8 has a problem, please do everything you can to confi rm it before calling for service. Doing so might save you from the deprivation of your monitor and the associated suffering.
These may sound obvious to you, but here are some things you can check. Read on.
Troubleshooting
No Power
•Our favorite question: Is it plugged in?
•Make sure line cord is securely seated in the line cord socket and plugged all the way into the AC outlet.
•Make sure the AC outlet is live (check with a tester or lamp).
•Is the POWER switch in the ON position?
•Is the power LED on the front panel illuminated? If not, make sure the AC outlet is live. If so, refer to “No Sound” below.
•If the power LED is not illuminated, and you are certain that the AC outlet is live, it is possible the fuse has blown.
To remove and replace the fuse:
1.Disconnect the power cord from the IEC socket.
2.Remove the fuse drawer by prying it open with a small screwdriver. It will slide all the way out.
No Sound
•Is the power LED on the front panel illuminated?
•Is the INPUT LEVEL control turned up?
•Is the signal source turned up? Make sure the signal level from the mixing console (or whatever device immediately precedes the studio monitor) is high enough to produce sound.
•If it’s a stereo pair, try switching them around. For example, if a left output is presumed dead, switch the left and right cords at the monitor end. If the problem switches sides, it’s not the monitor. It could be a bad cable, or no signal from the mixer.
Bad Sound
•Is the input connector plugged completely into the jack? If using a 1/4” TS or TRS plug, make sure it is plugged all the way in.
•Is it loud and distorted? Reduce the signal level at the mixer.
•If possible, listen to the signal source with headphones plugged into the preamp stage. If it sounds bad there, it’s not the monitor.
•Too much bass or not enough bass? Move around the room and see if the bass response changes. It’s possible your listening position coincides with a room mode where the low frequencies either become exaggerated or nulled. If so, try moving the monitors to a different position, or moving your listening position.
FUSE
3.Remove the fuse and replace it with an
115VAC unit: 1.6 amp
230VAC unit: 800 milliamp
4.Replace the fuse drawer by pushing it all the way back into the IEC socket.
If two fuses blow in a row, then something is very wrong. See the “Repair” section on the next page to fi nd out what to do.
Noise/Hum
•Check the signal cable between the mixer and the monitor. Make sure all connections are secure. These problems usually produce crackling noises or hum.
•If connecting an unbalanced output to the S•8 balanced input, make sure the shield is connected to the unbalanced ground and to pin 1 of the XLR (or the sleeve of the TRS jack).
•If a CATV cable is connected to the system, try disconnecting it. If the hum goes away, call your cable carrier to check for proper grounding of the cable.
