Troubleshooting - Samson DMS80 Manual Del Usuario

• No sound. Power LED is not lit.
Reinsert the power cord of the unit into an alternate outlet. If the
power outlet is good, unplug the DA80 from the outlet and check the
fuse. If the fuse is blown, replace it with a standard F3A miniature
fuse (5mm x 20mm) for 115V systems or T2A for 230V systems. If
the fuse blows again, do not replace with a larger ampere rated
fuse. Call Samson Customer Service for assistance at

• No sound, Power LED is lit.
1. Make sure all the cables sending audio signal to the DA80 are
secure and the corresponding switches are depressed to the on
position.
2. Volume level settings of equipment sending audio signal to the
DA80 should be checked and adjusted higher.
3. Make sure speaker wires are not shorted (direct connection of
the + and - terminal) causing the internal speaker protection cir-
cuitry to shut down the amplifier.
• Volume too low or very distorted.
Volume level setting or the sound card should be checked. Adjust
the sound card volume higher. Continue adjusting until the sound
level is balanced to the amplifier.
• The DMS80 becomes very hot and sound distorts.
The speakers are shorting. Recheck the wiring at the terminals or
additional speakers which may have dropped the load impedance
below 6 ohms. Speakers rated lower than 6 ohms will create a high
operational temperature and damage will occur to the DA80.
• Noise or static coming from the speakers continuously or inter-
mittently.
If your computer audio out is connected to the DA80 and your PC is
equipped with an 8 or 16-bit sound card and the sound playing has been
loaded from the hard disk, it is likely the noise is coming from the PC soft-
ware. Older sound cards and software sometimes deliver noisy perfor-
mance. Adjust the EQ to eliminate unwanted noise. Newer sound cards
and software which play sound from a CD ROM are not as likely to gen-
erate as much noise. Also check the DA80's performance by connecting
a home audio CD player to the AUX/CD input. If noise is no longer pre-
sent you can be certain the static was generated by the computer.
