Safety Review
Certain precautions should be taken when using electrical products. Please observe the
safety hints by reading the manual and obtaining qualified help if necessary to adhere to
the precautions. The power supply must be switched to the proper mains voltage.
Please check the red window on the power supply to verify the correct setting.
1. Always use a properly grounded power supply cord with this product. Please
do not defeat the ground pin on the mains plug. This connection provides earth to
the chassis and signal grounds inside the device for clean and quiet operation. The
"Internal jumpers and adjustments" page can help clear up a buzz problem if one
develops.
2. Avoid high temperature operation in equipment racks by providing air
circulation. The number one killer of electronic gear is HEAT. The life
expectancy of electrolytic capacitors (the usual casualty in a heat situation) goes
from 10 or 15 years to 10 or 15 weeks if the temperature inside the box is allowed
to rise beyond 140 degrees F. Vented rack panels may look like wasted space to
an interior decorator, but they look like beauty to a technician or equipment
designer! If the front panel is hot, it is roasting inside the box.
3. Avoid areas of high magnetic fields. The steel chassis of Master is designed to
shield the circuits from EMI and RFI (magnetic and radio interference). When
installing equipment in racks, it is prudent to put power amplifiers and large
power supplies at least several rack spaces, if not in a different rack, away from
equipment that deals with low level signals. Separation of high level and low level
equipment can pre-empt trouble caused by heat and EMI.
4. Care should be taken to avoid liquid spills around equipment. If a spill occurs,
please shut off the gear. A qualified technician should investigate accidents to
prevent further equipment damage or personnel hazards caused by spills.
5. Every attempt has been made by the designers to provide versatility in the set-
up and calibration of Master. As such, there ARE user serviceable jumpers and
calibrations inside. If one is uncomfortable with opening gear and changing
jumpers or making adjustments, please seek qualified help if necessary.
6. If adjustments or jumper changes are required, please unplug the power before
opening the top. Dropped screws or tools on a live circuit board can manifest
themselves as burn marks and smoked components. While we feel your pain,
(been there) subsequent damage is not covered by the warranty.
Dangerous Music Incorporated reserves the right to change the specifications or modify the designs of its
equipment. Sending in the registration card is our way of keeping in touch with users of our equipment
should this become necessary. Registration information is always kept confidential and never disclosed to
third parties for any reason. DMI wishes that the contents of this manual not be disclosed to third parties
without the consent of the designers.
