Installation manual

Quality control (QC) is a process which begins from the first designs entered into a
computer and then never ends.
Zed is continually striving to improve the products which we design and manufacture.
All our semiconductors are purchased from either the manufacturer direct or through
reputable distributors. Electrolytic capacitors which have the highest long term failure rate
of any component are chosen for their durability and sonic qualities.
Each and every product manufactured at Zed is tested using Audio Precision test
equipment. Software is written for each type of amplifier and then on final test the
amplifier must pass these rigorous tests.
If not it is rejected and returned to the production line
for repair. Samples are pulled from the line for further testing.
Mechanical inspection is done throughout the manufacturing process. Before each
amplifier is packed it is fully inspected again for any cosmetic flaws. Any damaged or
any part which is out of specification is replaced.
Zed takes pride in what we design and manufacture and we trust that this shows in the
final product.
