Operator Manual
Location
• Ideally a cool area is preferred not in close proximity to power distribution
equipment or other potential sources of interference.
• Do not install the equipment in places of poor ventilation.
• Do not install this equipment in a location subjected to excessive heat, dust or
mechanical vibration. Allow for adequate ventilation around the equipment, making
sure that its fans and vents are not obstructed. To prevent excessive heating of the
equipment, avoid mounting it directly above power amplifiers or other devices that
radiate significant amounts of heat such as, radiators and heaters. Keep the
equipment out of direct sunlight.
• Do not place the equipment in an unstable condition where it might accidentally fall
over.
• Make sure that the mains voltage and fuse rating information of the equipment will
be visible after installation.
Audio connections
To ensure the correct and reliable operation of the equipment, only high quality
balanced, screened, twisted pair audio cable should be used.
XLR connector shells should be of metal construction so that they provide a screen
when connected to the console and, where appropriate, they should have Pin 1
connected to the cable screen.
Radio frequency interference
Class A device
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own expense.
Electric fields
Caution:
In accordance with Part 15 of the FCC Rules & Regulations, “… changes or
modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.”
Should this product be used in an electromagnetic field that is amplitude modulated by
an audio frequency signal (20Hz to 20kHz), the signal to noise ratio may be degraded.
Degradation of up to 60dB at a frequency corresponding to the modulation signal may
be experienced under extreme conditions (3V/m, 90% modulation).
