Speck Electronics EQ16 - Manual (Page 9)

5
The Model EQ16 is delivered in a special, protective container and was
carefully inspected both mechanically and electrically before shipment.
It should be physically free of mars and scratches and in perfect
electrical order upon receipt. To confirm this, the product should be
inspected for physical damage that may have occurred in transit. Any
damage should be reported to your dealer or delivery company as soon
as possible.
The Model EQ16 will operate satisfactorily over a wide range of
ambient temperatures. The EQ16 will operate from 10 to 50 degrees C
and the external power supply will operate from 0 to 40 degrees C. If
the EQ16 is installed in an equipment rack that also contains heat
producing equipment such as power amplifiers or other power supplies,
adequate ventilation should be provided. This will prolong component
life and maximize operational stability.
While the internal circuitry of the EQ16 is fully shielded by the steel
chassis, installation should nevertheless be planned to avoid locating it
or any low level audio equipment immediately adjacent to power
amplifiers, power supplies, or any source of electromagnetic emissions.
To protect operating personnel, the National Electrical Manufacturers
Association (NEMA) recommends that the instrument panel and rack
cabinet be grounded. All Speck power supplies are equipped with a
three conductor power cord which, when plugged into an appropriate
receptacle, grounds the power supply.
The three conductor line cord and plug assembly is wired in
accordance with NEMA convention (line - black, Neutral - white, and
safety earth - green). Audio signal grounds and DC grounds from the
EQ16 are isolated from the AC safety earth.
When using the EQ16 and its power supply outside North America, it
may be necessary to adapt a different power cord for that specific
country.
