Anthem Audio PRE 1L Operating Manual - page 11
BR EAK- IN TI ME
As with all audio electronic products, the ultimate sonic
character of the Pre 1L will not be realized until and unless
the unit receives a minimum of approximately 70 hours
of signal break-in time (i.e. the Pre 1L is on and producing
an output signal).
P LACE MENT FOR PR OPER VENTILAT I O N
Allow at least 4” (15 cm) of clear space above the Pre 1L
chassis for proper ventilation, making sure the air vent slots
in the chassis cover remain unobstructed. Also, be sure
that the Pre 1L is placed on a secure, hard and level sur-
face (not on carpet).
S AFETY INSTRU CTI ONS
1. Ventilation - Although your Pre 1L generates only nominal
heat in use, be sure that the ventilation slots in the top cover
have at least 4” of unobstructed air space above them.
2. Water and Moisture - This product should not be used
near water. To prevent fire or shock hazard, do not expose
this product to rain or moisture.
3. Heat - This product should be situated away from heat
sources such as radiators, heat registers, stoves, or other
appliances which produce heat.
4. Power Sources - This product should be connected to an
AC power source of the proper rated voltage. The original
shipping container will stipulate the AC voltage this unit can
operate with correctly.
5. Cleaning - A regular dusting with a soft, non-abrasive
cloth will generally keep the finish of the faceplate and chas-
sis looking like new. At no time should you allow any liquid to
come in contact with the Pre 1L; it may run into the electron-
ic circuitry and cause damage which will not be covered
under your warranty.
6. Servicing - Do not open this product. No user serviceable
parts inside. Refer servicing to an authorized service technician.
7. Non-Use Periods - The power cord of this product should
be unplugged from the outlet when left unused for an
extended period of time.
8. Do not remove the Pre 1L covers while the unit is “on”, or
connected to an AC power source. Cover screws could fall
through the ventilation slots and cause electrical damage to
the Pre 1L.
