Danger
Exposure to extremely high noise levels may cause a
permanent hearing loss. Individuals vary considerably to
noise induced hearing loss but nearly everyone will lose
some hearing if exposed to sufficiently intense noise for a
sufficient time.
The U.S. Government's Occupational Safety and Health
Administration (OSHA) has specified the following
permissible noise level exposures:
According to OSHA, any exposure in the above permissible
limits could result in some hearing loss. Ear plugs or
protectors in the ear canal or over the ears must be worn
when operating this amplification system in order to prevent
a permanent hearing loss. If exposure in excess of the limits
as put forth above, to insure against potentially harmful
exposure to high sound pressure levels, it is recommended
that all persons exposed to equipment capable of inducing
high sound pressure levels, such as this amplification
system, be protected by hearing protectors while this unit is
in operation.
THIS SYMBOL IS INTENDED TO ALERT THE USER TO THE PRESENCE
OF NON-INSULATED "DANGEROUS VOLTAGE" WITHIN THE
PRODUCT'S ENCLOSURE THAT MAY BE OF SUFFICIENT MAGNITUDE
TO CONSTITUTE A RISK OF ELECTRIC SHOCK TO PERSONS.
THIS SYMBOL IS INTENDED TO ALERT THE USER TO THE PRESENCE
OF IMPORTANT OPERATING AND MAINTENANCE (SERVICING)
INSTRUCTIONS IN THE LITERATURE ACCOMPANYING THE UNIT.
1. Read all safety and operating instructions before using this
product.
2. All safety and operating instructions should be kept for
future reference.
3. Read and understand all warnings listed on the operating
instructions.

5. This product should not be used near water, i.e. Bathtub,
sink,swimming pool, wet basement, etc.
6. Only use dry cloth to clean this product.
7. Do not block any ventilation openings, It should not be
placed flat against a wall or placed in a built-in enclosure
that will impede the flow of cooling air.
8. Do not install this product near any heat sources ;such
as,radiators, heat registers, stove or other apparatus
(including heat producing amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or
grounding-type plug. A polarized plug has two blades with
one wider than the 0ther.A grounding-type plug has two
blades and a third grounding prong. The wide blade or the
third prong are provided for your safety If the provided plug
does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.
10. Protect the power cord being walked on or pinched,
particularly at Plugs, convenience receptacles and the point
where they exit from the apparatus. Do not break the ground
pin of the power supply cord.
11 . Only use attachments specified by the manufacturer.
12. Use only with the cart, stand, tripod, bracket,
or table specified by the manufacturer or
sold with the apparatus. When a cart is
used, use caution when moving cart/
apparatus combination to avoid injury
from tip-over.
13. Unplug this apparatus during lightning storms or when
unused for long periods of time.
14. Care should be taken so that objects do not fall and liquids
are not spilled into the unit through the ventilation ports or
any other openings.
15. Refer all servicing to qualified service personnel. Servicing
is required when the apparatus has been damaged in any
way; such as, power-supply cord or plug is damaged, liquid
has been spilled or objects have fallen into the apparatus,
the apparatus has been exposed to rain or moisture, does
not operate normally or has been dropped.
16. WARNING: To reduce the risk of fire or electric shock, do not
expose this apparatus to rain or moisture.
17. The MAINS plug or an appliance coupler is used as the
disconnect device, the disconnect device shall remain
readily operable.

Cabinet Cabinet
Amplifier Loading Chart
Cabinet A’s Impedance (ohms)
This chart can help you determine what load (ohms) is present on the amplifier when using multiple cabinets.
- To use this chart with two cabinets (A and B), find cabinet A’s impedance (ohms) column and cabinet B’s
impedance row on the chart. The total load on the amplifier is shown in the box where they meet. For example: If
cabinet A’s impedance is 8 ohms and cabinet B’s impedance is 4 ohms, the total load on the amplifier would be 2.67
ohms.
- To use this chart with three or more cabinets, find the total load for two cabinets and then use the result for
cabinet A’s impedance column. The third cabinet will then be used for cabinet B’s impedance row on the chart.
Find the total load on the amplifier and repeat if more cabinets are used. For example (using 3 cabinets): If the first
cabinet (cabinet A) has an impedance of 16 ohms and the second (cabinet B) has an impedance of 8 ohms, the
total load would be 5.33 ohms. Using this load (5.33) as cabinet A’s impedance and a third cabinet’s (new cabinet
B) impedance of 4 ohms, you would find that the total load on the amplifier is 2.29 ohms. It is not
recommended to use any combination of cabinets that has a resulting load in a shaded area of the chart.

GROOVE 1300™
Specifications
The GROOVE 1300™ was designed to mount into a standard 2-space rack. When mounting, use 4 screws to
secure the amplifier to the rack. When using only one amplifier, use the bottom 2 spaces in the rack.
However, if more than one amplifier is used, leave one space open between the amplifiers to ensure proper
ventilation (shown below).
