momentary switches, simply press

When using the “Slave/Aux In” port
(such as when using an IQ sys­tem), the system will automatically
turn on when the specified voltage
is present at the port. When this
happens, the previous system
state is saved and any momentary
switches that are attached be­come disabled. This will provide
priority access to the Crown IQ
user, preventing accidental shut­down. If you want off-control via
the IQ System, you will need to
start the IQ System first. If you want
to control the off function via the
momentary switches, you need to
have them turned on prior to turn­ing on the IQ System. When the

5 Technical Information

Since the
Crown’s CT-10 series of amplifiers,
it is important to note the safety
features present at turn-on with the
CT-10 amplifiers.

All CT-10 series amplifiers have a
four-second turn-on delay. This
prevents dangerous turn-on tran­sients. The CT-10 series also has
“soft-start” circuitry, which pro­vides low inrush, and eliminates
the need for power sequencers.

7 Service

This unit has very sophisticated cir­cuitry which should only be ser­viced by a fully trained technician.
This is one reason why each unit
bears the following label:

CAUTION: To prevent electric
shock, do not remove covers. No
user serviceable parts inside. Re­fer servicing to a qualified tech-

nician.

7.1 Changing the Fuse

1) Disconnect the IEC power cord
from the wall.

2) Insert a small, flat blade screw­driver into the pry slot. (The pry
slot is located opposite the IEC
power inlet on the power module
(See Figure 7.1). Pry the fuse ac­cess door open.

3) Note how the red fuseholder is ori­ented (See Figure 7.2). For models
operating in the 100-120V range,
the 115V lettering will be on the right
and the letters PRSR will read
across the top. In all other models,
the 230V lettering will appear on the
right. After observing the orientation
of the fuse holder, use your small
screwdriver to pry it out. Be careful,

the fuse may pop out immedi­ately when removing the holder.

4) Remove the fuse from the holder.

5) Replace the fuse with one of the
same rating.

6) Re-insert the red fuseholder, taking
care to properly put it back in the
same orientation it was in step 3.

7) Snap fuse access door closed.

8) Connect IEC power cord.

7.2 Worldwide Service

Service may be obtained from an
authorized service center . (Contact
your local Crown/Amcron repre­sentative or our office for a list of
authorized service centers.) To ob­tain service, simply present the bill
of sale as proof of purchase along
with the defective unit to an autho­rized service center. They will
handle the necessary paperwork
and repair.

Remember to transport your unit in
the original factory pack.

7.3 North American Ser­vice

Service may be obtained in one of
two ways: from an authorized ser­vice center or from the factory. You
may choose either. It is important
that you have your copy of the bill

of sale as your proof of purchase.

7.3.1 Service at a North American

Service Center

7.3.2 Factory Service

To obtain factory service, fill out the
service information page that fol­lows and send it along with your
proof of purchase and the defec­tive unit to the Crown factory. For
warranty service, we will pay for
ground shipping both ways in the
United States after receiving cop­ies of the shipping receipts. Ship­ments should be sent “UPS
ground.” (If the unit is under war­ranty, you may send it C.O.D. for
the cost of freight via UPS ground.)
The factory will return it via UPS
ground. Please contact us if other
arrangements are required.

Factory Service Shipping In­structions:

1. When sending a Crown prod­uct to the factory for service,
be sure to fill out the service
information form that follows
and enclose it inside your
unit’s shipping pack. Do
send the service information
form separately .

2. To ensure the safe transpor­tation of your unit to the fac­tory, ship it in an original
factory packing container. If
you don’t have one, call or
write Crown’s Parts Depart­ment. With the exception of
polyurethane or wooden
crates, any other packing
material will not be sufficient
to withstand the stress of
shipping. Do not use loose,
