recommend that you stack high fidelity components on top of one another
as this could interfere with ventilation.
You may not place any Ovation High Fidelity product directly on a carpet
as this will obstruct airflow and will lead to overheating.
Make sure when locating the product, that no liquids or any other foreign
objects can enter the unit through the ventilation holes.
Keep this equipment out of the reach of children.

Connecting a Preamplifier Your Model 1701 Stereo Power Amplifier
The figure above shows how to connect your model 1701 power amplifier
to your preamplifier.
Note that you do not need to connect both the single ended and the
balanced interconnects –you only need to connect the single ended inputs
or the balanced inputs.
We recommend where possible, you use balanced interconnects for best
performance.
Always make sure that you have the ‘Input Select’ switch on the rear panel
in the correct position –depressed for balanced inputs and out for single
ended inputs.
We recommend the Ovation High Fidelity Model 1501 High Resolution
Stereo Preamplifier for use with the model 1701 Power Amplifier.
Connecting Loudspeakers to Your Model 1701 Stereo Power
Amplifier
Your model 1701 Power Amplifier is designed for operation with 8 Ωrated
loudspeakers. You should only connect 1 pair of speakers to your
amplifier for best performance.

Powering ON and OFF
To power up the amplifier, depress the black pushbutton located in the
center of the front panel. The green indicator LED beneath the pushbutton
switch will illuminate. You will hear a click after 3 seconds or so - this is
the in-rush power limiting relay energizing. After a further second or two,
the amplifier output will engage, allowing sound to come from the
loudspeakers.
To power down, simply press and release the push button again. After
about 3 seconds, the power in-rush relay will click as it de-energizes; the
amplifier will disengage the loudspeakers and the green indicator LED will
extinguish.
The Model 1701 amplifier is equipped with sophisticated protection
functions that include DC offset detection to protect your speakers, short
circuit protection and power-up and power-down muting. If any of these
protection features are activated, the unit will automatically disconnect the
loudspeakers.
Loudspeaker Short Circuit Protection - Important
If the load impedance of the speakers drops below about 2 Ohms when
the amplifier is delivering full output power
or
the connection from the amplifier to a loudspeaker experiences a short
circuit
the Model 1701 output stage protection circuit will activate. This will
instantly disconnect the loudspeakers from the amplifier to protect it and
the speakers from damage. The GREEN power LED on the front panel will
remain illuminated
To re-engage the loudspeakers, switch the amplifier OFF, wait for 10
seconds and switch the power back ON again.
Note that if the cause of the problem is a short circuit in your loudspeaker
connection, the amplifier will shut down again when re-applying power.
You should therefore always check to ensure you do not have a short
circuit in your loudspeaker connection after a shutdown.
Attention: Playing music at excessive volume levels can damage
your hearing.

Replacing the Fuses on your Model 1701 Power Amplifier
In the unlikely event that the mains fuse on your unit should blow, you
should check the following carefully before replacing it: -
1. You are using the correct mains voltage. The mains voltage for
your product is set at the factory at the time of shipping and shown
on the rear panel bottom left hand side of the unit.
2. On power amplifier products, make sure the speaker outputs are not
shorted in any way.
3. Make sure the mains power at the wall socket is not inadvertently
switched OFF.
4. If your unit still does not operate, you need to replace the fuse as
detailed below
Important! Always unplug the unit from the mains
before attempting to replace the fuse!
Use a flat bladed screw driver and gently lever open the fuse drawer
Replace the Model 1701 fuse with the ratings as indicated below
Mains Voltage
Fuse Rating
Remarks
100 VAC to 130
VAC
6.3 A T
slow acting ‘T’ fuse
200 VAC to 240
VAC
3.15 A T
slow acting ‘T’ fuse
Firmly push the drawer closed, after which you can reconnect the unit to
the mains and then apply power.
Do not use fuses marked FF, F or M as these are fast/medium acting and
will likely blow when you power the amplifier up. Only use ‘T’ fuses.
If the fuse immediately blows again, refer your unit to a qualified repair
technician, or if still under warranty, contact the factory via the ‘Contact’
page at www.ovationhifidelity.com
Never use fuses rated higher than shown in the table above on your
Model 1701. Equipment fuses are designed and rated to prevent fire
hazard and are a legal requirement in all countries.
