Creek Audio 5250, 5250SE Operating Instructions Manual

Operating Instructions

Thank you for purchasing the 5250 ampli fier You are now in possession of a Stat e of the Art
Integrated Amplifi er The f unctions and operation of the 5250 and Speci al E di tion are exactly the
same and are very simple However the foll owing notes are provided to explain all aspects of it s
design and use

MAINS CONNECTION

When unpacking the amplifier please keep the packing material
in a safe place for possible future use In the pack there is a
separate mains cable sui table for connecting to the mains supply
in the country of use The IEC socket end of the cable should be
firmly inserted into t he connector on the rear panel marked
"Mains Input’

Remember do not overload the m ai ns wall socket with too many
plugs or adaptors The high quality performance of the amplifier
will be impaired if the electrical supply to it is in poor condition If
in doubt consult a qualified electrician or your dealer

The Mains Input’ connection is also fi tted with a fuse specifical l y
suited to the supply voltage of t he country of use The correct
value is clearly marked on the rear panel next to the Mains Input

Should it be necessary to replac e the fuse ensure that you

use the same type as spec i fied on the rear panel i e

5 x 20mm cartridge type: T 3.15 A surge resisting for
220-240V 50Hz AC, T 6 3 A surge resisting for 110­120V 60Hz AC or an T 8A surge resisting for 100V
(Japan)

LOUDSPEAKER CONNECTIONS

The loudspeakers should be connected using a suitable pair of cables designed specifically for
audio use. Two pairs of screw terminals marked ’A’ allow for either bare wire or spade lug
connectors to be passed through the hole or around the bush. Tighten the term i nal fully after fitting
the speaker wire. Please consult your dealer for advice if you are unsure.
It is very important to connect the loudspeakers to the loudspeaker terminals in the correct phas e.
Cables are normally polarised with a line or a raised bump on the positive side. If one channel is not
connected in the same f ashion as the other, a severe loss of bass performance and a spreading of
the stereo image will result.

A second set of term i nal s marked ’B’ allow the user to select from the rotary control in the centre of
the front panel, the option of having two pairs of speakers running separately, or together. The
options include speakers off, when using headphones, speakers A, speakers B and speakers A and
B together.

It is not recommended to use loudspeakers of les s than 40 resistance or more t han two pairs of 80
speakers running from the amplifier at one time. However, bi-wiring of one pai r of speakers, using
the four terminal posts, can improve the sound of your s ys tem (consult your dealer for more details).

M.B. It is VERY IMPORTANT not to short the loudspeaker cables together when the other
ends are still connected to the amplifier, otherwise permanent damage can result. If i t i s
necessary to move or change the location of your loudspeakers, make sure that you switch
off the amplifier from the main s fi rst.

INPUT CONNECTION AND SWITCHING

On the 5250 all six line inputs, incl udi ng the tape input, have zero gain (passive circuitry), which can,
if required, be increased by installing a Creek 5350 line stage pre-amp.
The tape input is in a loop with the tape output , enabling you to record anything you can hear, or in
other words, Monitor recordings without interrupting the signal. The rotary selector switc h on t he
left-hand side of the ampl i f i er i s used to select and list en to any of the desired inputs. The second
rotary selector switch on the 5250, marked Record, allows you to record any input independent of
the input you are listening to.
As all the line input levels are the same, it is not necessary to use the precise inputs as designated.
You may, for example, plug a CD player into the Tuner input and obtain exactly the same result and
performance as the dedicated CD input. For added flexibility, the first input on the 5250 can be used
either for vinyl Disc or Auxiliary Line.

An optional low noise

MM orMC Phono Amplifier Module

is available, which replaces the s tandard

passive Link pcb, internall y. Check with your dealer for more details i f requi red.

OUTPUT SWITCHING

Two pairs of speakers and one pair of headphones can be s el ected from the knob in the middle of
the front panel, marked Sp eakers. For listening through the headphones without loudspeakers,
select Off. If one pair of speakers is required, select position A or B , dependi ng on which sockets
have been used on the rear panel. In this way two pairs of speakers can be selected together or
separately.
