Integrated Amplifier
Instruction Manual
Rev 1.1
Thank you for purchasing a Creek Audio EVOLUTION 100A Integrated Amplier. You are
now in possession of a State of the Art performance product. The functions and operation of
this integrated amplier are simple, however, the following notes are provided to explain all
aspects of its design and use. For simplicity we will now refer to the amplier as the ‘100A’.
Although this User Manual is intended to provide the latest instructions for use, it is possible
that a later version may be available to download from the Creek website.
Please check at www.creekaudio.com Go to the EVOLUTION 100A product page and click on
the tab marked Instructions.
UNPACKING AND LOCATING THE AMPLIFIER
When unpacking the EVOLUTION 100A please keep all the packing material in a safe place
for possible future use. In the carton there is a separate mains cable suitable for connecting
to the mains supply in the country of use. You will also nd a remote control unit and batter-
ies.
Make sure that the EVOLUTION 100A is on a suitable table, shelf or hi- equipment cabinet.
It is important to allow good ventilation to the heat-sinks inside the case. Avoid obstruction of
the ventilation slots on the top and bottom of the EVOLUTION 100A. It may be necessary to
place the EVOLUTION 100A on the top of other equipment, or a separate shelf to allow for
this. Do not place it at the bottom of a stack of equipment, as it may get too hot and switchoff, with an over-temperature warning on the display.
MAINS CONNECTION
IMPORTANT: Please check that the voltage selector switch on the bottom of the amplier
is set to the correct supply voltage for your region. Permanent damage can be caused by
using an incorrect setting.
The IEC socket end of the supplied cable should be rmly inserted into the connector on the
rear panel. Connect the mains plug to your AC outlet. Do not overload the mains outlet with
too many plugs or adaptors. The high quality performance of the 100A may be impaired if
the electrical supply to it is in poor condition. If in doubt, consult your hi- dealer, or a qualied electrician for advice.
The Mains Input connector on the rear panel is also tted with a fuse in a pull-out drawer.
The value of the 5 x 20mm cartridge fuse is clearly stated (T8AL 250V) next to the socket,
on the rear panel. This means it is a 8 Amp Time-lag (Anti-surge) type fuse, rated at 250V.
Always replace the fuse with one of identical rating to prevent the risk of re!

INPUT AND OUTPUT CONNECTIONS
On the rear panel there are 5 Line level* inputs labelled 1-5. Inputs 3 and 4 can be congured for different requirements and these options are described below. Input conguration
is controlled by a special menu which is available only during power-up, please see the
section below.
*Line level refers to a standardised way of transferring audio signals between equipment. It
is typically characterised by a voltage level of between 300mV and 2Vr.m.s. The 100A will
accept levels between 0 to 5.4V RMS and should therefore be compatible with all sources.
Line 1 is suitable for any line level source, such as CD, Tuner, Tape, etc. Line 1 can also
be congured for MM/MC Phono input. To congure for Phono input, an optional Creek
Sequel 40/48/54 mk2 pre-amp should be tted inside. See separate section below.
Line 2 is suitable for any line level source, such as CD, tuner, Tape, etc.
Line 3 is suitable for any line level source, such as CD, tuner, Tape, etc. Alternatively, Line
3 can be congured as AV Direct. This means the input passes the signal directly to the
100A’s power amp, bypassing the internal pre-amp and volume control.
AV Direct allows a multi-channel AV system to be integrated into your high quality 2-channel hi- system with ease. Simply connect the Line 3 input to your AV amplier’s Front L/R
pre-amplier output connections. The AV receiver must control the volume.
AV Direct makes it possible to “Slave” the amplier to another 100A using the pre-out connection, thus producing a bi-amplied system.
AV Direct also is the best choice for operating the 100A with the Creek EVOLUTION
50CD, DAC or Pre-amp, when its output is congured with digital volume control.
Line 4 is similar to Line 3, but offers either XLR or RCA input connectors. Do not use both
connection methods simultaneously.
*Balanced connections use a differential or symmetrical technique that is more resistant to
external noise and interference. It is ideal for preserving signal delity and low noise over
longer cable runs.

Line 5 is suitable for any line level source, such as CD, tuner, Tape, etc.
Line 5 is mounted on a removable expansion port that allows for two optional upgrade paths:
In place of Line 5, it is possible to t an AMBIT Tuner, or RUBY DAC, which can be installed
by your dealer.
Pre-out is an output signal that duplicates the signal to the 100A’s internal power amplier
section. It is affected by all the controls of the amplier such as volume, tone, etc. and allows the user to drive another power amp if required. This can be used to “bi-amp” a suitably
equipped pair of loudspeakers or to connect an active sub-woofer for example.
CONFIGURING THE INPUTS
To access the input conguration menu the product must be switched off. Hold down the
MENU key whilst turning on the power and release once you see the “Setup Menu” appear.
Here you will see the options for input conguration and restoring factory defaults. The tree
looks like this:
Line 3 Options –
Line Level Input Default setting. The input is conventional.
Power Amp Input This bypasses the internal pre-amp giving “AV Direct” mode.
Line 4 Options –
Line Level Input Default setting. The input is conventional.
Power Amp Input This bypasses the internal pre-amp giving “Line 4 Direct” mode.
Factory Defaults Restores all settings to original factory states.
Navigate using the left-hand rotary control; pressing the control selects the option. Once
congured press the MENU key again and the product will start up with the new settings.
Headphone Output
Headphones can be used via the front panel Jack socket. It can be used alone or together
with loudspeakers.
Go to MENU and make the selection via the Headphone switch option. When headphones
are plugged in, a headphone symbol will show on the bottom left hand corner of the OLED
screen.
