Input And Output Connections - Creek Audio EVOLUTION 50A Instruction Manual

INPUT AND OUTPUT CONNECTIONS

On the rear panel there are 4 standard Line level* inputs labelled 1-4. Some of these in-
puts can be configured for different requirements and these options are described below.
Input configuration 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 typ-
ically characterised by a voltage level of between 300mV and 2V r.m.s. The EVOLUTION 50A will
accept levels between 0 to 5.4V r.m.s. and should therefore be compatible with all sources.
Line 1 is suitable for any source (CD, Tuner, Tape, etc), and can also be used as a dedi-
cated MM / MC Phono Input when an optional Creek Plug-in Phono pre-amp is fitted. See
separate section below.
Line 2 is suitable for any line level source.
Line 3 has two possible functions. Firstly as an additional line level input, equivalent to
Line 2 or secondly, as a direct input to the power amp, bypassing the internal pre-amp and
volume control. Known as "AV Direct" this is useful for AV applications where the EVOLU-
TION 50A can be used for the front Left and Right channel sound, with volume controlled
by the AV receiver. This allows a multi-channel AV system to be integrated into your high
quality 2-channel hi-fi system with ease. Simply connect the Line 3 input to your AV ampli-
fier's Front L/R pre-out connections.
AV Direct also makes it possible to "Slave" the amplifier to another EVOLUTION 50A us-
ing the pre-out connection, thus producing a bi-amplified system.
Line 4 duplicates the dual functionality of the Line 3 input whilst also adding a different
connection option. Connections for standard line level RCA jacks are provided but equip-
ment with Balanced outputs* can also be connected to the provided XLR input connectors.
Use only one or other connection method, not both!
*Balanced outputs use a differential signalling technique which makes the interconnection much
more resistant to external noise and interference. It is ideal for preserving signal fidelity, especially
if long cable runs are required.
