SURROUND BYPASS

Please refer to chapter

5.3

before use INPUT 5 as a SURROUND

BYPASS.

5. 3 Using the 5

input SURR. as a SURROUND BYPASS

The so-called SURROUND BYPASS of ACCUSTIC ARTS® is a configuration option that allows the signal of a

surround processor to be "looped through" without further amplification by the POWER I. That is, the

volume of this signal is controlled by the external processor or preamp and not by this amplifier. This

makes it possible to combine a high-end audio system with a home cinema system and this without loss

of quality.

The POWER I is in this case like a "pure" amplifier to see.

In the factory setting, the 5th input (SURR. / INPUT 5) is designed as a pure high-level input, comparable

to the unbalanced inputs 3 and 4.

Important NOTE:

When using the SURROUND BYPASS input, do not connect "standard equipment" such as CD players,

etc., because the volume of this input can not be adjusted. This means that an applied signal is

transmitted at full volume to the speakers or via the preamp output. This can destroy the amplifiers

or speakers.

5. 4 Use of the PRE OUT

As mentioned before, you can use the POWER I in principle as a preamplifier to control another,

additionally connected power amplifier or an (active) subwoofer. Connect the preamp output PRE-OUTPUT

to the corresponding input of your power amplifier. In the menu control, note that this output is to be set

as PRE-OUT [menu 4, setting (1)].

Please use only high-quality interconnect cables. This is the only way to ensure that the sound quality of

the POWER I is fully exploited.

5. 5 Use of the headphone output PHONES

On the front panel of the POWER I is the headphone jack (6.3 mm jack). This is marked with PHONES

(abbreviation for headphones = headphones). The headphone jack is covered with a chrome button, which

is held by a pin in the front panel. This cover not only looks good, but also prevents the ingress of dust

when not in use.

Via the menu control, see point 7.7, the headphone output can be switched on and off. So that you can

listen to music undisturbed via headphones, the loudspeakers can be switched off via the menu control,

see section 7.8.

5. 6 Loudspeaker cables

For each channel the POWER I has one pair of high quality loudspeaker terminals. Please use only high

quality loudspeaker cables. This is the only way to ensure that the sound quality of the power amplifier is

fully exploited.

Loudspeaker cables from ACCUSTIC ARTS

are excellently matched to the needs of the POWER I. But

naturally other high-quality brand name products may also be used.

To connect the cables to the power amplifier or loudspeakers if possible use high quality terminal ends or

banana plugs and avoid connecting bare litz wires (except with OFC copper cables) since these corrode

and so restrict the signal flow.
