The AVR250 rear panel

Positioning the unit

nPlace the receiver on a level, firm surface.

nAvoid placing the unit in direct sunlight or near sources of heat or damp.

nDo not place the unit on top of a power amplifier or other source of heat.

nEnsure adequate ventilation. Do not place the unit in an enclosed space such as a bookcase or closed cabinet unless there is good provision for ventilation. The receiver is designed to run warm during normal operation. We recommend a minimum distance of 50mm (2 inches) around the sides and top of the appliance to provide adequate ventilation.

nMake sure the IR receiver in the centre of the front panel display is unobstructed, otherwise this will impair the use of the remote control. If line-of-sight is impractical, an infrared remote repeater can be used with the rear panel IR connector.

nDo not place your record deck on top of this unit or any other unit which is mains supplied. Record decks are very sensitive to the noise generated by mains power supplies which will be heard as ‘hum’ if the record deck is too close.

Do not place any other component or item on top of the AVR250 as this may obstruct the ventilation holes, causing the AVR250 to run hot. (The unit placed on top of the AVR250 would become hot, too.)

Notes on installing the AVR250

The inputs are named to make it easier to reference when connecting source components to the AVR250 (e.g., a DVD or VCR), but all inputs have the same circuitry. This means that there is no reason why you should not connect a different device from that labelled to any of the inputs. For example, if you had two DVD players and the AV input was not being used, then the second DVD player could be connected to the AV input.

Cables

We recommend the use of high quality screened analogue, digital and video cables, since inferior quality cables will degrade the overall quality of your system. Use only cables that are designed for the particular application as other cables will have different impedance characteristics that will degrade the performance of your system (for example, do not use cabling intended for audio use to carry video signals). All cables should be kept as short as is practically possible.

Video and digital connections must be made with cables that are designed for this purpose, i.e., coaxial cable with a 75Ω impedance. If substandard cables are used you may suffer from poor picture quality such as ghost images and/or grainy picture quality (snow).

Speaker cables should be kept short to ensure efficient power transmission and avoid audible distortion.

It is good practice when connecting your equipment to ensure that the mains power supply cabling is kept as far away as possible from your audio and video cables, as this will provide the best sound and picture quality. Failure to do so may result in unwanted noise in the audio and video signals.
