Before you start! Introduction The AVR250 is a high quality and high performance home cinema processor and multi-channel audio amplifier built to Arcam’s traditional high quality design and manufacturing standards. It combines high resolution digital processing with high performance audio and video components to bring you an unrivalled home entertainment centre. In addition to the built-in tuner, the AVR250 allows switching and volume control of seven analogue and six digital sources, making

Before making connections Before connecting your equipment it is important to think about the following points, as these will affect your choice of connections and subsequent use of the system. Audio Wherever possible, connect both analogue and digital outputs of digital sources. This enables use of a digital input for the main zone with the corresponding analogue input used for recording onto an analogue tape deck or VCR, or for the Zone 2 output. Video The AVR250 allows for conversion betwe

Connecting loudspeakers The red and black terminals on the back of the AVR250 are used to make the connections to the loudspeakers. The speakers should be connected to the loudspeaker terminals, refering to the The speaker connectors labels on the rear-panel. on the rear-panel are labelled as follows: When connecting the speaker terminals of the amplifi er with the terminals on the speakers make sure that like polarities are matched (i.e., match “+” with “+” (usually red) and “–” with “

Connecting the AM and FM antennas FM antenna An FM antenna is required to receive VHF radio signals. AM Although a FM ribbon antenna is supplied as an accessory to the AVR250, for optimal FM radio reception fq GND a roof- or loft-mounted aerial is advised as this will give superior reception. (It is recommended that any roof-top antenna is fi tted by an experienced contractor as a contractor will be able to align your antenna FM to the nearest FM transmitter.) fr In some areas cable radio ma

Confi guring the AVR250 The AVR250 ‘Set-up Menu’ has six ‘Basic’ and fi ve ‘Advanced’ menu screens that take you through the confi guration process. The ‘Basic’ menus enable you to match your AVR250 to your speakers; the ‘Advanced’ menus allow you to optimise the operation of your system. Screen shots of these menus are shown in shaded boxes on the following pages. The best way to set up the AVR250 is using the on-screen display (OSD). To view the OSD for the initial set up, use the composit

The ‘Basic’ Set-up Menus 1 – General Settings: Max Volume: This limits the maximum volume setting the system can be turned up to. This is a useful feature to prevent accidental overdriving of low power- handling speakers, for example. Max On Volume: Limits the maximum volume the system operates at when it is fi rst switched on. The system comes on at the ‘Max On Volume’ if the last used (possibly very loud) volume exceeds this value. Delay units: Controls whether the delay settings for the sp

HQ Video: Choose between RGB or YUV; if you have a YUV display, set this item to YUV, otherwise set it to RGB. This setting controls the routing of the HQ-video within the AVR250, either as 3-wire YUV or 4- wire RGB signals (with the synchronisation signal on composite for RGB). In addition, it controls the operation of the S-video/composite-to-HQ video converter. When set to YUV, incoming composite and S-video signals are converted to YUV; in RGB mode, the iincoming signals are converted to

Front right Sub Stereo: This setting allows the volume level of the subwoofer to be adjusted for when the subwoofer is being used with 2-channel (stereo) sources. The subwoofer level for stereo music often needs to be set at a lower level than that for cinema use; use this trim setting, with a stereo source, to reduce the subwoofer output in stereo playback to an acceptable level. The level required depends on various factors such as speakers, the types and styles of music to be played and p

5 – Level settings The relative sensitivity of different speakers can lead to some speakers sounding disproportionately loud or quiet, relative to others in the system. The level settings of your AVR250 can help to address this inbalance. It is important to calibrate the speakers correctly to achieve an accurately centred sound stage. If possible, we recommend you use a sound pressure level meter (SPL meter) to perform this part of the set-up as it is diffi cult to judge the levels accuratel

Use these adjustments sparingly to compensate for speaker response problems caused by positioning, adjacent surface textures, or mixed brands of loudspeakers. Work with one speaker on at a time and, as an example, use the bass control to reduce boom problems for speakers placed in corners, and the treble control for speakers placed

This is a useful feature to prevent accidental overdriving of low power-handling speakers, for example. Fix Vol: This selects between fi xed and variable audio output to Zone 2. If NO is selected, the output level can be controlled from Zone 2 or the main system. If you wish to fi x the volume level, fi rst set the Zone 2 volume to the desired level, then select YES. Max
