[. . . ] do this: Press the Volume / Balance button once to change the function of the Rotary Control to Balance adjustment. The Balance indicator over the button lights when Balance adjustment is selected. Press the button again to change back or just wait 5 seconds for the unit to time-out. The Volume / Balance button doubles as the Function Menu Select button ­ see page 19 for details. Rotary Control x This control is dual function. In normal use, it sets the Volume or Balance, but while the menu is open, it scrolls through that. For best results, set the Volume to a fairly high level (say between -20. 0 and -10. 0) while playing music at typical listening levels. If using a preamplifier Volume control instead, set Elgar Plus Volume to 0. 0 (maximum).

It should be set to suit your system ­ there are two levels: High (6V rms) and Low (2V rms). For best results, Elgar Plus' Volume control should be set to no lower than -20. 0 for normal listening levels with typical music. We suggest you start with the Low setting and change to the High setting if this is inadequate. Before adjusting the Output Level switch, please ensure you are not playing music at a high level ­ the High setting is noticeably louder.

For best results, connection of these outputs to unbalanced inputs is not recommended ­ use the Unbalanced Analogue Outputs instead. Use good quality, screened, XLR audio cables. Unbalanced Analogue Outputs For unbalanced equipment, use the Unbalanced Outputs with good quality, screened, RCA phono audio cables. It is much better to use these for equipment with a single-ended input, than to use half of a balanced output. Doing so may cause ground loop hum pickup. AES/EBU Digital Inputs The AES 1 and AES 2 inputs may be used individually for digital signals with sample rates up to 96kS/s. The Dual AES interface allows a 192, 176. 4, 96 or 88. 2 kS/s 24 bit signal to be encoded as two standard 96, 88. 2, 48 or 44. 1 kS/s 24 bit AES data streams respectively. Elgar Plus decodes the dual data stream and converts it to wide band analogue. See Dual AES on page 23 for more information. IMPORTANT! Please ensure the two AES inputs are correctly connected to the source for Dual AES operation or the channels will be swapped. This usually involves connecting AES 1 (or AES A) on the source to AES 1 on Elgar Plus and AES 2 (or AES B) on the source to AES 2 on Elgar Plus. Use with 110 ohm screened, twisted pair cable designed for digital audio or RF. Do not use unscreened cables as they may pick up interference from other appliances. SPDIF Digital Inputs The RCA1, RCA2 and BNC inputs are used individually for digital signals with sample rates up to 96kS/s. Some types of audio cable are not suitable and may cause crackling noises or other malfunctions. Toslink and ST Optical Inputs The Toslink and ST inputs are used for optically transmitted digital signals with sample rates up to 48kS/s.
