Display the source you want to configure, together with the current video input, as described in the previous sections. For example, to configure the CD video input choose: CDLV l Press V or A to choose the video input. For example, if you always want the TV picture when you select CD set it to: To set up a source for simultaneous broadcasts CDV5 . Choose a source you are not already using. . Assign a suitable label to the source; SB is suggested. . Configure the audio input to A3 (Radio). . Configure the video input to V5 (TV). When you select the source you have configured you will get radio sound and a TV picture, as required for simultaneous broadcasts. To set up a system with two CD players . Configure the source you are going to use for the first CD player. For example: Source CD, Label C1, Audio input A2, Comms type 1C, Address 1A. . Configure the source you are going to use for a second CD player, with a different address. For example: Source CDR, Label C2. Audio input A3, Comms type 1C, Address 2A. The remote control will now automatically control whichever of the CD players you have selected with the CD or CDR source keys. Customising 27 Customising the Control Unit 28 Customising the Control Unit 28 Programming levels The 501/501V Control Unit allows you to program the level of each source independently, to suit your other equipment, so that when you switch between sources the volume stays the same. When you are programming levels the control unit operates as a preamplifier with a fixed volume setting equivalent to 65. This level is chosen to be comfortably loud on average sources. You can switch between sources and adjust the relevant input levels to achieve the setting you want. You can increase the sensitivity of any source by up to 15 steps of 1dB. The loudest source, usually CD, should therefore be chosen as the reference. To balance input levels . Switch off any power amplifiers that are connected to the control unit. . Turn off the control unit, using the power switch on the back panel. . Turn on the power again while holding down the Mute key on the front panel. The display will show: Gain l Release the Mute key. The display will show the normal standby condition: . . Select the source that sounds loudest and make it your reference. l Switch to another source in the usual way. l Use the A and V keys to change the sensitivity. For example, the display will show: 12dB . Switch between the source you are changing and the reference source until they sound equally loud. l Repeat the procedure for your other sources. . When you have finished programming levels, switch the power off and on again to restore the control unit to normal operation. If you know the output level of your sources you can probably set the gains by calculation. The following table shows the correspondence between the gain and sensitivity on the standard audio inputs and on the LP inputs: Gain A2-A6 LP MM LP MC 0dB 150mV 3mV 210mV 3dB 110mV 2.2mV 150mV 6dB 75mV 1.5mV 110mV 9dB 54mV 1.1mV 75mV 12dB 38mV 750mV 54mV 15dB 27mV 550mV 38mV Customising 29 Cu...
