HEADPHONE OUTPUT This 1/4" TRS connector supplies the output to your stereo headphones. It is the same signal that is routed to the control room outputs [16], as determined by the control room/phones source matrix [44, 45]. The volume is controlled with the phones knob [48], right next to the control room knob [47]. Whenever a solo switch [41] is engaged, you will only hear the soloed channel(s) in the headphones. This gives you the opportunity to audition the channels before they are added to the main mix. (Solo signals reaching the headphones are not affected by the channel level or main level, therefore turn down the phones level first, as soloed channels may be loud.) The phones output follows standard conventions: Tip = Left channel Ring = Right channel Sleeve = Common ground WARNING: The headphone amp is loud, and can cause permanent hearing damage. Even intermediate levels may be painfully loud with some headphones. BE CAREFUL! Always turn the phones level control [48] all the way down before connecting headphones or pressing a solo switch, or doing anything new that may affect the headphone volume. Then turn it up slowly as you listen carefully. 43. LAMP This female BNC connector provides 12 volts DC on its center pin. Connect any quality gooseneck lamp here. OO 53 MAX TAPE IN 54 TAPE TO MAIN MIX OO MAX SOLO LEVEL 52 PFL AFL SOLO MODE Control Room/Phones and Meters Typically, the engineer sends the main mix to an audience (for a live show) or to a mixdown deck (if recording). But what if the engineer needs to hear something other than the main mix in the control room or headphones? With the Onyx 1640i, the engineer has several choices of what to listen to. This is one of those tricky parts, so buckle up. 44. MAIN MIX Press this switch in to listen to the main mix in your control room and headphones, and to check the main mix levels in the meters. In addition to the main mix, you can listen to any combination of tape, FireWire and recording outs, depending on which of these switches [45] is engaged. If the assign to main mix switch [46] is engaged, you cannot hear the main mix in the control room or headphones, or see its level on the meters. This is to prevent feedback caused by sending the main mix to the main mix. Owner's Manual 19
