[. . . ] Model 6176 Channel Strip Universal Audio Manual Number 65-0013 Revision 1. 2 Universal Audio, Inc. Santa Cruz, CA 95060 (831) 466-3737 voice (831) 466-3775 fax www. uaudio. com The 6176 Channel Strip Thank you for purchasing the 6176 Channel Strip. This unit brings together 1 channel of our 2-610 Mic Pre with an 1176 Limiter. The 610B was inspired by the microphone preamp section of the 610 console designed by my father, M. T. [. . . ] 3) With the 1176LN Input control full off (CCW) adjust the GR Zero Set trim pot So the meter reads 0 dB. 4) The GR Zero Set pot is located through a small hole on the front panel between the 1176LN Input and Output knobs. Join / Split The center section toggle switch labeled JOIN / SPLIT allows separate use of the 610B preamp and the 1176LN limiter. When the switch is "down" in the SPLIT position, each side of the 6176 is a separate device with associated in / out connections on the rear chassis. When the switch is "up" in the JOIN position, the 6176 behaves like a "channel strip" with the 610B output routed to the 1176LN internally. In this position, the 610B rear chassis output XLR is automatically disconnected. Stereo Operation Using an external 1176 Stereo Adapter (1176SA), which is available from Universal Audio, two units may be connected for stereo operation. Use the following procedure to calibrate the 1176 stereo adapter: 1) Remove the signals from both 1176 units. 2) Disable the gain reduction on each limiter (set both ATTACK controls fully CCW). 3) Connect the 1176-SA to both limiters (This requires two RCA style cables). 5) Adjust the potentiometer on the 1176-SA until both meters read 0dB. 6) If it is not possible to zero both meters, reverse the stereo interconnect cables and repeat the preceding step. Note: When used in stereo operation, the Attack and Release controls on the two units will interact. Controlling the Attack and Release on either of the units controls both units. When connected in a stereo configuration, the fastest attack time is double that of a single unit. 6176 Rear Panel On the left, the rear panel (Figure 3) has the 1176LN LINE INPUT and LINE OUTPUT XLR connectors. Also, there is an 1176LN Input Loading switch and an 1176LN Stereo Link jack. On the right, the 610B MIC INPUT, LINE INPUT, and LINE OUTPUT XLR connectors. These connectors and controls are discussed in the following sections. 12 15K W ! 1176 SA POWER IN: 115V ~ 50/60Hz 400ma 230V ~ 50/60Hz 200ma FUSE RATING: T 400ma L 115V~ T 200ma L 230V~ CAUTION / AVIS CE LINE OUTPUT LINE INPUT MIC INPUT LINE OUTPUT LINE INPUT 600 W RISK OF ELECTRIC SHOCK DO NOT OPEN RISQUE DE CHOC ELECTRIQUE NE PAS OUVRIR 6176 COMPRESSOR UNIVERSAL AUDIO, ·SANTA CRUZ, CALIF.

Pin 2 is positive on the 610B LINE OUTPUT when the front panel Polarity toggle switch is down (IN ). Pin 3 is positive on the 610B LINE OUTPUT when the front panel Polarity switch is up (OUT ). 1176LN Input Loading The 1176LN Input Loading switch is located to the right of the LINE INPUT XLR. When the button is pushed in, the input impedance will be 600 ohms, typical of older vintage gear. [. . . ] It doesn't change the way the bass sounds, it just keeps the level at a more controllable place. " Mixer Ken Kessie (En Vogue, Tony!"Seems like everybody knows the basic tricks for the 1176, " he says, "But here are two that might be lesser known. If you turn the attack knob fully counterclockwise until it clicks, the 1176 ceases to be a compressor and acts only as an amplifier. And of course the unit can be overdriven, adding another flavor of distortion in case your plug-ins are maxed out!" "Then, for that hard-to-tame lead vocalist (the one that backs up from the mic to whisper and leans in for the big ending chorus), try an 1176 followed by a DBX 165. [. . . ]
