The lightning flash with arrowpoint in an equilateral triangle means that there are dangerous voltages present within the unit. The exclamation point in an equilateral triangle indicates that it is necessary for the user to refer to the owner's manual. These symbols warn that there are no user serviceable parts inside the unit. [. . . ] If the Peak LEDs flicker occasionally, the signal is approaching clipping levels, 3 The Front Panel · Monitor Mix Control The Omega gives you the ability to monitor your analog input signals while recording without the delay incurred by A/D/A converters and computer recording latency. This zero-latency analog monitoring is controlled by the Monitor Mix knob, which you can use to blend and adjust the ratio between OMEGA analog inputs and computer audio playback. Any signal coming in on the S/PDIF input is converted to analog and sent to the mix control so that you can monitor this input directly just like an analog input. To listen to just the source input signal, turn the Mix knob fully left to Direct. The Output from the Mix control is routed directly to the Line and Headphone outputs. This ability to blend and control the relative levels of computer audio playback and latency-free live analog inputs is effective when overdubbing. Lexicon Professional® communicating with your computer. · +48V LED This LED indicates that 48 Volt phantom power is active on the Mic 1 and 2 inputs. These inputs provide phantom power for condenser microphones that require it to operate. Phantom Power is activated by the switch labeled +48V Phantom on the bottom of the rear panel of the Omega. · S/PDIF Assign This button assigns the S/PDIF digital input to the USB 1-2 audio bus. When S/PDIF is enabled, only digital audio can use the USB 1-2 bus and any analog inputs that were assigned to USB 1-2 are disabled. Analog inputs can still be assigned to the USB 3-4 bus while the S/PDIF Assign is enabled, allowing both digital and analog audio to be recorded simultaneously. · S/PDIF Assign LED This LED lights when the S/PDIF input is assigned to the USB 1-2 bus. · Output Level This knob controls the overall output level of the Omega's Line and Headphone outputs. · S/PDIF Lock LED The LED lights when the S/PDIF input has locked in with the Omega. If this LED is not lit, digital signal can not be received from external devices via the S/PDIF input. · Meter Assign This switch assigns which signals (signals assigned to USB 1-2 bus or USB 3-4 bus) are being monitored by the Omega's meter ladder. When the Meter's Clip LEDs light, analog input signals are clipping the A/D converter. Adjust the Mic and Line gain knobs so that the -6 dB yellow LED only lights occasionally. · Headphone Output The Headphone Output accommodates stereo headphones with a 1/4" stereo plug. · Instrument Input Jack This 1/4" jack accepts unbalanced instrument sources such as electric guitar, acoustic guitar with a pickup, and electric bass. The input gain is adjusted using the Line 3 knob on the front panel respectively. When an instrument is plugged in, it disables the Line 3 audio input. · USB LED The USB LED indicates that the Omega is communicating with your computer via USB and audio and MIDI signals can pass in and out of the system. If the USB LED is blinking, the Omega is not 4 OMEGATM The Rear Panel THE REAR PANEL The OMEGA's rear panel offers the following features: · Line In 1-4 These 1/4" inputs can accept both balanced and unbalanced audio sources. The input gain is adjusted using the Line 1-4 knobs on the front panel respectively. · Mic 1-2 Inputs These balanced XLR inputs feature high quality dbx® mic preamps designed specifically for microphone use. The input gain is adjusted using the Mic 1-2 knobs on the front panel respectively. · -20dB Pad The -20dB pad is a resistive attenuator that drops the level coming from the mic input jacks. Its purpose is to give you a way of preventing overload of the preamp when incoming signals become excessive. Another purpose is to change the preamp's mic input into a line input. This means when the · Line Out L/R These outputs support balanced TRS or unbalanced TS 1/4" connections. These outputs can be connected to a mixing board, power amplifier, or another line level input. 5 The Rear Panel pad is on, the net gain of the preamp is 20dB lower than normal. Lexicon Professional® · +48V Switch This switches on the phantom power to the Mic 1 and Mic 2 inputs. [. . . ] You must install the USB drivers after you've made the connection between your computer's USB port and the USB port of the Omega. WINDOWS 2000 Windows 2000-based systems must have the USB drivers installed before making the connection between your computer's USB port and the USB port on the Omega.
