Comet Computer DAC User Guide Thank You All of us at EXOGAL would like to say thank you, and congratulations for purchasing the EXOGAL Comet Computer DAC. We sincerely believe that your Comet is an intelligent investment that will bring you many years of musical enjoyment and satisfaction. While every new owner is anxious to begin listening, we encourage you to take a few minutes to read this manual and familiarize yourself with the full capabilities of the EXOGAL Comet.
Comet Computer DAC User Guide Connecting the Comet ! Your EXOGAL Comet Computer DAC uses an external power supply which is designed to work with line voltages from 100VAC to 240VAC, 50/60Hz. The supplied power adapter can accept different sets of prongs to allow it to plug into the wall socket in different countries. Attempting to use a different power supply may damage the unit. Damage caused by improper operation is not covered by warranty.
Comet Computer DAC User Guide Connecting to a Transport or Other Digital Source Avoid allowing static shocks to be applied to the inputs or outputs. To prevent static shocks, touch any grounded surface, such as the EXOGAL Comet chassis, before connecting or removing a cable. It is unlikely that a static shock will damage the unit, but it may cause the EXOGAL Comet circuitry to “lock-up” (see Troubleshooting: Lock-up – page 10).
Comet Computer DAC User Guide Choosing a Digital Input Cable While the EXOGAL Comet supports most commonly accepted transmission formats for digital audio, we recommend using a high quality cable. Contact your EXOGAL retail representative for recommendations.
Comet Computer DAC User Guide Then you will see the EXOGAL Logo with the planets of the galaxy “rotating”. This tells you that the unit is going through it’s startup process: Finally, you will see the main display screen: To understand the Main Screen, you need to understand two symbol areas.
Comet Computer DAC User Guide Selecting an Input Any of the five inputs on the EXOGAL Comet can be selected by pressing the Input Select key on an EXOGAL Remote or on an EXOGAL Smartphone Application. The inputs are selected on a rotating basis in the following order: TOSLINK Analog USB AES/EBU SPDIF Each time the Input key is pressed, the next input is selected. For example, if TOSLINK is currently selected, pressing the Input key on the remote control will advance to the Analog and so on.
Comet Computer DAC User Guide Volume and Mute Modes Adjusting the Volume Whenever the Volume Up or Volume Down keys on a remote control or in an EXOGAL Smartphone Application are pressed, the volume on both channels will be increased or decreased by an increment of 1 on the display screen. The range of the volume display is from 0 to 100, with each step representing 0.5dB change in volume. During normal operation, the numbers on the Main Screen will increase or decrease as the volume is raised or lowered.
Comet Computer DAC User Guide The EXOGAL Comet has mute relay connected between the positive and negative outputs. When this relay is engaged, it connects the positive output to the negative output, reducing the output to zero. This relay, which produces an audible click when it engages or disengages, is not in the music signal path.
Comet Computer DAC User Guide EXONet The EXONET input and output connectors are a proprietary interface that will allow external EXOGAL expansion products to be added to the Comet. They allow for a high speed digital interface, with control. They are not HDMI compliant, but should not cause damage if they are mistakenly attached to a HDMI interface. USB Charger The USB charger output is compliant with most common charging standards.
Comet Computer DAC User Guide Frequently Asked Questions Should I Use a Balanced or Unbalanced Connection? If your amplifier has a true balanced input, we recommend you use the balanced analog output from your EXOGAL Comet. All things being equal, properly implemented balanced (also called differential) circuitry sounds better than unbalanced circuitry. The EXOGAL Comet is a true balanced design.
Comet Computer DAC User Guide Should I Leave the EXOGAL Comet with the Power On? The EXOGAL Comet is designed to be left with the power on with no harm or wear to the unit. When the Comet is placed in MUTE it will enter Standby mode after approximately 30 minutes, which reduces power consumption dramatically. Leaving the power on allows the circuitry to remain in thermally stable, which provides better performance and longer life.
Comet Computer DAC User Guide Safety Precautions ! IMPORTANT SAFETY PRECAUTIONS! To get the best performance from your EXOGAL Comet, and for your own safety, please read and follow these important safety instructions. 1 Before operating the EXOGAL Comet please read all operating and safety instructions. 2 Never place the EXOGAL Comet near heat sources such as radiators, fireplaces, stove, or other appliances that produce heat.
