User manual FURMAN HDS6

[. . . ] It provides custom headphone mixes to a number of people in recording and rehearsal environments. The system consists of the rackmount HDS-6 Headphone Distribution System, and one or more Furman HR-6 Personal Headphone Mixers. The HDS-6 distribution system is designed specifically as a low-distortion line driver and power supply for the most critical listening situations. The HDS-6 typically connects to a mixing console and provides both the interface and power to drive a chain of HR-6 mixing stations. [. . . ] Just beneath the heading "SUBMIXES" you'll see four identical groups of controls and indicators ­ one group for each of the HDS-6's four mono channels. See the following page for a more detailed description of the controls. HDS-6/HR-6 HEADPHONE DISTRIBUTION SYSTEM amount of gain the HR-6 applies to the signal from your console before the signal is sent. The control is designed to be adjusted by a small screwdriver to prevent accidental changes of its setting during tracking or playback. The proper setting of this control is accomplished with the help of the "Overload" LED. A white label area is provided for each of the four mono channels to allow you to write down the program source from your console. Use a grease pencil for easy erasability. OVERLOAD Indicators: To get the best signal-toLEVEL SET Control: This small trim pot controls the just some of the time. Also, they should glow at the same intensity. If you notice that the LEDs marked "Left" and "Right" are not glowing at the same intensity, you may need to adjust the output from your console. LINK CABLE REVERSED Indicator: As mentioned noise ratio and maximum headroom, refer to this LED while calibrating your HDS-6's gain controls. If this red LED is glowing constantly, your HDS-6 gain is set too high. Conversely, if this red LED doesn't glow at all, your HDS-6 gain is set too low. What you want to see is the LED glowing occasionally, on the loudest peaks only. MON/EFF MIX Control: This trim-type screwdriver earlier, it is necessary to connect the "Blue" and "Gray" Ethernet cable outputs of the HDS-6 to the corresponding inputs of the first HR-6 in your chain of HR-6 mixers, and to follow the same procedure when daisy-chaining multiple HR-6 mixers. If you accidentally reverse the color-coded cables when connecting, don't worry. The LINK CABLE REVERSED indicator on the HDS-6 will light up to alert you. Simply reconnect any cables that are reversed. POWER Indicator: This front panel LED glows when the HDS-6 is on. POWER Switch: It is on the HDS-6 rear panel. GROUND LIFT Switch: This rear panel switch pot controls the gain for the Left-Right stereo inputs of the HDS-6. Both the Left and Right program sources are affected identically with this control. Two OVERLOAD indicators are also provided for this stereo pair. As with the overload indicators for each of the HDS-6 four mono channels, you'll want to adjust the gain control so that the LEDs marked "Left" and "Right" are glowing takes the audio ground off the chassis ground, which can prevent buzz or hum caused by ground loops. This switch does not affect the AC safety ground of the HDS-6. Under no circumstances should you ever remove the third prong on your HDS-6's AC plug. (To HDS-6 Stereo Inputs) (To Mixer Effects Return) Up to eight HR-6s can be daisy chained depending on the impedence of your headphones. 4 HDS-6/HR-6 HEADPHONE DISTRIBUTION SYSTEM HR-6 CONTROLS Now that you have your HDS-6 connected to your console, and your chain of HR-6 mixing stations is connected to your HDS-6, the fun begins. Here's all you need to know to create a custom headphone mix with an HR-6: SUBMIXES Volume Controls: The front panel of the Each HR-6 also comes with hardware to clamp the HR-6 on a mic stand. The HR-6 also provides erasable white label areas to jot down the signal source for each of its four mono channels.
