HDS-6 Controls
The HDS-6 provides several simple controls and indicators that make it quick and easy for you to get optimum performance with your headphones. First, make sure your console is connected to your HDS-6 (either directly or through your patch bay) and is providing a signal to your HDS-6. The HDS-6 front panel controls are shown in the drawing below. 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.

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 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 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 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: You�ll find it on the HDS-6 rear panel. GROUND LIFT Switch: This rear panel switch 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.

LEVEL SET Control: This small trim pot controls the 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-to-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
