Introduction

Thank you for your purchase of a Furman HDS-6 Headphone

Distribution System and HR-6 Personal Headphone Mixer – and congratulations

on your choice. We based this system on our own experiences with major

recording projects and studios. You now own a headphone system that will make

all of your sessions flow more smoothly.

Please read this manual before using your HDS-6/HR-6 system.

Features

•Every artist in the studio can have a personalized headphone mix.

•It’s perfect for tracking, overdubbing and rehearsal sessions.

•The HDS-6 rackmount distribution system quickly and easily connects

to any studio console or patch bay. It provides the interface to drive a

chain of HR-6 personal headphone mixers.

•Each HR-6 remote mixing station provides each musician five volume

controls: four monaural (for mixer channels or busses), one for the

stereo mix or stereo effects mix, and a button to mute all but the stereo

channel.

•Inexpensive Ethernet computer cables are used to link the HDS-6 to

HR-6s, and HR-6 mixing stations to other HR-6s.

•The HDS-6 also features an On-Off switch, power-on LED and a Signal

Overload LED for each channel. Other features include an LED to

indicate Link Cables Reversed, Ground Lift switch, signal inputs and

outputs, and HR-6 link connectors.

Description

The new Furman Headphone Distribution System is easy to set up, and

makes your music sound great. 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. Since the HDS-6

provides signal, power and ground to the HR-6 remote mixers, you don’t have to

worry about locating your HR-6 remote mixing stations near an AC power outlet.

One HR-6 mixing station with mic stand clamp is included with

purchase of the HDS-6; additional HR-6 remote mixers are available separately.

Linking the distribution unit and remote mixers is as simple as plugging in

standard, inexpensive Ethernet cables. One pair of cables is included with your

HDS-6.

Up to eight HR-6 mixing stations can be linked to the HDS-6, depending on

headphone type and impedance, and multiple HR-6s are easily daisy-chained. You

can even plug two headphones into one HR-6. Please note that if you do, both

headphones should be the same brand and model – if they’re not, their listening

levels probably won’t be the same. Every musician plugged into an HR-6 mixing

station can create his or her own custom mix without assistance from the engineer in

the control room.

The HR-6 mixing station is compact, lightweight and designed to clamp

onto a mic stand. It provides a volume control for each of its four mono channels,

and a fifth volume control -- assigned to both the left and right -- inputs the stereo

channel. The stereo pot will most often be used for the main control room mix, or

for stereo effects from the console. You can instead choose to use the left and right

inputs on the HDS-6 for two more mixer channels or busses if you wish. Just

remember that the listening level of both inputs will be controlled by only one

volume control.

The HR-6 personal mixer provides another very useful feature: the

“Submixes Included/Excluded” button. This button mutes the four monaural

channels. This means every HR-6 user can hear the stereo source only, without

having to alter the HR-6’s four monaural settings. This is very helpful when all

musicians wish to hear playback of a control-room mix.

Connecting the HDS-6

Since the HDS-6/HR-6 system will be used most often for studio tracking

and playback, it is designed to be direct-out patchable with mixing consoles. If your

system has a patch bay, we suggest you connect the HDS-6 to it instead of your

console.

The HDS-6 has balanced TRS inputs, so if your outputs are balanced, that’s

even better. But standard ¼” phone-plug cables will work fine too. Just connect the

direct-out of a mixer channel strip or buss to an input of the HDS-6, and connect any

stereo output of the mixer to the stereo inputs on the HDS-6. Remember, you can

instead use the HDS-6 Left-Right stereo inputs for two more mono channels or

busses from your console.

Please see the drawings on the next page and on pages 5-6.

Connecting the HR-6

The HDS-6 connects to an HR-6 with two standard (10 base-T UTP)

Ethernet cables. Two cables, coded blue and gray and each 25 feet in length, come

with your HDS-6; additional cables are available from Furman. You will need a pair

of these cables in order to connect the HDS-6 to an HR-6, and additional pairs to

connect multiple HR-6s.

Again, please see the drawings on the next page and on pages 5-6.

Linking HDS-6 to HR-6s

The HDS-6 links to your mixer or patch bay via the six TRS ¼” phone

jacks on the right side of the HDS-6 rear panel, as shown on the drawing below.

You’ll have four mono jacks for the signals coming from the direct channel out

of the busses of your mixer, and two more jacks for the Left and Right stereo

inputs from your mixer (or two more mono signals).

The left side of the HDS-6 rear panel provides two Ethernet cable connectors,

labeled “Blue” and “Gray,” to link the HDS-6 to the first HR-6 mixer in your chain.

The HR-6 mixing station, shown below, links to your HDS-6 with the pair

of Ethernet cables you just connected to your HDS-6. Make sure you connect the

“Blue” and “Gray” Ethernet outputs of the HDS-6 to the “Blue” and “Gray” inputs

of the first HR-6 mixer in your chain. When daisy-chaining HR-6 mixers, be sure to

connect the “Blue” and “Gray” outputs of one HR-6 to the “Blue” and “Gray” inputs

of the next one.

HDS-6/HR-6 HEADPHONE DISTRIBUTION SYSTEM

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.

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

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.

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 HR-6 mixer provides one

volume control for each of the four mono channels arriving at the HR-6 from your

console and HDS-6 Distribution System.

MON/EFF Volume Control: This single control simultaneously adjusts the level of the

stereo main mix (or stereo effects returns, or two more channel strips of busses)

arriving at the HR-6 from your console through the HDS-6. Remember: If you use the

HDS-6’s Left-Right inputs to accommodate two or more console channels or busses

instead of one stereo signal, the volume levels of both console channels or busses will

be adjusted by this control. These two inputs will not be individually adjustable for

loudness as the four mono channels are.

SUBMIXES “INCLUDED/EXCLUDED” Button: This feature allows each musician

to hear, for example, only the main mix coming from the control room. The button

mutes the four mono controls, allowing each HR-6 user to hear stereo source only,

without having to turn down the HR-6’s four mono volume knobs.

HEADPHONE OUTPUTS: The HR-6 provides two ¼” stereo headphone jacks. You

may plug two headphones into one HR-6, but unless both are the same brand and

model, one headphone is likely to not be as loud as the other.

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. Use a grease pencil for easy erasability.

LINK CABLE REVERSED Indicator: As mentioned earlier, you need to connect the

“Blue” and “Gray” Ethernet cable outputs of the HDS-6 to the corresponding inputs of

the first HR-6. These corresponding inputs must remain consistent with each

subsequent HR-6 mixer. If you accidentally reverse the color-coded cables, don’t

worry. The LINK CABLE REVERSED indicator on the lower left corner of the HR-6

will alert you. Simply reconnect any cables that are reversed.
