The HDVA 600 headphone amplifier

The state-of-the-art HDVA 600 headphone amplifier allows you to fully

exploit the potential of your high-end headphones. The HDVA 600s con-

sistently symmetrical signal processing and extremely low harmonic dis-

tortion ensures an unadulterated and perfect music enjoyment.

The HDVA 600s output circuitry is designed for use with up to four

dynamic headphones. Consistent wiring and the use of XLR-4 sockets

ensures an excellent channel separation.

You can connect digital audio sources such as CD, DVD and Blu-Rayplayers

and analog audio sources such as as tuners, open reel machines and turn-

tables with a corresponding preamplifier to the HDVA 600. Digital sources

are connected via their analog outputs. The input selection rotary switch

allows you to switch between the connected audio sources.

The headphone amplifier and the Sennheiser HD 800, HD 700 and HD 650

high-end headphones are optimally matched with regard to technology,

design and performance characteristics and fulfil the demands of the most

discerning audiophile.

Features

Symmetrical signal processing with exact signal transmission over the

entire frequency spectrum and extremely low harmonic distortion

Can be used with up to four dynamic headphones

122 dB dynamic range, wide bandwidth and high transient response

due to short signal paths

Balanced XLR-4 sockets and high-quality (6.35 mm) jack sockets

for connection of headphones

Connection possibilities:

analog inputs: balanced XLR-3, unbalanced RCA

analog output: balanced XLR-3

Putting the HDVA 600 into operation

Setting up the headphone amplifier

Place the headphone amplifier on a flat, horizontal surface.

Ensure sufficient ventilation. The headphone amplifier generates heat

which is dissipated through the housing.

Connecting the headphone amplifier to audio sources

You can connect several audio sources to the headphone amplifier and

switch between these connected sources using the input selection rotary

switch.

Switch your audio source off.

Select a suitable high-quality connection cable for your audio source

and, if necessary, a suitable adapter. Please observe the maximum rec-

ommended cable length L max.

Proceed as described in the corresponding chapter.

CAUTION

Risk of staining of furniture surfaces!

Varnish or furniture polish may degrade the feet of the product, which

could stain your furniture.

Do not place the product on delicate surfaces; if necessary, use a non-

slip pad under the product.

Integrating the headphone amplifier into an existing connection between devices (daisy-chaining the audio signal)

You can integrate the HDVA 600 into an existing connection between your

audio source and an additional device. By way of example of an amplifier

as an additional device, this chapter describes how to integrate the

HDVA 600 into an existing connection.

Pull out the plug of the connection cable from the input IN on the

amplifier.

Connect this plug to a suitable input IN on the HDVA 600 (see page 7).

Connect a second connection cable to the input IN on the amplifier and

to the output OUT on the HDVA 600.

Use the input selection rotary switch (see page 6) to select the corre-

sponding audio source.

Connecting the headphone amplifier to the mains

Connect the mains cable to the mains socket and a wall socket.

To disconnect the headphone amplifier from the mains:

Unplug the mains cable from the wall socket.

CAUTION

Danger of damage to the product!

If you use an unsuitable power supply, this can cause damage to the

product.

Use a suitable mains cable to connect the product to the mains (100 to

240 V AC, 50 or 60 Hz).

Using the HDVA 600

Using the HDVA 600

Switching the HDVA 600 on/off

Press the on/off button.

When the headphone amplifier is switched on, the on/off button is

backlit. When you switch off the headphone amplifier, the backlighting

of the on/off button goes off.

Connecting headphones

The HDVA 600 features 2 balanced XLR-4 sockets and 2 unbalanced

(6.35 mm) jack sockets for connecting up to 4 headphones. We recom-

mend using high-impedance headphones for an optimal listening

experience.

Connect one or several pairs of headphones.

WARNING

Hearing damage due to high volumes!

Listening at high volume levels for long periods can lead to perma-

nent hearing defects.

Set the volume to a low level before putting on the headphones

(see page 13).

Do not continuously expose yourself to high volumes.

Selecting an audio source

Use the input selection rotary switch to select your connected audio

source.

WARNING

Danger of hearing damage!

In order to protect your hearing, before switching to a different

audio source, first set the volume on the headphone amplifier to

a low level. Different signal sources and different listening material

(e.g. different pieces of music on different CDs) can have widely

varying signal levels. In the case where you switch to a higher level

signal source from a lower one without first reducing the volume

level this can lead to high volume levels in the headphones and

could damage your hearing.

Set the volume on the headphone amplifier to a low level (see

page 13) before switching to a different audio source.

Adjusting the signal level of the RCA input

In order to optimally set the gain of the headphone amplifier, you can use

the input attenuation rotary switch (-GAIN+) to adjust the signal level of

the RCA input.

Turn the input attenuation rotary switch (-GAIN+) towards the

+ sign: if the signal is too low or

- sign : if the signal is overmodulated.

Adjusting the volume

Use the volume control to adjust the volume.
