Introduction

Thank you for your purchase of the Balanced Audio Technology VK-D5 CD player.

Please read this owner's manual to obtain the full benefit of the VK-D5 in your system. It will

provide you with the needed safety information and operating procedures for this exceptional

unit.

Package Contents

Included in the box should be the following:

Description Quantity

VK-D5 CD Player 1

Power Cord 1

Spare Fuses 2

Torx Wrench (T-10) 1

Spare Top Cover Screws 5

User’s Manual 1

VK-R2 Remote Control 1

Save all the packaging material in a safe dry area for the unlikely event that you

WARNINGS:

To prevent the possibility of serious injury, electrical shock or fire:

DO NOT operate with the cover removed.

DO NOT expose to rain or moisture.

DO NOT defeat the ground power-plug.

DO NOT replace fuse with anything other than the same type and rating as supplied by the factory.

Reseating Tubes

Normally, reseating tubes upon delivery is not required. However, if any tubes have

noticeably drifted out of position due to high transportation stress, it will be advisable to

reseat the tubes. Use the supplied Torx wrench to remove the top cover. Reseat the tubes

in their sockets and reinstall the top cover.

NOTE: When using the Torx wrench, make sure it is fully inserted so that the screw head

is not stripped.

Physical Placement

It is recommended that you provide for at least 6" of free space around the unit for proper

ventilation.

Mount the unit on a hard surface with proper ventilation underneath.

Do not stack the VK-D5 CD player on top of other units, nor vice versa.

Connecting the VK-D5 to Your System

Balanced Components

Use balanced XLR interconnects. All input and output connectors are clearly marked on the

back panel.

Note: The VK-D5 XLR connectors are wired as follows:

Pin 1: common/shield

Pin 2: positive

Pin 3: negative

Single-Ended Components

Single-ended components have RCA connectors. The VK-D5 CD player allows

direct connection to a single-ended preamplifier using the back-panel mounted RCA jacks.

PC Board Configuration Jumpers

The VK-D5 is equipped with the following PC board mounted jumpers that can be used to

optimize its characteristics for particular user requirements.

Digital Output Enable-Disable (Jumper JP1)

This jumper is located between the two ribbon cables near the front of the unit. It allows the

user to disable the VK-D5 digital output (by moving the jumper into its Disable position) when

such output is not required or not used. Simply move the jumper back to EN to make the

digital output functional again. All units are shipped from the factory with the digital port

Enabled.

Operating the VK-D5

Turning the VK-D5 On:

The master power switch for the VK-D5 is located on the back-panel above the IEC power

connector.

When you turn the VK-D5 On, it will automatically go through a gentle power-on sequence.

This sequence takes 50 seconds, during which time the blue Standby LED will be flashing.

After this time the Standby LED will turn OFF and the unit is ready to play.

Placing the VK-D5 in and out of Standby Mode:

The VK-D5 features a standby switch in the right-most position on the front panel.

When you are finished playing music, simply place the VK-D5 in standby mode by pressing

this switch. The blue Standby LED will turn ON. To turn on the unit, simply press the

switch again and the unit will automatically go through the standard power-up sequence.

When the blue LED stops flashing, you can play music.

Phase Inversion Switch

The VK-D5 features a front-panel phase inversion switch. By pressing this switch, you can

compensate for recordings that are made “out of phase”. The blue LED ON indicates the

inverted phase condition.

Front-panel CD player controls

The front panel CD player controls for the VK-D5 follow industry standard conventions for

CD playback and should be used accordingly.

Remote control functions

The VK-D5 CD player is supplied with the VK-R2 infrared remote control transmitter that

allows the user to control the volume of Balanced Audio Technology preamplifiers in addition

to providing complete control over the VK-D5 CD player. This combined functionality

eliminates the need for two separate remote controls in a system where the VK-D5 is paired

with the BAT i-series preamplifiers.

The buttons on the VK-R2 remote control are arranged in two groups. The upper group

controls the CD player. The lower four buttons on the transmitter control the volume setting of

the BAT i-series preamplifiers.

CD Player Controls

Basic Remote CD Mechanism Controls

The basic CD control function use the standard symbols for the CD player functions. They are

arranged on the VK-R2 remote control transmitter in three rows as follows:

[Rewind] [Fast Forward]

[Previous] [Next]

[Stop] [Pause] [Play]

[PHASE] Reversal Function

The button that controls the phase reversal function is located right above the basic CD

controls. Pressing this button will reverse the signal absolute polarity. The front panel Blue

LED will indicate the polarity inversion.

Programming Functions:

The buttons associated with the programming functions of the CD player are located in the top

section of the VK-R2 remote control. They work as follows:

[PROGRAM]

To program the sequence of tracks from the same CD:

1. Put the player in [STOP] mode

2. Press the first selection number (for example press the button [5] for the track #5)

3. Press the [PROGRAM] button

4. Press the next selection number

5. Press the [PROGRAM] button

6. Continue this routine until the complete sequence of tracks is entered

7. Press the [PLAY] button to start the programmed sequence

[REPEAT]

This function allows the user to repeat either the particular track on the CD, or a complete CD.

It works as follows:

1. Press the [REPEAT] button once while playing the CD. The “Repeat” legend will

appear on the VK-D5 display. The unit will now continuously play the complete CD,

until the [STOP] button is pressed..

2. Pressing the [REPEAT] button for the second time will change the display to

“Repeat 1”, indicating that the current CD track will be played repeatedly.

3. Pressing the [REPEAT] button for the third time will clear this function.

[SHUFFLE]

Pressing this button will put the VK-D5 CD player into a random play mode. The tracks of the

CD will be played in random order until the [STOP] button is pressed.

[A/B]

This function allows the user to continuously play the selected section of any CD track. The

selected segment is marked by two pointers: A (beginning) and B (the end of segment). To

activate this function do the following:

1. Start the desired track in normal [PLAY] mode.

2. At the beginning of the desired segment, press the [A/B] button. The “A” symbol will

appear on the VK-D5 display.

3. At the end of the desired segment, press the [A/B] button again. The A-B symbol will

now be displayed by the CD player and the selected segment will now be repeated

continuously until the [STOP] button is pressed.

[TIME]

Pressing the [TIME] button on your VK-R2 remote control transmitter will change the VK-D5

time display mode in the following sequence:

1. Elapsed time from the beginning of the current track

2. Total time from the beginning of the CD

3. Remaining time to the end of the CD

Preamplifier Controls

The four buttons in the lower section of the VK-R2 remote transmitter control the volume of

the BAT i-series preamplifiers.

NOTE: The VK-R2 remote transmitter will only control the BAT i-series preamplifiers that are

equipped with the factory remote control option.

The functions of the preamplifier control buttons are identical to those of the similarly marked

buttons on the VK-R1 preamplifier remote control transmitter.

1. Volume Up and Volume Down control

2. Mute function

3. Fade Down/Fade Up function

The following describes these functions.

Volume Up and Down

These two buttons are programmed with variable speed volume change profiles. The rate of

volume change will be slow upon initial pressing of the Volume [UP] or [DOWN] buttons.

Holding the button depressed will cause the rate of change to accelerate, allowing for more flexible

control when large changes in volume are required.

Mute

Pressing this button will cause the MUTE function in the preamplifier to toggle between ON and

OFF states. The Mute LED on the preamplifier display will reflect the status of the Mute circuit.

Fade

Pressing the FADE button on the VK-R2 remote control will cause the volume to smoothly decay

over the period of several seconds. This allows for a gradual reduction in volume, as opposed to

the instantaneous MUTE function. This can be particularly useful during the presentation or

demonstration of your equipment. When the [FADE] button is pressed, the volume will go down

all the way to zero (00 on display, unit in Mute).

Pressing the Fade button again will cause the volume to ramp up and return to its initial value.

Fuse Protection:

A blown fuse in the VK-D5 is an indication of a serious problem. If a replacement fuse

fails as well, no further attempts should be undertaken. Please contact the factory for

professional service.

The proper fuse ratings are as follows:

For 100-120 VAC Units: 2A 250V Slow Blow

For 200-240 VAC Units: 1.0A 250V Slow Blow

Servicing

The Balanced Audio Technology VK-D5 should require no service other than changing

tubes to maintain its high performance. The six vacuum tubes used in the VK-D5 are

quality 6922s rated for approximately 5000 hours of use. Please direct any further service

inquiries to the factory.

Cleaning

To remove dust, occasionally wipe the front and top surfaces of your VK-D5 with a damp

soft cloth. If fingerprints appear, you may use a mild, non-alkaline soap solution. Do not

use abrasive cleaners, as they may damage the fine finish of the unit.

Factory supplied fuses should be only replaced with the same type and rating parts.
