The DR16pro is designed to be used in a standard household environment. Power requirements for electrical equipment vary from area to area. Please ensure that your DR16pro meets the power requirements in your area. If in doubt, consult a qualified electrician or AKAI professional dealer.

120VAC @ 60Hz for USA and Canada 220-230/240VAC @ 50Hz for Europe 240VAC @ 50Hz for Australia

PROTECTING YOURSELF AND THE DR16pro

Never touch the AC plug with wet hands.

•

Always disconnect the DR16pro from the power supply by pulling on the plug, not the cord.

•

Allow only an AKAI professional dealer or qualified professional engineer to repair or reas-

•

semble the DR16pro. Apart from voiding the warranty, unauthorized engineers might touch live internal parts and receive a serious electric shock.

Do not put, or allow anyone to put any object, especially metal objects, into the DR16pro.

•

Use only a household AC power supply. Never use a DC power supply.

•

If water or any other liquid is spilled into or onto the DR16pro, disconnect the power, and call

•

your dealer. Make sure that the unit is well-ventilated, and away from direct sunlight.

•

To avoid damage to internal circuitry, as well as the external finish, keep the DR16pro away

•

from sources of direct heat (stoves, radiators, etc.). Avoid using aerosol insecticides, etc. near the DR16pro. They may damage the surface, and

•

may ignite. Do not use denaturated alcohol, thinner or similar chemicals to clean the DR16pro. They will

•

damage the finish. Modification of this equipment is dangerous, and can result in the functions of the DR16pro

•

being impaired. Never attempt to modify the equipment in any way. In order to assure optimum performance of your DR16pro, select the setup location carefully,

•

and make sure the equipment is used properly. Avoid setting up the DR16pro in the following locations:

1. In a humid or dusty environment

2. In a room with poor ventilation

3. On a surface which is not horizontal

4. Inside a vehicle such as a car, where it will be subject to vibration

5. In an extremely hot or cold environment

Page ii

Precautions When Using the Installed Hard Disk Drive

1. The hard disk drive has extremely high precision and is vulnerable to shock and vibration. If transporting the DR16pro by either land or air, we recommend packing it in a shell-shaped case lined with urethane rubber which meets ATA specifications.

2. Make sure the DR16pro is used in the horizontal position. Do not set it on end or tilt it when using it.

3. If the DR16pro is moved from a cold location to a warm one, or if the temperature has been raised suddenly, condensation may form inside the DR16pro. If it is impossible to avoid conditions like these, let the DR16pro sit for at least an hour in the new location before using it.

4. When setting up the DR16pro, make sure the ventilation opening is not blocked. Also, if using the DR16pro in a rack that contains other equipment, make sure sufficient ventilation space is assured on all sides (approx. 44 mm of space between the DR16pro and any equipment mounted above or below it in the rack).

Introduction

Description of Signal Flow

Input

A signal input to the ANALOG INPUT channels 1 to 16 passes through the gain switches (HIGH, MID, LOW) and the GAIN controls. The signal is then converted to digital. Alternatively, pressing the DIGI key will select DIGIT AL INPUT for channels 1 to 8 from the optional Digital Audio Interface (eg. ADAT or AES/EBU).

After digital conversion, the signal goes to the INPUT SELECT switches and then to the hard disk for recording.

At the INPUT SELECT switches, input channels 1 to 8 usually correspond to hard disk tracks 1 to 8 and tracks 9 to 16. However, you can assign any input channel to any hard disk track. You can also select the BUS L and BUS R signals as inputs or the built-in stereo AES or S/PDIF inputs, DIN L and DIN R.

Press the appropriate TRACK REC keys to record data to the hard disk tracks. For Analog inputs, you need to set the recording levels with the GAIN controls. Then press the Play and REC keys to record.

Output

On playback, the signal from the hard disk tracks passes through the CHANNEL ON keys 1 to 16 and into the TRACK MIX section of the mixer. In addition, the signal is sent to the individual ANALOG OUTPUT channels 1 to 16. Unlike the inputs, these output channels are fixed to the corresponding hard disk tracks.

TRACK MIX

In the TRACK MIX section, the signal passes through the equalizer (if the optional digital EQ board is installed), channel level, pan, and effects send. It is then sent to the MASTER LEVEL where it is output in digital through the DIGITAL I/O - MASTER OUT or converted to analog and then to the MASTER L/R or PHONES outputs. The signal is also sent to the SEND and BUS channels. On the SEND channels, it is converted to analog and sent to the SEND 1/L-2/R outputs. It only appears on the BUS channels if the BUS ON switch is selected.

Using the BUS channels allows you to carry out a digital bounce-down recording (ping-pong) inside the DR16pro with very little deterioration in tonal quality.

1) POWER switch

The rocker part of the power switch is recessed in the ON position to prevent accidental

power off.

2) Peak Level meters

These 20-segment FLD (Fluorescent Light Display) bargraphs with peak hold indicate the

playback and source levels. There are sixteen track level indicators that also indicate the

send, bus routing, and stereo master levels. The bargraphs are used to display channel pa-

rameter settings when the DR16pro is in Mix Mode.

Note: These meters are after the A/D converters in the signal path. Therefore when the amber 0 dB (Peak) FLD segment lights, it indicates digital distortion. You should adjust the levels so this never occurs.

3) METER key

This key toggles the level meter indicator between channel and master. Normally, the level

meter shows the level of each track. Pressing the METER key changes tracks 11-16 indica-

tors to send, bus, and master level indicators.

4) DIGI(D IN) key

This key selects digital inputs for input channels 1 – 8 from the optional ADAT or AES/EBU

digital audio interface. (Select the XLR or the RCA/phono connectors with the DIGI(D IN) sub-

menu function.) See “Digital Inputs” on page 33.

This key is also used for selecting either the XLR or RCA connector (DIN-L / DIN-R).

5) CHANNEL ON keys 1/9 ~ 8/16

These keys allow you to select channels for monitoring. See “Track Number Limitations” on

page 42. When you are using the Mix Mode, these keys select the channel you want to edit.

Also see “Selecting Mix Mode” on page 61.

6) TRACK REC(INPUT SELECT) keys 1/9 ~ 8/16

These keys are used to arm tracks for recording (“Arming Tracks” on page 38) or to select

auxiliary inputs (“Setting an Auxiliary Input” on page 64.) A flashing key indicates that a track

is armed for recording, and a lit key indicates recording in progress. Assign the input channel

for each track using the TRACK REC (INPUT SELECT) sub-menu function (“Selecting the

Input Channels” on page 35).

7) RESET key

This key is used to reset the relative time to zero. If it is pressed while an absolute time is

displayed, relative time will be selected automatically, just like pressing the ABS/REL key.

8) ABS/REL(OFFSET) key

This key switches the display between absolute time and relative time. Absolute time starts at

zero, cannot be changed, and works as the base time for relative time. When synchronizing

using SMPTE timecode, the relative mode can be used to set synchronization offsets.

Set the offset for relative time with the ABS/REL(OFFSET) sub-menu function.

9) Time and Status display

This custom FLD (Fluorescent Light Display) shows recording time information and mes-

sages indicating the system status.

The top row of nine 7-segment digits display time, either absolute or relative. It may also be

switched to show bars, beats, and clocks.

The bottom row of 14-segment digits display status, sub-menu, and error messages. Also in

this display, the current mode is displayed.

The “BUSY” indicator at the bottom of the display shows hard disk activity . Beside it, a row of

small dots show activity for each of the 16 tracks and indicate that data exists on the track at

the current position.

10) LOCATE key

This key is used to enter locate time values. See “Locate Functions” on page 77 and “Speci-

fying the “in” Point and “out” Point” on page 26.

while recording and want to return to the previous recording. Likewise, when editing you can

compare the material before and after an edit. See “Recording Undo” on page 44 and “Undo-

ing an Edit” on page 85.

12) JOG/SHUTTLE control

The inner JOG wheel allows you to locate while listening to a recording. Playback speed is

determined by how fast you turn the wheel. Turn it counterclockwise to review and clockwise

to preview. The ef fect is similar to reel-rocking on an analog tape recorder — you can use it to

identify edit points precisely. In certain modes such as MIX, SONG and SUB-MENU, this

wheel is also used for data entry. Turn it counterclockwise to decrease values and clockwise

to increase them.

Like the JOG wheel, the outer SHUTTLE control also allows you to locate while listening to a

recording. The playback speed is determined by the angle at which you hold the control. Turn

it counterclockwise to review and clockwise to preview. The SHUTTLE control is also used to

move the cursor (input point) when setting certain parameter values. See “Cursor” on page

25.

13) FINE key

5) AKAINET connection and TERMINATOR switch

This BNC connector is used to connect the DR16pro to other DR16pros or to remote control-

lers such as the RE32. Multiple units can be connected together by chaining the AKAINET

BNC connectors using standard Ethernet BNC cables and ‘T’ pieces. It is essential that the

first and last units in the chain are terminated either by switching the TERM switch to the ON

position or by using an external 50 ohm terminator.

Note:

The AKAINET interface used in the DR16pro is 10-Base-2 Ethernet. There are certain rules that must be adhered to when setting up the system to ensure reliable operation:

• All cables must be 50 ohm impedance

• There should be a maximum of 185m of cable in the system between the first and last nodes.

• There should be at least 0.5m of cable between each node

6) EXPANSION socket

For connection to the Akai MT8 Mix Tab or RC15 remote control.

7) TERM switch

This switch selects 75Ω termination for the SYNC connection. When a video signal is connected, this switch must be set to ON.
