INSTALLATION

Your SM Pro Audio AB8 was carefully packed in the factory and the packaging was de-

signed to protect the unit from rough handling. Nevertheless, we recommend that you

carefully examine the packaging and its contents for any signs of physical damage, which

may have occurred in transit.

If the unit is damaged, please do not return it to us, but notify your dealer and the shipping

company immediately, otherwise claims for damage or replacement may not be granted.

Shipping claims must be made by the consignee.

PLACEMENT

The SM Pro Audio AB8 has an electronic circuit inside as well as isolation transformers.

Be sure that there is enough air space around the unit for cooling. As to avoid overheating,

please do not place the units on high temperature devices such as power amplifiers or

near other units which may have high frequency transmittance such as wireless devices.

Mains voltage

The AB8 can be used with voltages ranging from 100V AC to 250V AC, please make sure

that you have selected the correct voltage range on the back of the unit and that the re-

quired fuse setting is correct as well before switching the unit ON. Any damage occurring

as a result of incorrect voltage selection may not be granted a warranty repair.

2. INTRODUCTION

Using our popular and proven ADAT interface we have created the AB8. Being used by

the majority of audio card and mixing console manufacturers, the ADAT interface presents

a simple way of expanding audio inputs into most pieces of audio equipment made today

including, digital desks, digital snakes, broadcast audio gear and standard desktop audio

interfaces.

The AB8 represents a great way of converting 8 line level inputs to the ADAT format. Ba-

lanced or unbalanced the audio signal travels thru our own high quality transformer iso-

lated inputs and then via a passive attenuation circuit. The signal is then digitally

converted to the ADAT format. A word clock interface is also provided for easily syncing

to external devices.

A great tool for increasing your audio inputs where ADAT enabled products are used.

3. THE DESIGN CONCEPT

3.1 High quality components and design

The philosophy behind SM Pro Audio products guarantees a no-compromise circuit de-

sign and employs the best choice of components.

3.2 Inputs and outputs

All inputs and outputs are secured firmly to the exterior chassis housing. This ensures ro-

bust quality and confidence in performance under all conditions.

4. AB8 FRONT panel

The panel has 8 attenuation controls, 1 power switch and 8 combo connectors.

4.1 Power Switch

Use this switch to switch the AB8 ON or OFF

4.2 Level control

The AB8 uses attenuation to control the level which is being sent first to the Analog to Di-

gital converter and then to the ADAT output. It is NOT a gain control, it can only reduce

the level of the input signal.

4.3 Combo input XLR

The XLR part of the COMBO input connector is a balanced input and as such is set at a

maximum of +4dB 0dBFS equals +22dBu. Connect any balanced equipment to this input.

Note, this is not a preamp, a microphone will probably not yield enough output level to

work with this device.

4.4 Front Panel Combo line input (1/4” 6.5mm Jack)

Use this connector for devices which are not balanced such as standard line level equip-

ment. -10dBv, 0dBFS equals +8dBv (Jack)

4.4 Front Panel Combo line input 4.3 Combo input XLR

4.2 Level control 4.1 Power Switch

5. AB8 Back panel

The back panel has the ADAT optical output, BNC connectors for word clock as well as

the selector switches and power cord connector.

5.1 Word Clock Input

Use this BNC connector when running the AB8 from an external clock source (make sure

you select EXT sync)

5.2 44.1 / 48kHz selector switch

Use this switch to select which sample rate the unit will be running at. Please make sure

the equipment connected to the ADAT output of the AB8 matches this sample rate as well.

5.3 Optical ADAT OUTPUT connector

Connect your optical cable (ADAT FORMAT) to this output connector, the ADAT OPTICAL

cable will transfer all 8 channels on this one cable.

5.4 External / Internal selector switch

Use this switch to select INTernal or EXTernal Word Clock sync, when the unit is being

used as a master, use the INT setting. When you want the unit to be a slave device select

EXT. You can easily see if the unit is working properly by looking into the optical output

connector. If you see a RED LIGHT you know the unit is sending out DATA in the selected

mode.

5.5 Word Clock Output

Use this connector if you want to sync other devices using the AB8’s own internal clock.

6. APPLICATION

6.1 Using the AB8 to convert line level signals to ADAT

Make sure the AB8 is powered and that the ADAT signal is running (red light in the optical

output). Connect several devices (Kb’s, mixer, Mp3 players etc) to the AB8.

If you are using a recording interface, make sure you select EXTERNAL ADAT SYNC in

your master clock selection and connect the AB8 to the ADAT input of your interface. For

digital desks you would also select EXTERNAL ADAT CLOCK as your master.

If you have an external recording device which has WORD CLOCK output you could use

the recording device as the master and then connect both a BNC coaxial cable as well

as the optical cable to the AB8. Make sure you select external WORD CLOCK source on

the AB8. Connect the cable from the WORD CLOCK output of the device to the WORD

CLOCK input of the AB8

Adjust the attenuator on each of the inputs so that you do not overload the signal and

cause distortion.
