1. SAFETY PRECAUTIONS

Be sure to read the instructions in this section carefully before use.

Make sure to observe the instructions in this manual as the conventions of safety symbols and messages regarded as very important precautions are included.

We also recommend you keep this instruction manual handy for future reference.

Safety Symbol and Message Conventions

Safety symbols and messages described below are used in this manual to prevent bodily injury and property damage which could result from mishandling. Before operating your product, read this manual first and understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.

WARNING

CAUTION

Indicates a potentially hazardous situation which, if mishandled, could result in death or serious personal injury.

Indicates a potentially hazardous situation which, if mishandled, could result in moderate or minor personal injury, and/or property damage.

WARNING

CAUTION

When Installing the Unit

Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as doing so may result in fire or electric shock.

Use the unit only with the voltage specified on the unit. Using a voltage higher than that which is specified may result in fire or electric shock.

Do not cut, kink, otherwise damage nor modify the power supply cord. In addition, avoid using the power cord in close proximity to heaters, and never place heavy objects -- including the unit itself -- on the power cord, as doing so may result in fire or electric shock.

When the Unit is in Use

Should the following irregularity be found during use, immediately switch off the power, disconnect the power supply plug from the AC outlet and contact your nearest TOA dealer. Make no further attempt to operate the unit in this condition as this may cause fire or electric shock.

·If you detect smoke or a strange smell coming from the unit.

·If water or any metallic object gets into the unit

·If the unit falls, or the unit case breaks

·If the power supply cord is damaged (exposure of the core, disconnection, etc.)

·If it is malfunctioning (no tone sounds.)

To prevent a fire or electric shock, never open nor remove the unit case as there are high voltage components inside the unit. Refer all servicing to your nearest TOA dealer.

Do not place cups, bowls, or other containers of liquid or metallic objects on top of the unit. If they accidentally spill into the unit, this may cause a fire or electric shock.

When Installing the Unit

Never plug in nor remove the power supply plug with wet hands, as doing so may cause electric shock.

When unplugging the power supply cord, be sure to grasp the power supply plug; never pull on the cord itself. Operating the unit with a damaged power supply cord may cause a fire or electric shock.

Do not block the fan exhaust vent on the unit's rear and the ventilation slots on the bottom. Doing so may cause heat to build up inside the unit and result in fire.

Avoid installing the unit in humid or dusty locations, in locations exposed to the direct sunlight, near the heaters, or in locations generating sooty smoke or steam as doing otherwise may result in fire or electric shock.

When installing the unit in an equipment rack, observe the following instructions. Failure to do so may result in fire or personal injury.

·Install the rack on a solid and stable surface. Then, secure it with anchor bolts or make other appropriate arrangements to prevent it from falling down or moving.

·Use the screws supplied with the unit to mount on TOA's rack.

·The AC outlet to which the unit's AC power cable is connected must have allowable current capacity over the unit's current consumption.

When the Unit is in Use

Switch off the power, and unplug the power supply plug from the AC outlet for safety purposes when cleaning or leaving the unit unused for 10 days or more. Doing otherwise may cause a fire or electric shock.

2. GENERAL DESCRIPTION

TOA's D-901 is a 19-inch rack-mounted (3U high) digital mixer configured with 12 inputs, 8 buses, and 8 outputs. It features signal processing functions necessary for sound systems such as feedback suppression and auto-mixing. All functional parameters can be set at the unit*. Settings can be stored in the unit's internal memory as "preset memory" and can be recalled using the front panel-mounted operation keys.

*Can also be set at a PC using the setting software, which can be downloaded from our website "http://www.toa-products.com/international/".

3. FEATURES

Acoustic feedback can be suppressed through simple operation.

Auto-Mixing functions (Ducker*1 and NOM Attenuation*2) automatically adjust the input signal volume.

Signals are digitally processed, ensuring high-accuracy sound parameter settings.

All settings can be performed at the unit using the LCD screen and setting keys and knobs located on the front panel. The settings can also be made at a PC using the dedicated software.

Modular construction permits flexible configuration of inputs and outputs, from 2-IN/4-OUT to 12-IN/8-OUT systems.

Up to 16 preset patterns can be stored in memory, which can be easily recalled from either the unit or connected external equipment.

An RS-232C port permits remote control of the unit using an AMX or Crestron controller, or similar external equipment. The control protocol is available for download at our website http://www.toaproducts.com/international/.

A protect function prevents accidental changes of front panel key settings.

The use of an optional D-981 or D-983 Remote Control Module, or an optional D-984VC VCA Control Module permits easy remote operation of volume control and preset memory recall.

The use of an optional D-984VC VCA Control Module permits the sound volume to be adjusted from remote locations using the faders or volume controls.

*1 Automatically adjusts all channel gains in response to input signal level. (Refer to p. 38.)

*2 Automatically adjusts the input gain of open microphones corresponding to the number of open microphones in the system. (Refer to p. 39.)

4. HANDLING PRECAUTIONS

Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

Use the unit in locations where the temperature is between +5 to +40 °C (no condensation) and the humidity is less than 90%.

The D-901 is a precision audio component. To prevent failure, avoid locations where the unit may be exposed to strong shocks or vibrations.

To clean, be sure to first switch off the power, then wipe with a dry cloth. When extremely dirty, use a soft cloth dampened in neutral detergent. Never use benzene, thinner or chemically-treated towels, which may damage the unit's finish.

5.2. Optional Modules

Notes

Make sure that the power is switched OFF before attaching or detaching modules.

To avoid failures due to static electricity, do not touch the parts or terminals on the circuit board of both the unit and module.

Ensure that the module is installed and secured with screws in the correct position.

Cover idle slots with the blank panels attached to the unit as shipped by the factory.

Two silver slotted screws at the top and bottom of the front panel are handles used for module detachment. Never rotate them because they do not function as screws.

6. SETTING BASICS

6.1. Setting Procedures

The D-901's functions need to be set using the front-mounted keys and knob according to scenes of use. After connecting all external equipment, check the following, then follow the procedures below to set each of the unit's functions.

Check to be sure that

The required modules are correctly inserted.

The power supply is correctly connected.

The power indicator lights when the power switch is turned on.

Step 1. Set which input channel signal is transmitted to which output channel.

Because the factory default setting is made so that each input (1 – 12) is assigned to all outputs (1

– 8) via the Microphone Bus*, when a microphone, or CD player or other music player is connected to an input, its signals are output from all output terminals by simply increasing the corresponding input channel gain. Make input-to-output re-assignment according to scenes of use. * Refer to p. 82, Block Diagram.

(Refer to p. 41, Bus assignment settings.)

This setting can be performed in either of two ways: On the setting screen display or by way of the front-mounted keys.

Step 2. Set the input sensitivity.

When the D-921E or D-921F is installed, perform this setting by displaying the setting screen. (Refer to p. 26, PAD Settings.)

When the D-922E or D-922F is installed, perform this setting using its DIP switch. (Refer to p. 12 – 13.)

Set the sensitivity so that the front-mounted Input channel indicator [SIG] does not light red.

Step 3. Set the input channel gain.

(Refer to p. 25, Input/Output Gain Settings.)

This setting can be performed in any of three ways: On the setting screen display (two methods) or by way of the front-mounted keys.

Note: When using the D-984VC VCA Control Module, perform gain settings as well for the input channel to be remotely controlled.

Step 4. Set the output channel gain.

(Refer to p. 25, Input/Output Gain Settings.)

This setting can be performed in any of three ways: On the setting screen display (two methods) or by way of the front-mounted keys.

Note: When using the D-984VC VCA Control Module, perform gain settings as well for the output channel to be remotely controlled.

Step 5. Set individual functions as required.

(Refer to p. 18, Setting Flowcharts.)

Refer to the setting flowcharts for the appropriate setting method for the function to be used.

When using Stereo Link, Grouping and Crossover functions, first perform the required settings on the Utility setting screen.

17

Note

It is highly recommended that any changed parameters be immediately saved as preset memory on the Preset Memory setting screen. (Refer to p. 57, Preset Memory Save.) This permits the parameters of each function to be saved and protected, even if the power is switched off. All currently saved parameters can be recalled and reproduced when the power is switch on again. (Refer to p. 60, Initial Preset Memory Selection.) Settings need not be saved when temporarily setting or changing parameters.

6.2. Setting Flowcharts

All the functions described hereinafter can also be set at a PC using the dedicated software. Please access our website "http://www.toa-products.com/international/" for its download.

In the following charts, the Screen shift keys [

] are used to move vertically (next screen display) and the

shift keys [

] to move horizontally between the solid line setting screen boxes (

 

) . For movements

 

within the dotted line setting screen boxes (

) and parameter settings for each setting screen, refer to the

corresponding pages.
