ENGLISH VERSION

DSP-4800 W is an all-in-one wireless digital processor

with 4 inputs and 8 outputs. The unit uses a high preci-

sion 32 bit oating point and 96Khz sampling rate that

greatly reduces distortion. You can control the processor

via Wi-Fi, USB or LAN with the possibility of linking up

to 250 devices. DSP-4800 W shipswithXLR input and

output connectors.

RISK OF ELECTRIC SHOCK

DO NOT OPEN

CAUTION

- WARNING -

When using electric products, basic precautions should

always be followed, including the following:

1. Read all the instructions before using the product.

bathtub,washbowl,kitchensink,inawetbasement,

near a swimming pool, etc.).

3. This product should be used only with a cart or stand

that will keep it level and stable and prevent wobbling.

4. This product, in combination with headphones or

speakers,maybecapableofproducingsoundlevels

thatcouldcausepermanenthearingloss.Donotop-

erateforalongperiodof timeatahighvolumelevel

oratalevelthatisuncomfortable.Ifyouexperience

any hearing loss or ringing in the ears, you should

consult an audiologist.

5. The product should be located so that its location

or position does not interfere with its proper ventilation.

6. The product should be located away from heat

sourcessuchasradiators,heatvents,orotherdevic-

es (including ampliers) that produce heat.

7. The product should be connected to a power sup-

ply only of the type described in the operating in-

structionsorasmarkedontheproduct.Replacethe

fuse only with one of the specied type and size and

with the correct rating.

8. The power-supply cord should:

1. Be undamaged

2. Never share an outlet or extension cord with

other devices so that the outlet’s or extension

cord’s power rating is exceeded, or,

3. Be left plugged into the outlet when left un

used for a long period of time.

9. Care should be taken so that objects do not fall

into and liquids are not spilled thorugh the enclo-

sure’s openings.

10. The product should be serviced by qualied ser-

vice personnel when:

1. The power supply cord or plug has been damaged;

2. Objects have fallen, or liquid has been spilled

onto the product;

3. The product has been exposed to rain; or,

4. The product does not appear to operate nor-

mally or exhibits a marked change in performance;

5. The product has been dropped, or the enclo-

sured damaged.

11. Do not attempt to service the product beyond that

described in the user-maintenance instructions. All

other servicing should be referred to qualied ser

vice personnel.

IMPORTANTSAFETYINSTRUCTIONS:

This product may be equipped tih a polarized line plug

(one blade wider than the other). This is a safety feature.

If you are unable to insert the plug into the outlet, con-

tact an electrician to replace your obsolete outlet. Do not

defeat the safety purpose of the plug.

(ForuseintheU.S.A.)

IMPORTANT:The wires in the mians lead are colored in

accordance with the following code.

BLUE:Neutral

BROWN:Live

As the colors of the wired in the mains lead of this ap-

paratus may not correspond with the colored markings

identifying the terminals in your plug proceed as follows:

The wire which is colored BLUE must be connected to

the terminal which is marked with the letter N or colored

BLACK. The wire which is colores BROWN must be con-

nected to the terminal which is marked with the letter L

or colored RED. Under no circumstances must either of

the baove wires be connected to the ground terminal of

a three pin plug. (ForuseinEurope)

 Features:

• Use 32 bits oating point unit, made the opera-

tion precision more higher.

• Use96KHz sampling frequency, one time higher

than the similar products in the market. Sound

more nicety, less distortion.

• PC long-distance control by use the attached

software: Short distance can be control by con-

necting WIFI, USB connecter or RJ45(LAN) con-

necter. Long-distance control through RJ45(LAN)

connecter. It can control maximium 250 pcs

products, maximnum distance 1000 meters. (It

depends on the electromagnetic environment.)
