Professional class TD amplier – 4 x 1200W @ 2 ohms

ICE 4800 is a professional amplier that features

TD class amplication, which combines the e-

ciency of a digital power supply with the sound

clarity of a high-quality analog amplication circuit.

Thanks to its design, the amplier allows the peak

power to follow the dynamics of the music pro-

gram, being able to reproduce – at its peak - up to

twice the RMS power without clipping. In terms of

performance, ICE 4800 delivers an RMS power of

4 x 600W @ 8 ohms, 4 x 900W @ 4 ohms and 4 x

1200W @ 2 ohms, sports a wide range of protec-

tions and is very ecient with respect to power

consumption.

Specications

Output

• Output power (8 ohms): 4 x 600W

• Output power (4 ohms): 4 x 900W

• Output power (2 ohms): 4 x 1200W

• YSProcessing: The amplier adds low-frequen-

cy compensation to

• enhance speaker output.

mal, RF protection, On/o muting, DC fault

shutdown & active inrush limiting.

2. SAFETY

Important Safety Instructions

1. Read these instructions.

2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this apparatus near water.

6. Clean only with dry cloth.

7. Do not block any ventilation openings. In-

stall in accordance with the manufacturer’

instructions.

8. Do not install near any heat sources such as

radiators, heat registers, stoves, or other appa-

ratus (including ampliers) that produce heat.

9. Do not defeat the safety purpose of the polar-

ized or grounding-type plug. A polarized plug

has two blades with one wider than the other.

A grounding type plug has two blades and a

third grounding prong. The wide blade or the

third prong are provided for your safety. If the

provided plug does not t into your outlet,

consult an electrician for replacement of the

obsolete outlet.

10. Protect the power cord from being walked on

or pinched particularly at plugs, convenience

receptacles, and the point where they exit

from the apparatus.

11. Only use attachments/accessories specied

by the manufacturer.

12. Use only with the cart, stand, tripod, brack-

et, or table specied by the manufacturer,

or sold with the apparatus. When a cart is

used, use cau- tion when moving the cart/

apparatus combination to avoid injury from

tip-over.

13. Unplug this apparatus during lightning storms

or when unused for long periods of time.

14. Refer all servicing to qualied service per-

sonnel. Servicing is required when the appa-

ratus has been damaged in any way, such as

power supply cord or plug is damaged, liquid

has been spilled or objects have fallen into

the apparatus, the apparatus has been ex-

posed to rain or mois- ture, does not operate

normally, or has been dropped.

RISK OF ELECTRIC SHOCK

DO NOT OPEN.

CAUTION!

To reduce the risk of electric shock and

re, do not expose this equipment to

moisture or rain.

WARNING!

CAUTION: TO REDUCE THE RISK OF ELECTRIC

SHOCK, DO NOT REMOVE COVER (OR BACK).

NO USER-SERVICEABLE PARTS INSIDE. REFER

SERVICING TO QUALIFIED SERVICE PERSONNEL.

Explanation of Graphical Symbols

The lightning ash with arrowhead

symbol within an equilateral triangle

is intended to alert the user to the

presence of uninsulated "angerous

voltage" within the product' s enclosure

that may be of sucient magnitude to constitute a

risk of electric shock to persons.

The exclamation point within an

equilateral triangle is intended to alert

the user to the presence of important

operating and maintenance instructions

in the literature accompanying the product.

3. CONTROLS AND FUNCTIONS

Front panel

1. POWER switch and indicator Press to tog-

gle the power on or o. The POWER indicator

lights up green when the power is ON.

2. Power source indicator POWER indicator

light up when unit is turn on ,the power ampli-

er is connect with power and will be running

works within 3-5 seconds.

3. Volume control knobs Each control knob ad-

justs the volume of the corresponding channel

from -00 dB to 0 dB.

4. SIGNAL indicator Lights up green when the

corresponding channel's output level exceeds

5 Vrms (equivalent to 3 W into an 8Ω load, or 6

W into a 4Ω load)

5. CLIP indicator Lights up red when the output

signal distortion on the corresponding chan-

nel rises above 1% indicating that "Clipping"

has occurred because the signal level is too

high.

6. Protect indicator Lights up red to indicate

that protection is in eect. Specically, lights

up if the heat sink overheats, or if a DC voltage

is detected at the amplier outputs. Also lights

up for about 5 seconds at time of power-on,

as the amp gets ready to operate. To pro-

vide protection, the unit will not output any

sound from the speakers while this indicator

is lit up. When start-up is completed or the

problem is corrected, the indicator goes o

and normal operation resumes.

7. BRIDGE indicator Lights up the yellow when

the button turn to BRIDGE at MODE on rear

panel.

8. PARALLEL indicator Lights up the yellow

when the button turn to PARALLEL at MODE

on rear panel

9. The amplier uses forced-air cooling. The

cooling fans draw air in from the front and

exhaust it through the rear. Please be sure

that you do not block the air intakes or ex-

haust vents.

10. Install the security cover When install

19'inch (1RU) rack mounting, please use the

#10 or 6mm screws from amplier

Rear panel

1. Channel 1 XLR Input This XLR input is a

balanced input. Connect this input to the left

output of your mixer.

2. Channel 1 Link Socket This balanced socket

is used to link another amplier.

3. Channel 2 XLR Input This XLR input is a

balanced input. Connect this input to the left

output of your mixer.

4. Channel 2 Link Socket This balanced socket

is used to link another amplier.

5. Operation Mode Selector This switch is used

to choose the operating mode of the power

amplier: Mode stereo: 2 inputs(channel 1

and 2) and 2 outputs are used. Mode parallel:

1 input (channel 1) and 2 outputs are used.

Mode bridge: 1 input(channel 1) and 1 output

are used.

6. Input Sensitivity Selector This selector

allows to choose the input sensitivity: either

1.0V, 1.4V, 2.0V).

7. ON/OFF Switch If you set this

switch ON, the amplier adds low- frequen-

cy compensation so as to enhance speaker

output. The results (the actual change in the

low-frequency balance) will vary according to

the speaker type.

8. Channel 1/3 Turn Lock Output Connect this

turn lock output to a speaker. The branching is

+1,-1(except in bridge mode where the branch-

ing is +1,+2 ).

9. Channel 2/4 Turn Lock Output Connect this

turn lock output to a speaker. The balance is

+1,-1.

10. AC Cord Plug this cord into the power supply

socket. (Before using the power amplier,

check if the power supply is 220V).

11. Air Entrance This part is the air entrance.

Don't obstruct it.
