PROFESSIONAL DIGITAL AMPLIFIER

Safety First!

• Caution! This professional device needs to be installed by

qualiﬁed personnel only.

• Please check the carton box for any kind of damage on

reception of the goods. In case of a damaged carton, please

contact your dealer before opening the carton.

• !!!! Danger !!!! Exposure to high sound levels may cause a

permanent hearing loss. Individuals vary considerably to sound

pressure level induced hearing loss but nearly everyone will

lose some hearing if exposed to high sound pressure levels for

a sufﬁcient amount of time. Therefore it is recommended that

all persons exposed to equipment capable of producing high

sound pressure levels, such as this ampliﬁer, be protected by

hearing protection while installing or operating this unit.

• Read all documentation before operating your equipment.

• Keep all documentation for future reference.

• Save the carton and packing material even if the equipment has

arrived in good condition.

• Should you ever need to ship the unit, use only the original

factory packing.

• Do not spill water or other liquids into or on the unit.

• Make sure power outlets conform to the power requirements

listed on the back of the unit.

• Do not use the unit if the electrical power cord is frayed or

broken.

• Always operate the unit with the AC ground wire connected to

the electrical system ground.

Instruction manualREVAMP1680

• Set level controls on ampliﬁers all the way down during power-

up to prevent speaker damage if there are high signal levels at

the inputs.

• Do not connect the inputs / outputs of ampliﬁers or consoles

to any other voltage source, such as a battery, mains source, or

power supply, regardless of whether the ampliﬁer or console is

turned on or off.

• Power down & disconnect units from mains voltage before

making connections.

• Do not use the unit near stoves, heat registers, radiators, or

other heat producing devices.

• Do not operate equipment on a surface or in an environment

which may distort the normal ﬂow of air around the unit. If the

unit is used in an extremely dusty or smoky environment, the

unit should be periodically “blown free” of dust.

• Do not remove the cover. Removing the cover will expose you

to potentially dangerous volt ages.

• Do not drive the inputs with a signal level higher than that

required to drive equipment to full output.

• Do not run the output of any ampliﬁer back into another input.

• In case of mal-function this device should be serviced by

qualiﬁed service personnel only.

• This unit has NOT been designed for use in mobile applications,

such as: mobile discobars, mobile PA systems, Live bands, audio

rental systems, …

such as: mobile discobars, mobile PA systems, Live bands, audio

rental systems, …

• Removable rack-ears

This ampliﬁer is equipped with 2 stereo bus inputs with

passthrough. These bus inputs are ideal when you want to hear the

same audio signal in different output zones. For example: zones 1

to 4 use bus 1 input. Zones 5 to 7 use bus 2. Zone 8 is set to line

in and uses its own input signal. In this case, set the input selector

for zone 1 to 4 to bus 1, from zone 5 to 7 to bus 2 and zone 8 to

line in.

The trigger input is ideal when you want to switch on the power

ampliﬁer automatically using an external AC or DC trigger signal

coming from your audio system. The ampliﬁer will be switched on

as long as the trigger voltage is present. Alternatively, you can set

the power on mode switch to the audio trig position: the amp will

automatically switch on when a sufﬁciently strong audio signal

is present at the input. The input sensitivity for the audio trigger

function is 15 mV on all inputs. After a few minutes of silence, the

ampliﬁer will automatically switch itself off.

1. Bus 1 unbalanced stereo input on RCA connector: This input

can be selected in any zone by setting switch “10” to the BUS

1 position.

2. Bus 2 unbalanced stereo input on RCA connector: This input

can be selected in any zone by setting switch “10” to the BUS

2 position.

3. Bus 1 unbalanced stereo pass through on RCA connector: the

audio signal applied to the BUS 1 input can be tapped here.

4. Bus 2 unbalanced stereo pass through on RCA connector: the

audio signal applied to the BUS 2 input can be tapped here.

5. Power on mode selector: power on: the ampliﬁer is powered

on when the power switch at the front panel is switched to

the on position. In the Audio Trig position, the ampliﬁer will be

switched on automatically when a strong audio signal is present

at the input. In the Ext Trigger position, you have to apply a

3-30 V AC or DC voltage at the jack input “6”. The power

switch on the front panel must be in the on position. In the off

position, the ampliﬁer will always be off.

6. Trigger input jack: 3.2 mm monojack input for the 3-30 V AC

or DC trigger voltage. The trigger voltage will switch on the

ampliﬁer when switch “5” is in the Ext Trigger position and the

front panel power switch is in the on position.

7. Ext Trigger output jack pass through (out) connector, 3.2 mm

mono minijack: the trigger voltage applied at connector “6” is

passed through via this connector.

8. Channel input gain setting. Adjust the input gain to the output

level of your source.

9. Ampliﬁer mode selector: set to stereo for normal operation, set

to bridge for bridged mode. Load impedance in bridged mode

must be 8 ohms or higher.

10. Input selector for zone 1. Select Bus 1, Bus 2 or Line in.

11. Zone 1 stereo speaker outputs on euroblock. Minimum load

impedance is 4 ohms in stereo mode and 8 ohms in bridge

mode.

12. Line in: unbalanced stereo input on RCA connector. In bridge

mode: use left input only.

13. Mains inlet connector: connect the mains cable supplied with

14. Mains fuse: when the fuse blows, replace only with the same

type and fuse rating.

15. Mains voltage selector: set to 230 or 115VAC according to your

local mains voltage.

1. Removable rack ears for 19” rack mounting.

2. Power switch.

3. Power led.

4. Zone 1 - 8 status leds: green = active, red = inactive, protect or

overload.
