DIGITAL POWER AMPLIFIER Safety first! • aution! This professional device needs to be installed by C qualified personnel only. • P lease 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.
REVAMP2250 Instruction manual • S et level controls on amplifiers all the way down during powerup to prevent speaker damage if there are high signal levels at the inputs. • o not connect the inputs / outputs of amplifiers or consoles D 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. • P ower down & disconnect units from mains voltage before making connections.

DIGITAL POWER AMPLIFIER Connections 1 3 4 2 5 6 8 9 7 11 10 12 13 1. C hannel 2 overload led: when this led lights up, you are overloading the input. Lower the input signal immediately to prevent the amplifier from shutting down. 2. C hannel 1 overload led: when this led lights up, you are overloading the input. Lower the input signal immediately to prevent the amplifier from shutting down. 3. C hannel 2 input gain setting. Adjust the input gain to the output level of your source.
REVAMP2250 Instruction manual powered up. Full details of the available settings can be found below. 6. Channel 2 speaker output on 2 pole euroblock connector. 7. Channel 1 speaker output on 2 pole euroblock connector. 8. C hannel 2 speaker output on speakon connector. Pin 1+ = speaker 2 +, pin 1- = speaker 2 -. 9. C hannel 1 and 2 stereo speaker output on speakon connector. Pin 1+ = speaker 1 +, pin 1- = speaker 1 -; Pin 2+ = speaker 2+, pin 2- = speaker 2-.
DIGITAL POWER AMPLIFIER Operation 1 2 3 4 6 1 5 1. Removable rack ears for 19” rack mounting. 2. Power switch: after switching on the power, the power led will light up after approx 1 second. The limit-muted leds will light up for a few seconds to avoid excessive power on pop noise. 3. Power led 4. C hannel 1 status led bar and mute switch: when the mute switch is pressed, the orange “LIMIT – MUTED” led will light up.
REVAMP2250 Instruction manual switch is pressed, the orange “LIMIT – MUTED” led will light up. This led will also light up when the internal limiter is activated to avoid the amplifier from being overloaded by high input signals. The “CLIP – OVERLOAD” led indicates that the power amplifier is clipping: reduce the input signal at once whenever this occurs !!! The green “SIGNAL - -40dB” led will light up when an input signal is present.
DIGITAL POWER AMPLIFIER of your amplifier to drive a transformer to drive 100V speaker systems. This mode applies a highpass filter to channel 2. Filter characteristics: 12 dB/oct at 50 Hz. Butterworth characteristic. This setting increases amplifier stability when using a 100 volt transformer on output 1. • H1 BRIDGED CH2: both amps are used in bridge. Audio signal C from input 1 is used.
REVAMP2250 Instruction manual !!! IMPORTANT !!! This amplifier relies on convectional cooling only. In normal situations, overheating will not occur due to the class D amplifier topology. Since there are no cooling fans in the amplifier, make sure the convectional cooling system can work properly. The unit can be built in a 19 inch rack system, but it is forbidden to block the ventilation holes provided.
DIGITAL POWER AMPLIFIER 110 VAC operation: it is possible to operate the unit at 110 (115) VAC. Therefore, open the unit and set a wire jumper on the connector for 110 VAC operation.
