1. INTRODUCTION
Thank you for purchasing one of our MISTRAL stereo power amplifier.
The MISTRIAL 2500/4000/6000 are the line of high power, low profile, professional power amplifiers with advanced features and great reliability. An automatic speed fan matches cooling capacity with heat requirements. The amplifiers contains two independent channels, with separate AC transformer secondaries, power supplies and protections system. Each channel has independent protective circuitry against open circuit, short circuit, mismatched loads and over temperature and LED indicators for operating/protection, limit, power on and clip. The power outputs employ standard power connectors and all the inputs are electronically balanced.
Enjoy your MISTRAL stereo power amplifier and make sure to read this Manual carefully before operation.
2. FEATURES
Mountable in a 19" rack unit, stereo high power amplifier Fantastic audio quality even with extremely high volume levels Solid and durable can be mounted into a cabinet User-controllable clip limiter 2 700 watt EIAJ on 4 ohms for MISTRAL 2500 2 1000 watt EIAJ on 4 ohms for MISTRAL 4000 2 1400 watt EIAJ on 4 ohms for MISTRAL 6000 Stereo (dual-channel) or bridge mono operating modes Balanced XLR inputs/parallel outputs to ensure noiseless long wiring Binding post and Neutrik Speakon connectors for output Single channel, bridge and bi-amp output wiring possibility Front panel LED indicators for operating/protection, limit, power on and clip Accurate gain control Independent DC and thermal overload protection on each channel automatically protects amplifier and speakers Over-heat protection for each channel Manufactured under QS9000, VDA6.1 certified management system

CLIP LED
When the signal distortion reaches or surpasses 0.5% , the LED lights up. This means the output level of signal source is too high and it is time to reduce the input level until the LED turns off.
3
OUTPUT LIMITER LED
When the unit limits the output signal, the LED lights up.

OPERATION AND PROTECTION LED
In normal operation, the LED is green; If the LED is red, it means the unit is in heat protection, no signal output at the time and over-heat inside the unit (the surface temperature of power transistor is 110 ), the temperature must be lowered through better ventilation and decrease the signal level etc. After the temperature dropped, the protection stop and meanwhile the LED turns off with the unit recover normal work.

a. IEC SOCKET FOR AC POWER CABLE (For MISTRAL 2500/4000)
Connect the supplied main cord. Do not insert the power cord into the MISTRAL stereo power amplifier and into the AC Outlet until voltage has been correctly set.
b. POWER CORD (Only for MISTRAL 6000)
This is an IEC power cord. You can connect the plug of power cord to the mains. Please make sure the voltage accepted by the unit.

Set the switch at "ON" position, once the output level is above maximum, the clip begins, thus keeping consistent output level for protecting apparatus. If the switch is set at "OFF" position, this clip function doesn't work.
BALANCED INPUT CONNECTOR
12
These connectors connect the input signal of CH 1 and CH 2 separately.
BALANCED OUTPUT CONNECTOR
13
These two output connectors are parallelled inside with input connectors. It enables the unit work under parallelled mode. Please also refer to wiring diagram for paralleled mode.
MODE SELECTOR
14
The MISTRAL stereo power amplifiers present two operating modes:
- Stereo Mode
In this mode, CH 1 and CH 2 operate independently (as a normal stereo amplifier). The CH 1 input signal will be output from the CH 1 output connector, and CH 2 input signal will be output from the CH 2 output connector.
- Bridge Mode
In this mode, CH 1 input signal will be output from the bridge-mono output connector. On the other hand, the output level control of CH 2 should be turn to the minimum.
4
4. APPLICATION
The MISTRAL stereo power amplifiers provide two operating modes: stereo mode and bridge mode, you can decide each specific operating mode according to your actual application circumstance. Please see following diagram for connecting the power amplifier into your audio system.
- Stereo Mode
In this mode, CH 1 and CH 2 operate independently (as a conventional stereo amplifier). The CH 1 input signal will be output from the CH 1 output connectors, and the CH 2 input signal will be output from the CH 2 output connectors.
