LION SERIES
Introduction
The LION 2-1000 switching power professional amplifier is designed for professional use on stage. The high-quality components and the carefully designed circuits ensure excellent audio performance and an extremely linear frequency response. In fact, the switching technology offers, together with an increased efficiency and a better control of heat dissipation than conventional power supply systems, a drastic reduction of dimensions and weight, for easier transportation and installation. This Amplifier guarantees total reliability and a trouble-free use even in the most demanding conditions. We believe the LION 2-1000 switching power professional amplifier will provide a perfect performance, what you get is unprecedented performance at an incredibly attractive price.
Features
High current switching power allowing high power output with low noise and low distortion.
Substantial protection circuitry like thermal, short circuit, power on/off muting and therefore protection.
Built-in limiter. Balanced XLR-TRS combo input jack &XLR/Link output. Stereo/Parallel/Bridged/Sub/70V/100V/Mute mode select. Speakon output connectors. Front mounted gain controls for easy access. Signal, Clip protect, and Power LED indicators to monitor performance.

1- Power Switch It switches ON/OFF the unit main power.
2- Power LED The Power LED lights up when the amplifier is powered on.
3- Level Control These volume controls adjust the volume level.
4- Protection LED In normal operation, the LED will not light up; if the LED lights red, it means the unit stay in protection without sound output.
5- Signal LED These green LEDs light up when the respective channel’s output signal pass through.
6- Clip LED The red LED lights up when the input signal is too loud, and when the input signal decreases the LED will turn off.
7- Bridged LED The Bridged LED lights up when the amplifier is in Bridged Mode.
8- Air Intake Vents The Amplifier employ a variable speed internal cooling fan to intake the air through front grill to keep it running cool even under extreme operating conditions. Please keep these vents clear and free from obstruction at all times to insure proper cooling.

1- Channel A Link out
2- Channel A XLR/TRS Input This XLR/TRS jack will accept any balanced or unbalanced low impedance line level source by means of a three-pin XLR/TRS plug. The wiring for the plug is as follows: Pin1(Sleeve)=Ground, Pin2(TIP)=Signal+, Pin3(Ring)=Signal-.
3- Channel B TRS/XLR Input This XLR/TRS jack will accept any balanced or unbalanced low impedance line level source by means of a three-pin XLR/TRS plug. The wiring for the plug is as follows: Pin1(Sleeve)=Ground, Pin2(TIP)=Signal+, Pin3(Ring)=Signal-.
4- Channel B Link out
5- SUB-X-OVER FREQ Cut off frequency selectors for low-pass (SUB) filters, the value can be set from 50Hz to 250Hz. X-OVER FREQ is available in Mode 4(SUB-Stereo) and Mode 5(SUB-Bridged) only.
6- MODE Mode 1: CHA/CHB stereo
Input and output channels are independent. Mode 2: CHA/CHB parallel
Outputs are the same with any channel input. Mode 3: CHA/CHB Brided
Input the signal to Channel A, connect the speaker’s”+” to the output 1+, connect speaker’s ‘-‘ to the output 2+. Mode 4: CHA/CHB sub-Stereo CHA and CHB are stereo,output signal is low frequency, X-over FREQ CHA/CHB is available.

Mode 5: CHA/CHB sub-Bridged CHA/CHB are Bridged,input the signal to CHA, output signal is Bridged, X-OVER FREQ CHA is available.
Mode 6: 70V-Stereo CHA and CHB are stereo 70V line output, the min load is 4.
Mode 7: 100V-Bridged CHA and CHB are Bridged, input the signal to CHA, output signal is 100V Bridged, the min load is 4.
Mode 8: NC Not used
Mode 9: Mute The amplifier will be muted by turning on the switch.

LION SERIES
Applications
Stereo Operation
The LION 2-1000 Amplifier can be used in the stereo mode as two separate 1000 watt units, each capable of driving loads down to 4 ohms. Each channel operates independently and has its own input connectors, sensitivity level controls, signal indicator LEDs, automatic limiter, fault protection circuitry, power amp, and speaker outputs. In the stereo mode, the signal smart switch must be set to the stereo position. One application of the stereo mode uses one channel of the amplifier for the left house speakers and the other channel for the right. The mixing board channels can be panned left or right according to the position of the instruments on the stage. This approach provides a more accurate reproduction of the live performance.

Applications
Mono Bridge Operation
The two internal power amplifiers (CHA and CHB) can be bridged together to form a single, higher powered amp. This is especially useful when using the amplifier to power a subwoofer. In the mono mode, the amplifier uses the Channel A input jacks and sensitivity control (Channel B’s are disabled). When operation in this mode, each channel is independently protected. The signal smart switch must be set to the bridge position and the minimum speaker load impedance must be 4 ohms.
