Montarbo LION 2-1500 Lion Series Switching Power Professional Amplifier

Introduction

The LION 2-1500 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 2-1500 switching power professional Amplifier will provide a perfect performance, what you get is unprecedented performance at an incredibly attractive price.

Control Element

FRONT PANEL

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. 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.

REAR PANEL

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) 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: NC – Not used
   Mode 4: CHA/CHB sub-Stereo
   CHA and CHB are stereo,output signal is low frequency, X-over FREQ CHA/CHB is available.

Control Element

Mode 5: NC – Not used
Mode 6: 70V-Stereo
CHA and CHB are stereo 70V line output, the min load is 4Ω. Mode 7: NC – Not used
Mode 8: NC – Not used
Mode 9: Auto-standby
If the switch is to on, and no signal input or signal input peak less than -20dB after 20 minutes is detected, LION 2-1500 will go to standby (ERP Standards). If a signal input peak greater than -20dB is detected, LION 2-1500 can restart.

CHA SPEAKON NL-4R
Connect the amplifier to you speaker with these speaker jacks.

CHB SPEAKON NL-4R
Connect the amplifier to you speaker with these speaker jacks.

AC Input
Use it to connect your Amplifier to the supplied AC cord.

Applications

Stereo Operation
The LION 2-1500 Amplifier can be used in the stereo mode as two separate 1500 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.
