ETI Sound Systems, INC LHEC20, LHER20, LHEC30 instruction

RCA output connectors to your recording device. You can record the dry output signal (without DSP effects mixed in) or the full output mix including effects by switching EFFECTS to RECORD in the DSP section on the front panel.

6.SUBWOOFER OUTPUT: Connect either balanced or unbalanced input of your optional powered subwoofer to this XLR connector for increased bass output. The 10” speakers included with your Matrix-600 system can already produce clean bass. In some applications adding an external subwoofer will result in additional bass extension and higher bass SPL. Note that the SUBWOOFER output will only have a signal only when the SUBWOOFER switch is set to the on position.

7.SUBWOOFER ON/OFF SWITCH: Activate the subwoofer output by turning on the SUBWOOFER switch. Filtered low frequencies combined from both the left and right channels will be directed to the SUBWOOFER XLR output and will be cut off from the main speakers. This increases the main speakers’ headroom and allows you to play the entire Matrix- 600 system with higher SPLs. Do not forget to set the SUBWOOFER switch to the off position after you disconnect subwoofer, otherwise your main speaker outputs will remain filtered with a high pass filter, therefore producing limited bass response.

8.FOOTSWITCH: You can connect an optional footswitch which as one or two switches to MUTE the entire Matrix-600 system or to MUTE EFFECTS only. Most industry standard foot switches should work with your Matrix-600 system.

9.HEADPHONES OUTPUT: The Matrix-600 has a dedicated high quality amplifier to power your headphones. You can use the headphones for rehearsals, for monitoring while DJing or during live performances. Connect your headphones to this 1/4” TRS stereo Jack. Control the signal level via the controls on the mixer and the controls

in the HEADPHONES section next to connector.

10.HEADPHONES LEVEL: Use to adjust the overall volume of your headphones. With the MASTER VOLUME (or MONITOR VOLUME) set to normal listening level, the HEADPHONES level control will allow you to set the maximum level of the head- phones. You can easily change the volume of your headphones using the MASTER (or MONITOR) VOLUME controls on the front panel without overdriving your headphones.

11.HEADPHONES MONITOR/MAIN SWITCH: This switch routes your headphones to either the main outputs, controlled the same way as your loud- speakers by the MASTER VOLUME, or the MONITOR output. In this case your headphones perform as mono headphones and are controlled the same way as your MONITOR output by the MONITOR VOLUME and MONITOR LEVELS on the individual channels.

12.POWER SWITCH: Press this switch to turn the MATRIX-600 on or off. The switch is illuminated red in the on position.

13.VOLTAGE SELECTOR SWITCH: DO NOT CHANGE THIS SETTING WITH THE AC MAINS POWER ATTACHED! This switch should only used when the Matrix-600 is transported to a location with a different available AC mains source. Please check that this switch is in the appropriate position for your local electrical source. You will need to change the primary fuse when in accordance with the fuse ratings indicated on the rear panel.

WARNING: Using an improper setting on this switch can destroy the MATRIX-600, create an electrical hazard and void your warranty! The switch setting should match the AC mains power available.

14.AC INLET: Male IEC AC mains connector for standard detachable AC mains cords. This cord will also need to change if the unit is moved between regions with different AC mains voltages. It will require an AC mains switch setting change as well.

15.FUSE HOLDER: The rating of this fuse depends on the local AC Mains voltage. For 115V setting, this fuse is a 8A (T8AL). For the 230V setting, it is a 4A (T4AL) as shown on a rear panel next to the fuse holder.

NEVER REPLACE THE FUSE WITH FUSES OTHER THAN INDICATED IN THIS MANUAL AND ON THE REAR PANEL OF YOUR MATRIX-600 UNIT. NOTE THAT A BLOWN FUSE MAY REPRESENT A SERIOUS MALFUNCTION AND MAY REQUIRE REPAIR. IF THE FUSE BLOWS WHEN REPLACED, REFER YOUR MATRIX-600 TO QUALIFIED SERVICE PERSONNEL AS INSTRUCTED BY B-52 PROFESSIONAL.
