Guided Tour - Model LH500 and LH1000 Front Panel

9. LIMITER LED – The indicator light will illuminate when the LIMITER switch is engaged.

10 BALANCE control knob (LH1000 only) – This control knob adjusts the level difference between the Channel

1 and Channel 2 amplifiers. If you are using two different cabinets (for example a 115 and 410), you may want

to drive one a little harder than the other to balance your sound. In the center (12:00 o’clock) position, both

amplifier channels are at equal power. The BALANCE control has no effect when the LH1000 is running in bridge

mode.

11. DIRECT OUT - Use this electronically balanced XLR jack to route signal from the Model LH500 and LH1000 to a

professional mixing console or as a tap to a main PA system via a mic input on the console. The signal output from

this jack is low impedance (100 ohm) with an output level of approximately -30 to -20 dB. You can also use the Direct

Out jack to route signal to an external amplifier with a -10 dB input sensitivity.

12. Fan Filter – Removable sponge filter covering the amplifier’s cooling tunnel vent. The Fan Filter can easy be

removed and cleaned.

13. BRITE switch – Use this switch to turn on the LH Series’ BRITE circuit, which when engaged, adds a pre-set eq

curve to enhance the bass instrument’s high-end response.

14. Limiter switch - This switch is used to engage the LH Series Limiter circuit. The LH Series Limiter is an automatic

dynamics processors used to control the level from reaching clipping. Use the Limiter to even out the loud

transients that can cause distortion. Using the Limiter will also help protect your speaker system

15. Power switch - Use this to power the Model LH500 and LH1000 on or off. The internal power LED lights

whenever the Model LH500 and LH1000 is powered on.
