• DO NOT USE THIS APPARATUS NEAR SPLASHING, FALLING, SPRAYING, OR STANDING LIQUIDS. • CLEAN ONLY WITH LINT-FREE DAMP CLOTH AND DO NOT USE CLEANING AGENTS. • ONLY CONNECT POWER CORD TO A POLARIZED, SAFETY GROUNDED OUTLET WIRED TO CURRENT ELECTRICAL CODES AND COMPATIBLE WITH VOLTAGE, POWER, AND FREQUENCY REQUIREMENTS STATED ON THE REAR PANEL OF THE APPARATUS. • PROTECT THE POWER CORD FROM DAMAGE DUE TO BEING WALKED ON, PINCHED, OR STRAINED. • UNPLUG THE APPARATUS DURING LIGHTNING STORMS OR WHEN UN

(Whenever playing at full output levels, it is recommended that you use the Speakon® jacks.) 14. STEREO/DUAL MONO / MONO BRIDGE: Use this switch to set the operating mode of the amplifier. When the switch is out, the amplifier is in the Stereo or Dual Mono Mode; when the switch is depressed the amplifier is in the Mono Bridge Mode. In the Stereo mode, use the Power Amp A input (#18) and the Sensitivity Channel A control (#1) for the LEFT channel, and the Power Amp B input (#15) and the Sensitivi

5. ULTRA HIGH: Use this switch to boost the high frequencies. The adjacent LED illuminates when the Ultra High is active. 6. ULTRA LOW: Use this switch to boost the low frequencies. The adjacent LED illuminates when the Ultra Low is active. 7. BASS: Use this control to adjust the low frequency output of the amplifier. 8. ULTRA MID: Use this control to adjust the midrange frequency output of the amplifier. 9. TREBLE: Use this control to adjust the high frequency output of the amplifier. 10. FX BL

5. BASS: This is the primary low frequency control which allows for 8dB of cut or boost at 50Hz. 6. ULTRA-MID: This is the primary midrange control. Rotate the control to the left of center for a “contoured” sound (more distant, less midrange output) or to the right of center for a pronounced (more upfront) tone. 7. TREBLE: This is the primary high frequency control which allows for 12dB of boost or 19dB of cut at 5kHz. 8. MASTER: Set the overall output level of the amplifier with this control.

9. LIMITER: The B2/B2R uses an internal Optocoupler Limiter to assist in keeping the power amplifier’s output “clean” at extreme volume levels. (All amplifiers begin to clip their output signals as they approach maximum output levels, resulting in distortion which may damage your speakers.) To engage the Limiter, depress the Limit switch. Whenever the amplifier is at full power, the adjacent LED will flash. This is an indication that the limiter is keeping peak signals from clipping the output.

Do not attempt to defeat the safety ground connection! 15. SPEAKERS: Use these jacks to connect the amplifier to your speaker(s) using high quality speaker cables terminated with 1/4” connectors. WARNING: The speaker output of this unit can exceed 10 Watts and could be a shock injury. Connection to speakers should be performed by a skilled person in compliance with local building codes. Class 2 wiring is required for speaker cables. Use of external speakers outside the ratings stated at the spea
