Important safety instructions CAUTION: High voltage! Risk of death! To avoid lethal electric shock, do not open the casing. There are no user-serviceable components inside. Refer all maintenance to qualified service personnel. Remove the mains cable when the unit is not in use. 10) Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. 11) Only use attachments/accessories specified by the manufacturer.

Online registration Please do remember to register your new BUGERA equipment right after your purchase by visiting www.bugera-amps.com and kindly read the terms and conditions of our warranty carefully. Should your BUGERA product malfunction, our goal is to have it repaired as quickly as possible. To arrange for warranty service, please contact the retailer from whom the equipment was purchased.
you can turn the relevant tone control toward 0 (maximum cut). $ By cutting certain frequencies instead of boosting others, you protect your equipment from extreme volume peaks (“clipping”) and get valuable headroom. (12) The FREQUENCY selector adjusts the frequency of the MID rotary knob (see (11)). There are five settings available: 220 Hz, 450 Hz, 800 Hz, 1.6 kHz and 3 kHz. (13) The BRIGHT switch boosts the frequency range centered at 2 kHz by 6 dB.
= When using a mono effects processor, route the effect signal only to RETURN CHANNEL A. (29) SEND jack: To send an audio signal from the BTX to an effects processor, use this ¼" TS jack. INSERT CHANNEL section channel A (and not of channel B) are used. Mono-bridged mode is active when the button (21) glows. Examples: = Driving a single 8-Ohm loudspeaker. = Driving a single 4-Ohm loudspeaker.
always a separate input signal as well as a separate output signal. 2-channel mode is active when the button (21) is not lit (off). Effects Processor Examples: = 2-channel (stereo) playback = Two independent mono signals, such as instrument signal and monitor mix = Bi-amp operation, whereby bass frequencies are run on channel A, and high frequencies on channel B (see 4.2 “Bi-amping”).
—where Z1, Z2 etc. are each the impedance of a single speaker and Ztotal is the resulting impedance of all speakers. For two speakers (Z1 and Z2), the formula reads as: Z total = Z1 ⋅ Z 2 Z1 + Z 2 Via the formula, you get a 4 Ω load with: = one 4-Ohm speaker = two 8-Ohm speakers = one 8-Ohm speaker and two 16-Ohm speakers $ As the speaker impedance decreases, the output power of the BTX increases. High output power can damage your speakers.
$ Should you register distractive signals such as noise or hissing, we recommend separating the amp input from the signal source. This way, you can quickly determine if the noise originates from the equipment connected to the amp. Make sure to turn the volume to a minimum before turning it on (MASTER rotary knob turned fully left) to avoid any damage that may occur to your loudspeakers. Footswitch connector The footswitch connector is a ¼" TRS connector.
