Atenuador de potência Bugera PS1 000-BV100-00010 atenuador inline passivo de 100W

The Bugera PS1 100W passive inline power attenuator reduces amplifier output level while preserving tonal character. Designed for electric guitar amplifiers and other audio power amps, this passive device places between the amplifier output and the speaker load to lower volume without active electronics. It enables controlled power-tube saturation at reduced listening levels and provides a degree of speaker protection by dissipating excess power as heat. The compact, inline design is suitable for stage, rehearsal, and studio environments where maintaining amp feel and response at lower volumes is required.

Advantages

The attenuator operates passively, requiring no external power or batteries and introducing minimal circuitry between amp and speaker. It supports up to 100 watts of amplifier output and is built to handle the thermal and electrical demands of reduced-volume operation. Because it is inline and simple to connect, it preserves the natural dynamics and harmonic content of tube amplifiers while enabling practical volume control. The unit also helps protect speakers from excessive power when driving high output levels.

Suitable for

• Electric guitarists who want power tube break-up at lower stage or home volumes
• Studio engineers seeking controlled amp saturation during recording
• Rehearsal rooms and practice sessions where reduced volume is necessary
• Live sound situations requiring volume reduction without changing amp tone

Key specifications

• Type: Passive inline power attenuator
• Power handling: 100 W continuous rating
• Application: Guitar amplifiers and similar audio power amplifiers
• Function: Reduces output level while preserving amp dynamics and tone
• Connections: Inline between amplifier output and speaker (speaker-level wiring)

How to use

Install the attenuator by connecting the amplifier speaker output to the attenuator input and then connecting the attenuator output to the speaker cabinet. Ensure impedance compatibility between amplifier, attenuator, and speaker to avoid mismatches. Start with the attenuator set to a mild reduction and gradually increase attenuation until the desired balance between volume and power-tube saturation is achieved. Monitor amplifier temperature during extended use since the device dissipates excess power as heat.

Recommendations

Use the attenuator with proper ventilation and avoid enclosing it in tight, unventilated spaces during prolonged high-power use. Verify impedance settings and speaker wiring before powering the amplifier. For critical recording or performance situations, test settings in advance to determine the preferred attenuation level for tone and volume.
