mode selection

The three-position, recessed Mode Select switch (located on the rear panel) configures the amplifier for Stereo, Parallel or Bridged mode. Amplifiers are factory-configured for Stereo mode. Shut the amp off before changing modes.

stereo

In Stereo mode,both channels operate independently,with their input atten- uators controlling their respective levels. Signal at Channel A’s input produces output at Channel A’s output,while signal at Channel B’s input produces out- put at Channel B’s output. Recommended minimum nominal load impedance for stereo operation is 2 Ohms per channel.

parallel

When set to Parallel mode, program material applied to Channel A’s input will appear at both Channel A and B outputs.The attenuator for Channel A controls the level for both A and B outputs.

bridged

Bridged mode straps both amplifier channels together to make a single- channel monaural amplifier. One channel pushes and the other pulls equally, increasing the power output over that of either channel alone

(see Specifications). Signal is applied to the Channel A input only. Channel A’s attenuator is used to control signal level.

Use extreme caution when operating the amplifier in Bridged mode. Never ground either side of the speaker cable when the amplifier is in Bridged mode; both sides are “hot.”

If an output patch panel is used, all connections must be isolated from each other and from the panel.The recommended minimum nominal load imped- ance in the Bridged mode is 4 ohms, which is the equivalent to driving both channels separately at 2 ohms.

LT Series, ST Series specifications

Peavey Electronics, a pioneer in audio equipment, has made significant strides in the amplifiers market, particularly with its LT and ST series. These series embody Peavey’s commitment to quality sound, rugged design, and innovative technology, making them popular among both novice musicians and seasoned professionals.

The Peavey LT Series is designed primarily for portable use, making it an excellent choice for musicians on-the-go. One of the prominent features of the LT Series is its lightweight construction, allowing for easy transport without compromising sound quality. The series incorporates advanced DSP technology, which provides users with a variety of sound shaping tools. This includes presets for different genres and venues, ensuring that artists can achieve the desired tone quickly and efficiently. Additionally, the LT models often include Bluetooth connectivity, enabling musicians to stream music and use mobile apps for easy control and adjustments.

On the other hand, the Peavey ST Series is tailored more towards permanent installations and professional settings. These models boast higher wattage output, catering to larger venues and more demanding applications. The ST Series amplifiers are renowned for their robust build quality, with heavy-duty enclosures designed to withstand the rigors of live performances. The signature Peavey sound is preserved in these models, thanks to their high-efficiency circuits and premium components. The ST Series is equipped with advanced cooling systems to prevent overheating, ensuring reliable performance even during extended use.

Both series utilize Peavey’s patented technologies, such as the DDT (Dynamic Download Technology) which protects speakers from distortion by dynamically adjusting power levels without sacrificing sound fidelity. This technology not only enhances sound clarity but also extends the life of the connected speakers, making the LT and ST series efficient and long-lasting investments.

Moreover, the user interface on Peavey’s LT and ST models is designed for ease of use, featuring intuitive controls that allow musicians to tweak their sound in real time without getting lost in complex menus. The durability and reliability of these amplifiers make them suitable for a variety of applications, from small venues to large concert halls.

In summary, the Peavey LT and ST series represent exceptional choices for various musical contexts, driven by innovative technology, quality construction, and versatile performance capabilities. Whether needed for portable gigs or fixed installations, these series deliver powerful, clear sound that meets the demands of today’s musicians.
