Stand by

There are two different levels of voltage controlling the tubes:

1)the basic voltage intended to warm the tube to minimum operational temperature. This voltage is always applied to the tube whenever the power switch is in the on position.

2)the operating voltage (plate voltage) which drives the tube. The operating voltage is turned off with the STANDBY switch.

The green LED indicates the unit is in standby mode, the red LED above the STANDBY switch indicates normal playing mode.

If you are using only one channel of the switch the other channel into standby mode.

Volume

VOLUME controls how much the input signal is amplified, thereby controlling the output volume of the channel. Due to the special LINE DRIVER circuitry in each channel’s input, VOLUME offers a very wide range of control which also accommodates devices with very low output levels (300 mV are perfectly adequate to drive the output stage; voltages up to 10 volts can be accepted without overloading the input).

Presence

With tube amplification, the higher frequencies (PRESENCE) are most effectively controlled at the power amp stage. This frequency range plays a major role in determining the character of the guitar sound and its ability to cut through.

The intensity of the PRESENCE control depends to a great degree on the guitar sound itself: a heavily overdriven sound with a great deal of overtone energy will respond to the PRESENCE control much more dramatically than will a clean sound with little overtone content.

Over the last 30 years of tube amp tradition, two different types of PRESENCE control have established themselves as standard:

) the " British” type, which only affects higher frequencies, and only boosts, and

) the “American” type, which affects a broader range of frequencies from high mids to harmonic overtones, and can either boost or cut.

Since both PRESENCE philosophies make sense, and both allow for very different characters, particularly with overdriven sounds, the VS 250 offers both types.

PRESENCE 1 is the “American” type. The signal is unaffected when the control is in the " 3-o'clock"position.

PRESENCE 2 is the " British” type. in the fully counterclockwise position, the sound is unaffected.

VS 250 specifications

The Hughes & Kettner VS 250 is a versatile and powerful guitar amplifier head that has garnered attention for its remarkable performance and array of features. Designed to accommodate various musical styles and preferences, the VS 250 is particularly popular among guitarists who value both tone and flexibility in their sound.

At the heart of the VS 250 is its innovative tube technology. The amplifier features a unique combination of tube-driven circuitry and modern digital components, allowing it to deliver the warmth and character characteristic of traditional tube amplifiers while benefiting from the precision and functionality of modern technology. This blend ensures that guitarists experience rich harmonic overtones and dynamic response, producing a sound that is both responsive and expressive.

One of the main features of the Hughes & Kettner VS 250 is its impressive tonal flexibility. The amp includes multiple channels, each with its own distinct voice. Guitarists can easily switch between clean, crunch, and lead tones, allowing for seamless transitions during performances or studio sessions. The well-designed EQ section offers extensive control over bass, middle, and treble frequencies, enabling players to sculpt their preferred sound profile.

Additionally, the VS 250 incorporates built-in digital effects, including reverb and delay. These effects allow users to enhance their tone without the need for external pedals, streamlining the setup process. The intuitive user interface makes it easy for players to customize settings, ensuring they can dial in their desired sound quickly.

The amp also features a series of outputs, allowing for easy integration with various speaker cabinets. This adaptability makes the VS 250 suitable for different performance environments, from small gigs to larger venues. Furthermore, it's equipped with features for direct output, making it ideal for recording situations.

Durability is another hallmark of the Hughes & Kettner VS 250. Built with high-quality components and a rugged chassis, this amplifier is designed to withstand the rigors of life on the road. Its compact size also makes it a convenient choice for traveling musicians.

In summary, the Hughes & Kettner VS 250 combines modern technology with traditional tube warmth to create an amplifier that is both powerful and versatile. Its range of features, tonal flexibility, and built-in effects make it a compelling choice for guitarists looking to elevate their sound. Whether on stage or in the studio, the VS 250 stands out as a reliable partner for musical expression.
