1.0dB (INPUT): The signal output from an instrument (active or passive) or a line level signal may be connected here by means of a shielded instrument cable.

2.PAD: This switch, when depressed, attenuates the input signal by 15dB. Attenuation allows the Gain control (#4) to be used in a more usable (higher) position. If clipping is indicated with the Gain control way down, attenuation is needed.

3.PEAK LED: This LED flashes when the signal level into the preamp (excluding the graphic EQ) approaches clipping. Adjust the Gain control (#4) until a strong signal from your instrument causes this LED to flicker.

NOTE: If the LED flashes frequently with the gain at a low setting, use the Pad (#2) to attenuate the input signal and readjust the Gain.

4.GAIN: This serves as the input level control for the amplifier. For the best signal- to-noise set this control so the Peak LED (#3) flashes when you strike a string fairly hard.

5.BASS: This is the primary low frequency control. It allows for a range of 8dB of cut or boost at 50Hz.

6.ULTRA-MID:The primary midrange control. Rotate the control to the left of cen- ter for a “contoured” sound (more distant, less midrange output) or to the right of cen- ter for a sound which really cuts through.

7.TREBLE: This is the primary high fre- quency control. It allows for a range of 12dB boost or 19dB of cut at 5kHz.

8.MASTER: Set the overall output level of the amplifier with this control. The Effects Loop and Balanced Out (#20-24) are not affected by the Master control.

9.LIMIT: The SVT-350H uses an internal Optocoupler Limiter to assist in keeping the power amplifier’s output “clean” at extreme volume levels. (All amplifiers may begin to clip their output signals as they approach maximum output levels, resulting in poten- tially damaging distortion.) To engage the Limiter, depress the Limit switch. The adja- cent LED will illuminate whenever the lim- iter circuit is activated. This indicates that the amplifier is nearing full output and the limiter is keeping peak signals from clipping the output.

NOTE: Playing at full power with the Limiter off will give you increased output power, but the sound may be distorted. Use discretion when playing without the Limiter.

10.EQ ON SWITCH: Depress this switch to activate the Graphic EQ. The adjacent LED will illuminate when the EQ is on.

11.GRAPHIC EQ: These sliders control the output of the frequencies indicated below each control. The center position of each control is flat (no boost or cut).

12.POWER ON LED: This LED indicator illuminates when the POWER switch (#15) is ON.

13.POWER SWITCH: This heavy-duty rocker switch applies the power to the amplifier. The amp is ON when the top of the switch is depressed, OFF when the bottom of the switch is depressed.

SVT-350H specifications

The Ampeg SVT-350H is a powerful bass amplifier head that has garnered respect among musicians for its remarkable tonal quality and robust build. Designed for professional performance, the SVT-350H brings together innovative technology with classic Ampeg features, making it a versatile choice for a wide range of musical styles.

One of the standout features of the SVT-350H is its 350-watt output, which allows it to deliver substantial power suitable for both practice settings and large performances. This amp can efficiently drive a variety of speaker cabinets, providing a rich and dynamic sound that can fill any venue. The amplifier is designed with a solid-state preamp combined with a MOSFET power section, which produces a warm and punchy tone reminiscent of vintage tube amplifiers, but with enhanced reliability and reduced maintenance.

A key component of the SVT-350H is its four-band EQ, which allows players to fine-tune their sound with precision. This includes controls for bass, midrange, and treble frequencies, enabling users to shape their tone to suit their playing style or the needs of specific musical genres. Additionally, a midrange frequency switch offers further customization, allowing players to choose between different mid options for greater versatility.

The SVT-350H features a built-in compressor that can be engaged to smooth out dynamics and add sustain to notes, making it an ideal tool for both slap bass and fingerstyle playing. This enhances the amplifier’s capability to handle aggressive playing styles while maintaining clarity and definition.

Connectivity is another strong point of the SVT-350H. It includes an aux input for connecting external audio sources, perfect for practicing along with tracks. It also features a balanced XLR output for direct recording or sending a signal to a PA system, ensuring a seamless integration into any setup.

The durable chassis and reliable components make the Ampeg SVT-350H an industry favorite, well-suited for both touring musicians and local gigging artists. With its powerful output, extensive tonal shaping options, and robust build quality, the SVT-350H continues to be a prominent choice for bass players seeking a reliable and versatile amplifier. Whether for studio work or live performances, this amplifier is designed to deliver exceptional performance and adaptability, making it a cornerstone in the world of bass amplification.
