Master Volume

The Effects Blend functions only when the Effects Loop is being used. It is activated when a 1/4" phone plug is inserted into the Effects Receive jack (see the “Effects Loop” section for more information).

Note: Pulling the Effects Blend control knob outward defeats the internal limiter circuit. To activate the limiter, push the control in.

The Master Volume adjusts the level being sent to the power amplifier in your Bass 350—it con- trols the overall volume of the unit. It does not affect the level of the record XLR output in the “line” position.

Losses in level caused by effects units can be recovered by increasing the Master Volume.

FAN & FAN DEFEAT SWITCH

The power amp is cooled by an extruded aluminum heatsink and a thermostatically controlled fan. This fan turns on when the heatsink reaches 50 degrees centigrade and turns itself off when the heatsink reaches 40-45 degrees centigrade. This allows for “silent running” when used at low vol- umes. Be sure to leave at least a 1/2" clearance between the vent on the left side of the Bass 350 and the side of any rack case or enclosure you should happen to install your amp in. This will allow for the heat generated by internal components to escape.

Setting the Fan Defeat Switch to the “Fan” position activates the internal cooling fan’s normal operating mode. Setting the Fan Defeat Switch to the “Defeat” position deactivates the cooling fan regardless of the internal temperature of the unit. For this reason, it is recommended that the Fan Defeat Switch be set to the “Fan” position for the majority of the time that the amplifier is in operation. Please note that it is normal for the cooling fan to be audible at low levels. We recom- mend deactivating the fan only in situations where the noise floor is so low that normal fan noise might be noticeable or distracting, such as recording situations where a microphone is used in close proximity to the unit.

POWER ON/OFF SWITCH

Setting the Power On/Off switch to the “On” position switches on the Bass 350. The power LED will light up. Setting the Power On/Off switch to the “Off” position switches off the unit.

LIMITER/COMPRESSOR CIRCUIT

The Limiter found in the Bass 350 is a soft knee type limiter. The Limiter circuit is located after (post) the Master Volume and before (pre) the power amplifier. Therefore, the limiter is driven by the Master Volume. Its threshold (starting point) is preset by the factory so that the user can get maximum overall apparent volume without unduly overdriving the power amplifier or internal speak- ers. This can be helpful in preventing speaker damage when running your system at high volume. You may either activate or defeat the limiter via the Effects Blend Control. The “In” position acti- vates the Limiter Circuit. The “Out” position defeats this feature.

LIMITER ACTIVE LED

When the threshold (starting point) of the Limiter Circuit is reached, the Limiter Active LED will light, indicating that the Limiter Circuit is active. The Limiter LED will be inactive when the Limiter is defeated or when playing at lower levels.

BASS 350 USER GUIDE 5

350 specifications

The SWR Sound 350 is a celebrated bass amplifier renowned for its powerful performance and user-friendly features. Designed for both professional musicians and hobbyists, this amp caters to a wide range of musical styles, making it a versatile choice for bassists.

One of the key features of the SWR Sound 350 is its impressive power output. With 350 watts of peak power, the amp ensures that players can achieve the loudness and clarity necessary for various venues, from intimate clubs to large concert halls. This power is complemented by a robust speaker cabinet that can handle the low frequencies without distortion, allowing bassists to dive deep into the music without losing punch or definition.

The SWR Sound 350 is equipped with advanced tone-shaping controls, which include a three-band EQ. This allows players to sculpt their sound according to their specific needs. The bass, mid, and treble knobs give users the flexibility to fine-tune their tone, whether they aim for a deep, smooth low-end or a bright, cutting high.

Another standout feature is the built-in limiter, which helps to prevent signal clipping and ensures that the output remains clean, even at higher volumes. This technical innovation allows players to push the amp to its limits without fearing distortion, providing peace of mind during performances.

In terms of connectivity, the SWR Sound 350 offers a range of options, including a balanced XLR output for direct connection to PA systems. This feature is exceptionally beneficial for live performances, as it allows for an uncolored, direct signal that preserves the amp's character. Additionally, there are multiple inputs for different instruments, making it easy for musicians to switch between bass guitars or even utilize a variety of effects pedals.

The chassis design is also noteworthy. Built with durability in mind, the SWR Sound 350 features a rugged outer casing that can withstand the wear and tear of frequent transport. The lightweight design makes it easy to carry around, while still maintaining a robust sound quality that players can rely on.

In summary, the SWR Sound 350 is a powerful and versatile bass amplifier that combines robust performance with user-friendly features. Its impressive wattage, advanced tone controls, built-in limiter, and multiple connectivity options make it a top choice for bassists looking for reliability and sound quality in one compact unit. Whether for practice, recording, or live performance, the SWR Sound 350 stands out as an essential tool for any serious bassist.
