Limiter

Control elements

The GainStation 1 offers two types of output level limiting: PEAK and FET. The limiter is pre-output level control, so that the limited signal can be optimally adapted to the internal or external converter.

The peak limiter operates with special diodes that convert signal peaks into a type of saturation. Depending on the signal, this allows levels to be effectively and subtly limited. This type of limiting works very quickly, reliably limiting even microsecond- long transients, and is very effective for drums and percussion. The peak limiter also enables maximum loudness. Operation is displayed via the Limit LED.

The FET limiter is additionally available when the tube stage is activated. The FET circuit operates with a Field Effect Transistor (FET), which is connected to the tube and enables—always in conjunction with the peak limiter—a reduction of signal ampli- tude. Thus this limiter works in a similar fashion to a compressor, which makes it very effective for signals that undergo unfore- seeable level changes (i.e. vocals, speech, guitar, bass, piano etc.) and where minimum loss in signal quality is desired. The peak limiter is always active post-FET limiter to ensure reliable protection. The Limit LED also displays the operation of the FET limiter (always somewhat more calmly than with peak limiting).

IMPORTANT NOTE: If the tube stage is deactivated while FET limiting is active, the LED will continue to display in FET limiting mode.

For more information on using the limiters please see page 20, ”Limiter”.

2272, 2273 specifications

Sound Performance Lab (SPL) is renowned for its innovative audio equipment, and the SPL 2273 and 2272 are two standout products in their range. These units are designed to offer exceptional sound quality and versatility for both professional and home studio environments.

The SPL 2273 is a powerful channel strip that combines a microphone preamp, a compressor, EQ, and a creative feature set, making it ideal for recording and mixing applications. One of its defining characteristics is the impressive preamp section, which delivers clean, transparent gain and supports various input sources, including dynamic and condenser microphones. The preamp also features a high-pass filter, providing further control over unwanted low-frequency noise.

The 2273 includes an integrated compressor that excels in delivering smooth dynamics control. It offers a straightforward interface with adjustable threshold and ratio settings, giving users the flexibility to craft the ideal sound for their material. Its soft knee compression ensures that the transition into compression is gentle, preserving the musicality of the performance.

On the EQ front, the SPL 2273 boasts a powerful three-band equalizer with fixed frequencies, allowing for precise tonal shaping. This EQ can effectively cut or boost frequencies, enabling users to sculpt their sound with clarity and precision.

The SPL 2272, typically seen as a companion piece, is a versatile two-channel version of the 2273. It shares many of the same high-quality components and technologies but is focused on simplicity and efficiency. With its streamlined interface, users can quickly dial in the desired sound without getting lost in complexity.

Both models leverage SPL's proprietary technologies, including their unique 120V rail design. This approach allows for superior headroom and reduced distortion, ensuring that the audio signal remains clean and free from unwanted artifacts throughout the processing chain.

Together, the SPL 2273 and 2272 empower engineers, producers, and musicians to achieve professional-grade recordings with their comprehensive feature sets. Whether in a high-end studio or a smaller setup, these units deliver exceptional performance that stands out in today's competitive audio landscape. They embody SPL's commitment to quality and innovation, making them must-have tools for any serious audio professional.
