AD IN 2

If the optional 24/96 AD converter module is installed, this input can be used to convert an external analog signal. To avoid clip- ping, the input level should not exceed +12 dBu (+12 dBu corre- sponds to full digital gain of 0 dBfs). Excessive input levels are indicated by the AD OVL LED.

If no connection is made here, the output signal of the GS1 is routed to both channels of the converter.

TIP: AD IN 2 can also be used as an insert for external pre-conver- sion processing. Connect the analog outputs of the GainStation 1 to the external processor‘s inputs and the processor‘s outputs to AD IN 2 on the Gain Station 1. One channel of the converter output will contain the dry or unprocessed signal, while the other channel will contain the processed signal.

AD IN 1 MUTE

Channel 1 of the converter is internally connected to the analog output, so that the AD OVL LED is always active. If the converter is not being used, this connection can be bypassed via the AD IN 1 MUTE switch so that the LED does not continuously blink or illuminate.

TIP: If no converter is installed, this switch should always be activated.

DIG. OUT

The converted S/P-DIF signal is routed in parallel to the RCA and optical outputs. The signal is in professional format with no sample rate data in the status block.

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.
