impedances for the MIC input. The effect varies depending

 

on the microphone used. With dynamic microphones, a lower

 

impedance setting will also reduce the input level—this effect is

 

less pronounced with good condenser microphones. We recom-

 

mend the 10 k (Ω) setting for most applications, although some

 

microphones may benefit from a different setting.

PHANTOM

The GainStation 1 provides 48-Volt phantom power for micro- phones requiring external current (generally condenser micro- phones). Such microphones are dependent upon a clean, consis- tent and noise-free power supply for optimal operation and audio quality. The GainStation 1 continuously delivers precisely 48 V and a maximum of 14 mA, which will power all micro- phones.

IMPORTANT NOTE: All microphones with balanced, ground-free outputs, including tube microphones, can be used with the phantom power activated. First connect the microphone to the GainStation 1, then activate the phantom power. When finished, first deactivate the phantom power and wait at least 30 seconds before disconnecting the microphone to allow residual current to discharge.

Phantom power should only be activated when using micro- phones that require it. Please be sure to deactivate phantom power with all other microphones. Unbalanced microphones may only be used with phantom power deactivated.

The 48V LED illuminates to indicate activated phantom power. When deactivating phantom power, it can take several seconds for the LED to go out, since the 48-V current dissipates rather slowly. When changing microphones, you should wait until the LED is completely dark before re-patching.

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.
