SSL SiX Channel 500 Series Channel Strip

It sounds like you’re describing the features and specifications of the SiX Channel Strip (SiX CH) by SSL (Solid State Logic), which is a 500 Series channel strip module designed to offer high-quality audio processing in a compact form factor. Let’s break down the key features and terms mentioned:

SuperAnalogueTM Mic Pre:

This is a high-quality microphone preamplifier that offers a wide gain range and low noise. SuperAnalogue technology is known for its clean, fast, and punchy characteristics, making it suitable for various types of audio sources.

SSL HF and LF EQ:

The SiX CH comes with a two-band EQ inspired by SSL’s classic design. It features high and low shelving filters at 3.5 kHz and 60 Hz, respectively, with a gain range of +/-15 dB. Each band can be switched between shelving and bell curves, providing different shaping options. The bell curves also have the flexibility to operate at 5 kHz and 200 Hz.

Channel Compressor:

The SiX CH includes a compressor with a single knob control. Despite its simple appearance, this compressor is designed to offer powerful and versatile performance. It uses SSL’s feed-forward circuit design, with program-dependent attack time and automatic make-up gain to maintain a consistent signal level.

TRS Line Input:

The front-facing TRS line input provides a convenient way to connect instruments on the go. The SiX CH can also be used as a summing module, adding a level of versatility. The input impedance can be changed using the Hi-Z switch, with options for both 10 kΩ and 1 MΩ. The latter setting is suitable for high-impedance sources like passive guitar pickups, eliminating the need for an external DI box.

Tech Specs:

The module processes mono signals. The preamp gain is variable, with a range of +6 to +72 dB for microphones and -3 to +63 dB for line-level sources. The mic pre Equivalent Input Noise (EIN) is typically 129dB, indicating its quiet operation. The Total Harmonic Distortion plus Noise (THD+N) is less than 0.0015%, highlighting the module’s commitment to maintaining audio fidelity. Common-Mode Rejection Ratio (CMRR) is greater than 80dB for microphones and greater than 70dB for line-level sources, which suggests effective rejection of unwanted common-mode interference.

In summary, the SiX Channel Strip appears to be a high-quality audio processing module designed for various recording and mixing applications. It offers a combination of a pristine mic preamp, versatile EQ, and a deceptively simple yet effective compressor, making it a potentially valuable tool for audio professionals seeking premium sound quality in a compact format.
