Anthem STR Integrated...$4499.00 MC/MM Phono Stage with:
RUMBLE FILTER
Use this with a turntable to reduce or eliminate low-frequency noise below the music spectrum. Rather than rolling off all content including the music, the filter acts only on vertical stylus motions that are inherently not part of the music signal. This is especially effective with warped records that cause excessive or non-musical woofer motion. Select a frequency from 10 to 60 Hz in 1 Hz increments. To disable the filter, select Off.
PHONO EQ
The Phono EQ, Bass Turnover, Bass Shelf, and 10k De-Emphasis controls allow the proper equalization of records that predate the RIAA equalization standard. If no records in your collection were manufactured before the 1960s, you can skip the rest of this section. To make record grooves manageable, bass is reduced when records are manufactured, while the treble is emphasized. The main function of a phono preamp is to reverse this equalization upon playback, restoring the intended frequency response. The problem is that before the record industry settled on an equalization standard, resulting in the RIAA curve during the 1950s, the amount of reduction and emphasis varied requiring multi-curve phono preamps for proper playback. Today, such phono stages are rare. This means that if a phono stage that was designed for only one kind of record is used to play older mono records, there will be too much treble, midrange, or bass, or not enough of it. These menu settings give you the ability to play all old records with their intended frequency response:
BASS TURNOVER – the frequency at which 3 dB boost occurs. In this example, it is 500 Hz: 10K DE-EMPHASIS – the attenuation at 10 kHz. In this example, it is -13.7 dB: 16 The following curve combines the two above and adds BASS SHELF or boost limit at 20 Hz, which is 20 dB in this example: The graph above represents the RIAA playback curve. Older phono curves use other amounts of bass boost, bass shelf, and treble cut, often expressed in this format: 500R-13.7 where 500 is the bass turnover in Hz, -13.7 is the 10 kHz de-emphasis in dB, and R is the bass shelf according to: N (None), R (20dB), B (18dB), A (16dB), C (14dB), X (12dB). When Convert Analog is set to 32/192, the following Phono EQ options become available: 500R-13.7 (RIAA) 400N-12.3 (AES) 350N-10.5 (CCIR) 500B-16 (NAB) 400N-12.7 (Capitol LP) 500C-16 (Columbia LP) 500C-10.5 (London LP) User Select according to the record that you are playing. For pre-RIAA long-playing records, check whether the jacket indicates “AES”, “CCIR”, “NAB”, etc. You can also check one of several web sites which provide code lists according to record label and year. They can be found by searching the web for 500R-13.7 or playback equalization for 78 rpm shellacs and early 33-1/3 LPs – don’t forget to use a properly sized 78 rpm stylus if playing 78 rpm records. To create or fine-tune any curve, select User and enter Bass Turnover, Bass Shelf, and 10k De-Emphasis according to the code list, or adjust by ear – it’s like using bass/treble controls except that these are specially made ones for phono.
BASS TURNOVER options are None, 150, 180, 200, 250, 280, 300, 350, 375, 400, 450, 500, 600, 629, 700, 750, 800, and 1000 Hz. The 10K DE-EMPHASIS adjustment range is from -25.5 dB to None in 0.1 dB increments. Although the purpose of these controls is to provide the correct response with old records, you might find similar uses, for example to brighten a muffled-sounding stereo LP, or to add weight to a thin-sounding one. This is fine as long as extreme settings that would result in overload or a distorted sound are avoided. Each virtual input stores its own curve settings. This way, you can create multiple profiles for your turntable input, each using a different curve according to the records in your collection.
- Six pre-RIAA curves plus adjustable settings for playing older records accurately
- Adjustable Rumble filter
- Complete Analog Bypass if you don't want any active DSP - all configurable in the Input Settings.
- Assignable Inputs if you have multiple record labels with different EQ Curves. Simply change the input according to which record label you're playing. Ultimately up to 30 virtual inputs total.
