The impulses in the pack have the necessary minimum frequency correction. Each impulse is a snapshot of a particular "cab/mic/preamp" combination. The positions of the Sennheiser e906 and the Lomo 19A19 are not always identical; in some impulses, the left speaker was used, while others took advantage of the right one. The most characteristic feature of the Lomo 19A19 is its wide frequency response resulting in a more "open" sound, while the Sennheiser e906 tends to be more focused.
For easier navigation, the name of each impulse reflects the position and type of the mic used.
Cab50+cone: A combination of one mic placed 50cm from the cab and another one aimed at the center of the speaker cone and placed 10cm from the grill cloth. The main mic (cab50) is prevalent in both impulses in this category. This pair of impulses gives the most realistic impression of the cabinet's sound in real life.
- 01 Orange JR212 cab50 L19 - cone e906: The Lomo 19A19 is the main mic here, while the Sennheiser e906 is aimed at the speaker cone. This impulse has a more open character and produces more low frequencies.
- 02 Orange JR212 cab50 e906 - cone L19: The Sennheiser e906 is the main mic here, while the Lomo 19A19 is aimed at the speaker cone. This impulse has a narrower and more focused frequency response.
Dome edge: This pair of impulses was recorded with a mic aimed at the edge of the protective dome and placed 10cm from the grill cloth. This is a well-balanced mic position for this cabinet, resulting in prominent low mids. Both impulses in this pair have a notable scoop at 1600Hz and a peak at 2400Hz with an otherwise neutral frequency response.
- 03 Orange JR212 dome edge L19: The Lomo 19A19's wide frequency response results in slightly scooped low mids.
- 04 Orange JR212 dome edge e609: The Sennheiser e906 has a more uniform response in the 300 - 2200Hz range in this position.
Cone45: This pair of impulses was recorded with a mic aimed at the center of the speaker cone and placed almost perpendicular to the cone (at a 45° angle towards the cab's body). Both impulses utilize the Marshall power amp's tone correction for the lows and highs, resulting in a notable mids scoop. However, the cabinet has an extra resonant peak in the 700 - 1000Hz range, which gives the sound a "nasal" quality and lets it punch through a busy mix.
- 05 Orange JR212 cone45 L19: The Lomo 19A19 has more open lows and highs, but its large membrane coupled with the close mic positioning results in additional scoops and peaks across the frequency range.
- 06 Orange JR212 cone45 e609: The Sennheiser e906 has a more focused sound in this position due to its narrower frequency response.
Center+cab50: This pair of impulses was recorded with a combination of two mics: one aimed at the center of the speaker cone and placed 5cm from the grill cloth, and the other placed 50cm from the cabinet. The closer (center) mic is prevalent in both impulses, resulting in the brightest sound quality. Just like the previous pair, this one uses the Marshall power amp's tone correction for bass and presence boost.
- 07 Orange JR212 center L19 - cab50 e906: The Lomo 19A19 is aimed at the center of the speaker, while the Sennheiser e906 is the main mic.
- 08 Orange JR212 center e906 - cab50 L19: The Sennheiser e906 is aimed at the center of the speaker, while the Lomo 19A19 is the main mic. This impulse has a slightly more uniform frequency response in the 750 - 6000Hz range.
Сab45: These impulses were recorded with a mic aimed at the center of the cabinet at a 45° angle from a 30cm distance. This allowed us to capture another characteristic quality of the PPC212: its "fast" bass response. Just like the Cab50+cone pair, this one provides a true-to-life impression of the cab's sound due to the fact that both speakers were recorded simultaneously by the same mic.
- 09 Orange JR212 cab45 L19: The Lomo 19A19 has slightly more pronounced lows.
- 10 Orange JR212 cab45 e609: The Sennheiser e906 boosts the upper mids a little bit.
