Orange #4 Jim Root PPC212 Cabin Impulse Pack
Orange Jim Root PPC212 IR Pack – a set of 10 impulses (IR) from Shift Line that can be used with CabZone X\LE and Twin MkIIIS, as well as with any other hardware or software sound simulator office. The impulses were filmed and edited at the Shift Line studio in St. Petersburg. This set is the fifth in a series of cabinet impulses presented on our website, and contains the Orange Jim Root PPC212 cabinet impulses.

The pulses are prepared in mono 24bit 48kHz WAVE PCM1 format, without compression. The pulse length is 1000 samples (about 20 ms), which is sufficient to transmit a reliable frequency response of the cabinet without the influence of the room and additional spurious reflections. All dialing impulses are reduced in volume to the same value to eliminate the “louder is better” effect.
From the Authors:
The Orange Jim Root PPC212 cabinet was released by Orange as part of the James “Jim” Root (guitarist for Slipknot and Stone Sour) signature set. This is an enclosed cabinet made from 18mm thick birch plywood and equipped with two 12″ Orange Voice of the World speakers. The cabinet has the same dimensions as the PPC212OB (66 x 52 x 30 cm), but the closed design and different drivers give the sound its own character: fast and focused low-frequency response combined with a pronounced upper mids are perfect for modern styles. It is also worth noting that this cabinet produces excellent clean and slightly boosted sound, so its use is not limited to heavy music.

Orange has currently discontinued this cabinet, but we really like it and continue to work in the Shift Line workshop. That is why we have created a set of impulses that you can apply in your creativity. Each impulse is unique, despite the fact that they are all taken from the same cabinet model.

The pulses were recorded with two microphones: Sennheiser e906 and Lomo 19A19. When removing impulses, a Marshall power amplifier with tone correction for high and low frequencies was used. The set contains 10 pulses with different microphone positions, microphone combinations and balance between them.

Instructions for use:
Copy the pulses to the appropriate folders on the CabZone or Olympic MkIIIS SD card, having previously deleted the old files.

All impulses in the set are in 24bit 48kHZ WAVE PCM1 format without compression and are adapted to work with our devices: the A+ CabZone LE impulse cabinet simulator and the Shift Line Olympic MkIIIS tube preamplifier. Naturally, they can be used in any compatible device or application that supports this format.

Details about the files in the set:
The pulses presented in the set have the necessary frequency correction and represent a cast of a specific “amplifier/cabinet/microphone/preamp” combination. The positions of the Sennheiser e906 and Lomo 19A19 microphones are not always completely identical; In some of the impulses, the right speaker is used, and in others, the left speaker of the cabinet is used. Some of the pulses are a combination of these microphones installed in different positions. A common distinguishing feature of the Lomo 19A19 microphone is its always wider frequency response bandwidth (the sound is more “open”), while the Sennheiser e906 has a focused character.

The names indicate the position and type of microphone for quick orientation. And now – a more detailed description of each impulse.
The first pair of impulses is cab50+cone: a combination of a microphone located at a distance of 50 centimeters from the cabinet, and a microphone aimed at the center of the speaker cone at a distance of 10 cm from the protective grid. These impulses are dominated by the survey microphone (cab50), and are the closest to the actual perception of the cabinet.

01 Orange JR212 cab50 L19 – cone e906 – Lomo 19A19 general and Sennheiser e906 on the speaker cone. Has an open character and more low frequencies.
02 Orange JR212 cab50 e906 – cone L19 – Sennheiser e906 common and Lomo 19A19 on the speaker cone. Has a narrower frequency response range and more focused sound.

The second pair of impulses is dome edge: captured by a microphone aimed at the edge of the protective cap from a distance of 10 cm from the protective mesh. A balanced position for this cabinet, emphasizing the lower mids. In both cases, the dip at 1600 Hz and the peak at 2400 Hz are clearly audible with an overall neutral frequency balance.

03 Orange JR212 dome edge L19 – Lomo 19A19 with wide response in frequency response. Slightly less than lower middle.
04 Orange JR212 dome edge e609 – Sennheiser e906 in this position has a smoother response in the range of 300-2200 Hz.

The third pair of impulses is cone45: taken with a microphone aimed at the center of the diffuser almost perpendicular to the cone (about 45° relative to the cabinet body). This pair of impulses was captured using a Marshall amplifier with added presence and bass and has a significant midrange rollover. However, the cabinet has an additional resonance in the range of 700-1000 Hz, which adds a characteristic “hundiness” and allows the sound to be readable even in a dense mix.

05 Orange JR212 cone45 L19 – Lomo 19A19 is classically more open in the lower and upper frequencies, but the close placement of a microphone with a large membrane in this position adds dips and resonances to the frequency response.
06 Orange JR212 cone45 e609 – The Sennheiser e906 sounds a little more balanced in this position due to its smaller frequency coverage.

The fourth pair of pulses is center+cab50: a combination of a microphone aimed at the center of the protective cap of the diffuser at a distance of 5 cm from the protective grid, and a microphone located at a distance of 50 centimeters from the cabinet. These impulses are dominated by the near microphone (center) and have the most “bright” sound. Like the previous pair of impulses, these were captured using Marshall amplifier equalization with added presence and bass.

07 Orange JR212 center L19 – cab50 e906 – Lomo 19A19 in the center of the speaker and a review Sennheiser e906.
08 Orange JR212 center e906 – cab50 L19 – Sennheiser e906 in the center speaker and overview Lomo 19A19. This pulse has a slightly flatter frequency response in the 750-6000 Hz range.

The fifth pair of impulses is cab45: captured with a microphone aimed at the center of the cabinet at an angle of 45° relative to the body from a distance of 30 centimeters. Thus, it was possible to emphasize another characteristic feature – “fast” bass. This pair, like the first, well conveys the real perception of the cabinet when playing due to the fact that both speakers are removed simultaneously (into one microphone).

09 Orange JR212 cab45 L19 – Lomo 19A19 has slightly more pronounced low frequencies.
10 Orange JR212 cab45 e609 – Sennheiser e906 slightly emphasizes the upper midrange.
