Crane Song Syren bundled with a Falcon and Insigna in a Lunchbox API 500-6B
The Crane Song Syren is a classic sounding tube preamp in a 500 series package, using a dual triode circuit with a 12AX7 tube.
Syren features a dual gain stage circuit and allows overdrive effects.
A switch selectable HI-z input is included. The low cut filter is at 90 Hz and is 24 db/ octave. The pad has -15 db and -25 db settings to allow a wide input range of signals.
The audio path color is changed by modifying the second stage tube circuit so it has negative feedback or does not have negative feedback. This changes the interaction between the tube stages and thus the sound of the pre-amp. With negative feedback it is a more accurate audio path with wider frequency response and without negative feedback it has a more open warmer sound.
The Crane Song FALCON is a fully featured classic sounding tube compressor in a 500 series package.
FALCON features 3 attack and 3 release time settings, hard and soft knee choices for compression or limiting, two different audio path sounds, wet-dry mixing for parallel compression, and is linkable.
The audio path color is changed by modifying the tube circuit so it has negative feedback or does not have negative feedback. This along with the optical like quality of the compressor allows for a colored vintage sound or a much cleaner sound with optical characteristics.
When linked the master unit controls all functions on the slave except for wet-dry and make up gain. The link system is capable of doing 5.1
The Cranesong Insigna is a 500-series module tube EQ designed by Dave Hill and comes from a long line of industry standard, high quality audio hardware.
The unit is based around a dual triode circuit with a 12AX7 tube, featuring 2 shelving EQs, a paramet-ric band and a low and high pass filter set.
The filters are both 24 dB/Octave with 7 frequencies each.
The high and low frequency bands are both shelving with 8 frequencies a piece.
The mid frequency band is a peak EQ containing 8 frequencies.
All three bands employ buffered RC circuitry in the negative feedback path around the tube amps.
The output stage features a shielded Lundahl high level line output transformer, all the stepped fre-quency pots are high quality Grayhill series 56 Rotary Switches and Bourn pots for the gain.
Let's have a closer look at the frequency ranges you'll get to work with.
The high pass filter ranges from 25 Hz to 150 Hz (25 - 40 - 50 - 60 - 90 - 120 - 150) and the low pass filter from 6kHz to 20 kHz (6 - 7.5 - 9 - 10.5 - 12 - 15 - 20).
The filters will give you enough power to clean up low rumble, tidy up the low end on LF centric instruments and control harshness at the top like guitars for example. We'll cover some more application examples a little further on in the manual.
The HF shelf gently ranges from 3.2 kHz to 20kHz (3.2 - 5 - 8 - 10 - 12.5 - 15 - 20) with the addition of an ultra high AIR band centred around 40kHz.
On the other side of the spectrum, the LF band shelves from an extremely low 10 Hz up to 200 Hz.
Straddling the middle, the MID peaking band deals with anything from 150 Hz to 7.2 kHz and is centred around a proportional Q (bandwidth). All three bands give you +/- 12 dB boost and cut.
The API 500-6B, also commonly called "lunchbox" is a 6-slot rack designed to accept all API standard 5.25" X 1.5" modules.
The lunchbox has an internal power supply with a rear panel selected AC voltage switch and a removable power cord. The input/output jacks are XLR. The lunchbox comes standard with a +48 volt internal phantom power supply, bussed to pin 15 for interface with the API 512c Mic Preamplifier.
Other uses for the versatile lunchbox include:
Multi-track recording of acoustic and electronic audio sources
Sound reinforcement systems and recording to multi-track formats
Multiple facility projects where portability is a plus
Broadcast and audio for video production
Custom channel input strips
