This is an CCIR Recorder and the strode roller is 50 Hz, S/N 813

1972 saw the adaptation of the popular IV-S into the IV-SJ. This was an instrumentation recorder for noise and vibration measurement and other scientific audio analysis organisations. Equipped with special microphone preamplifiers, modulometer and stepped input attenuators the IV-SJ is used for a multitude of different environmental and industrialization applications. Customers for the IV-SJ varied from NASA to Rolls Royce and Greenpeace.

The machine is Serial No. 813 with the following features:
This machine has two microphone inputs and 2 line inputs, switching between microphone and line inputs on each channel, 3 speeds-38, 19, 9.5cm/s (15-7.5-3.75ips). Monitoring selector with monitor speaker, 1Khtz. Reference generator, a Bias Switch for tape type, Recording Limiter, Low Frequency Attenuation, silicon rubber pinch wheel and drive belts, Direct /Tape monitoring and PPM metering with red for left and green for right channel meter needles with light, Monitoring selector with monitor speaker and level control or headphone monitoring with level control, Recording Limiter,
1K/8k Hz. Reference generator set at -8dB, tape head screen cover, This recorder is CCIR record and playback

PLEASE NOTE, there is no mono switch in the headphones or in the line and no NAB playback switch

These recorders have separate record and playback heads, so when you are recording you can monitor the input signal (DIRECT) or the off tape (TAPE) signal that has been recorded, this confident monitor switch saves you from having to keep playing the tape back to check the recording. If recording from an open microphone it is best to use closed headphones, like the Sennheiser HD25 when monitoring of tape, or you will hear the direct and of tape signals and you could get feedback

ABOVE LEFT, THE CHANNEL CONTROLS WORK THE SAME WAY AS AN IV-S RECORDER, BUT THE LARGE CONTROL IS A SWITCH IN 10 dB STEPS AND THE ONE BELOW IS A STANDARD POT FROM 1 TO 10 dB, THE FILTER SWITCH LIN IS SET FLAT, HP IS A BASE ROLL OFF AND YOU COULD USE C FOR DIALOG RECORDER, BUT A B & D HAS NARROW PEAKS AT ABOUT 1.K, 4.K AND 8K ARE NO SUITABLE FOR MUSIC RECORDER

Above from left to right, stereo output socket on 7 pin Binder plug, channel 1 & 2 line inputs on 7 pin Binder plugs, 2 x 5 pin XLR microphone 1 & 2 inputs, an adapter leads to 3 pin XLR are available, above them the gain controls for the microphone inputs.

A stereo output lead and a microphone adapter lead is supplied free with this recorder.

There is minimal head wear on the machine and it is setup and biased for AGM SM911 that is close to AGFA, ZONEL, BASF 468 tape and the sound quality and levels between direct and off tape are identical. A roll of AGM tape is supplied with this recorder, this roll of tape has been used to adjust the Bias, EQ and levels, it now has a test tone, and some music recorder on it, for you to test the recorder.

Above, you can see in the PILOT IN socket, with the pilot link plug fitted, this is only needed if the CRYSTAL PILOT GENERATOR A26 BOARD

is fitted, and when you don't need pilot sync, just remove this link plug so switch it off. see A26 below.

(Batteries and ATN power supply are not supplied with this recorder but are available from Ex Pro Recorders part of mike harris sound services.

ABOVE RIGHT, WITH OUT THE SCREEN COVER OVER THE CIRCUIT BOARDS, YOU CAN SEE THE SILVER COVER ON THE MICROPHONE POWERING AMP, FOR THE HIGH VOLTAGE MICROPHONES USED FOR INSTRUMENTATION RECORDER, IF YOU ARE GOING TO USE IT AS A STANDARD IV-S MUSIC RECORDER ITS BEST TO REMOVE THIS UNIT AS IT TAKES A LOT OF POWER FROM YOUR BATTERIES, YOU CAN STILL USE THE DYNAMIC MICROPHONE INPUTS, SEE LEADS

ABOVE LEFT, I HAVE ADDED A CRYSTAL PILOT GENERATOR A26 BOARD AND A PILOT SYNC PLUG IN THE PILOT SOCKET, ON THE RIGHT HAND SIDE OF THE RECORDER, SO YOU CAN LOCK SYNC TO A CAMERA OR USE A QSV-2 SPEED CONTROL, BUT IF YOU DON'T NEED TO SYNC TO A CAMERA, I CAN REMOVE THE A26 BOARD AND PILOT LINK PLUG AND TAKE £65 OFF THE PRICE OF THE RECORDER AND THE 3RD TRACK CAN BE USED FOR SOMETHING ELSE

I CAN SUPPLY MICROPHONE INPUTS LEADS THAT PLUG INTO THE 5 PIN XLR SOCKETS.

ALSO A BM11 MIXER LEAD THAT PLUGS INTO THE 5 PIN XLR MICROPHONE SOCKETS, SEE LEADS ON THIS WEBSITE

I NOW HAVE A IV-SJ IN STOCK THAT USES 8 PIN LEMO PLUG FOR MICROPHONE INPUTS, SO I WILL BE MAKING UP LEADS FOR THAT SOON.
