Remote Audio 15V Juicer. Regulated isolating power cable; 15V, 25W, 1.7A. 4-Pin XLR Male to 4-Pin XLR Female.
The Remote Audio Juicer provides a regulated output of 15VDC when its input voltage is between 9VDC and 18VDC. Using the Juicer between your battery and certain equipment will allow you to operate longer before having to change or recharge your external battery.
The Juicer is intended for use with external battery supplies such as common lead-acid types that still have useful current available even after the battery has discharged below 12 volts.
It is common for modern electronic equipment rated at a nominal voltage of 12VDC to be able to accept a voltage range as low as 10V. (The minimum operating voltage can usually be found printed on the equipment or in the manual.)
However, some equipment will cease to operate at voltages lower than your battery is putting out. For instance, the Fostex PD-4 will not operate reliably when the external voltage drops below 11VDC, even though your battery supply may still have plenty of useful current remaining and your other equipment continues to operate. Another example are the Cooper 106 and 108 mixers that need at least 15 volts for full spec. The 15 Volt juicer will always output 15 volts even when the supply voltage is as low as 10 volts.
The Remote Audio Juicer cable has two uses:
- First, it isolates the power source from the device being powered, interrupting potential noise-causing power loops.
- Second, the Juicer provides a regulated output of 15VDC (which is particularly important for the popular Cooper 106 and 108 mixers) even when the battery or power supply feeding it goes as low as 9VDC.
Most modern equipment used in field audio today has a relatively wide operating voltage range, typically between 10VDC and 15VDC. If your power supply output voltage is within this range, then the Juicer is not required as a voltage regulator. However…
A word about the popular Cooper 106 and 108 mixers and their voltage requirements: The still commonly used Cooper 106 and 108 mixers require a minimum of 14VDC to produce a full 48V phantom power for condenser microphones (otherwise resulting in premature microphone clipping and excessive microphone self-noise). Therefore, when using a 12VDC power supply or battery to power these Cooper mixers, the Juicer cable, which outputs 15VDC, is highly recommended. When the input voltage of the Cooper 106 and 108 mixers is at least 14VDC, full performance specs are achieved, and there is no advantage or disadvantage of higher voltages such as 18VDC or 24VDC.
A word about power system noise: Powering multiple pieces of equipment with a single power source is becoming more and more common for professional field audio systems. Depending on the internal power supplies of audio equipment, and how the audio inputs and outputs of these various devices are connected to each other, loops can occur that create audible noise in the audio signals. The Remote Audio Juicer cable can interrupt these power loops by isolating the power source from the device being powered, thus eliminating the noise caused by sharing a single power supply.
The maximum capacity of the Juicer cable is 30W (2A @ 15V). It is generally not recommended to power more than one device with each Juicer cable.
