Changing Batteryxxxxxxxxxxxxxxxxxxxx

By putting the two handles at the bottom together the battery cassette is released and the battery can easily be pulled out. A new battery is pushed all the way into the generator and is locked by directing the handles away from each other. When changing the battery it must be mounted in a battery cassette by an authorised service station.

Connecting Lamp Heads

One or two lamp heads can be connected to the lamp head sockets A & B [1]. When connecting the lamp head plug, align the dots on the plug with the white dot on the generator panel. Secure by turning the locking ring on the plug clockwise.

Energy Control

The energy output is regulated over eight f-stops. The energy can partly be adjusted with the control POWER [16] in 1/2 f-stop increments, from 1/1 down to 1/16 of the total energy (equivalent to ﬁve f-stops) and also via the POWER dial (15) for ﬁne-grained energy control in 1/10 f-stop increments and partly with the SYM/ASYM switch [2] and through the use of one or two lamp heads.

One lamp head: The total energy chosen is obtained if the lamp head is connected to A and the SYM/ASYM switch is at A 1/1(1/2), B 1/2. The lamp head can be connected to socket A or B. If the lamp head is connected to A the total energy

obtained is chosen with the control POWER [15,16]. If the lamp head is connected to B half the energy is obtained if the SYM/ASYM switch is in position A 1/1 (1/2), B 1/2. If the switch is in the position A 1/2, B 1/4 a quarter of the chosen energy is obtained. Two lamp heads: The energy chosen with the POWER [15,16] control can either be distributed evenly through the two lamp heads (the SYM/ASYM switch in the position A1/1 (1/2), B 1/2) or twice

as much energy (equivalent to one f-stop ratio) through A as B (the SYM/ASYM switch in the position A 1/2, B 1/4). At any change of energy with the control POWER [15,16 ] the ready lamp [8] is put out. When the light is out, this is an indication that auto dumping or recharging is in progress.

Choice of Modelling Light

First set the MOD.LIGHT (13) to timer controlled or continuous The maximum modelling light is 250 W even if a ProHead/ProTwin with a 500 W halogen lamp is used. A ProHead or older heads - Pro-7, PB or PF - can be used. The modelling light is automatically dimmed down to max 2500 W regardless of the nominal effect of the modelling light. The efficiency (output) is higher when using a 100 or 250 W lamp. We therefore recommend using max 250 W lamps also in the ProHead. The modelling light is constant and does not vary with the energy chosen. If you wish to use a 250W lamp the ProHead or proTwin ﬂash head must be used since the built-in fan will work on Pro-B2. Do not use older heads with a 250W lamp.

Timer controlled

Pushing the button MOD.LIGHT [11] turns on the modelling light. To save the battery the modelling light is automatically turned off after 10 seconds or when triggering a ﬂash.

To have the modelling light stay on for a longer period of time push the button two or three consecutive times, which will give 30 and 60 seconds respectively. For every period of

20 seconds when the modelling light is turned on the battery capacity decreases by the equivalent of two ﬂashes at full energy.

Pro-B2 specifications

The Profoto Pro-B2 is a cutting-edge portable battery-powered flash system that has set new standards in the world of professional photography. Designed for photographers who need powerful and reliable lighting solutions on location, it combines portability with impressive performance.

One of the standout features of the Pro-B2 is its dual head configuration, allowing photographers to shoot with two flash heads simultaneously. This flexibility provides an output equivalent to 1200Ws, making it ideal for a range of shooting scenarios, from portraiture to fashion to weddings. With the ability to use multiple heads, photographers can seamlessly blend ambient light with flash or achieve dramatic lighting effects tailored to their creative vision.

The Pro-B2 has an exceptional recycling time that can be as fast as 0.02 seconds, allowing photographers to capture fleeting moments without the worry of slow flash recovery. This rapid performance is complemented by a consistent color temperature that ensures accurate skin tones and lighting consistency throughout shoots, a crucial aspect for any professional.

Another notable feature of the Pro-B2 is its built-in AirTTL technology, which allows for seamless wireless communication between the flash and the camera. This advanced system automatically adjusts the light output based on the selected camera settings, making it easier for photographers to achieve the perfect exposure without extensive manual adjustments. Additionally, the manual control option provides seasoned photographers with the flexibility to fine-tune their lighting setup according to their artistic needs.

The Pro-B2 is built for durability, featuring a robust design that can withstand the rigors of outdoor shooting. The built-in battery provides up to 200 full power flashes per charge, with an easy-to-read LCD screen displaying essential settings for quick adjustments on the go.

Moreover, the system is compatible with a wide range of Profoto light shapers, offering endless possibilities for creative lighting setups. Whether using softboxes, beauty dishes, or reflectors, the Pro-B2 enables photographers to sculpt light with precision.

In summary, the Profoto Pro-B2 is an exceptional tool for professional photographers seeking powerful, portable lighting solutions. With its dual head capability, rapid recycling times, AirTTL technology, and durability, it stands out as a premier choice for those who demand the best in lighting performance.
