0,00 kr.

The 12AR can be powered either by internal standard batteries or an external DC supply (4.5 V- 24 V), e.g. a mains/line adapter. It is built into a sturdy anodized aluminum cabinet.

The polarization voltage for the microphones fitted to the preamplifiers can be set to 0 V — for prepolarized microphones, or 200 V — for externally polarized microphones.

Design

The 12AR can be powered either by internal standard batteries or an external DC supply (4.5 V- 24 V), e.g. a mains/line adapter. It is built into a sturdy anodized aluminum cabinet.

The polarization voltage for the microphones fitted to the preamplifiers can be set to 0 V — for prepolarized microphones, or 200 V — for externally polarized microphones.

The 12AR also supplies ± 15 V to power the preamplifiers. It will run for approximately 30 hours on fresh standard alkaline batteries. A Low Batt LED indicates the condition of the batteries.

The inputs are two 7-pin LEMO sockets on the front panel, which are wired up for GRAS microphone preamplifiers, e.g. 26AB, 26AC, 26AJ, and 26AK, but is also compatible with other available makes of similar microphone preamplifiers.

The signals from the preamplifiers are AC coupled to the outputs which are standard BNC sockets also on the front panel.
