The full-featured PRESSPOWER 2 is the successor to our original
PRESSPOWER unit, the standard for press conferences worldwide.
It features 2 mic/line inputs with individual gain controls and 16 transformer isolated outputs that are individually switchable for mic or line level operation. The PRESSPOWER 2 includes a 20-segment LED level meter, an internal test tone generator, a built-in headphone monitor amp with volume control, high-pass filters, and phantom power -- all conveniently front-panel accessible. The high-performance input stage provides clean audio even in high RF environments. The unit can be powered by 115/230VAC - 50/60Hz, by (4) 9V internal batteries or with an external DC supply (12 - 36VDC) connected via rear terminals. This allows the unit to be powered by a car battery, cigarette lighter, camera pack battery, etc. The unit will automatically switch to DC back-up power in the event of an AC power interruption. Additional active mic/line outputs can be added with optional 16 channel PRESS2XP expander module, giving you up to 48 total active outputs. Additional mic outputs can be achieved by adding passive PB Series Press Boxes to outputs set to line level.  PRESS2XP Active Expansion Module   PRESS CASE The PRESSPOWER 2 is available without the padded case (PRESSPOWER 2 NC) and it mounts in a standard 4 space, 19" rackmount. Its case is also available separately (PRESS CASE, pictured above). |

PRESSMITE
ACTIVE PRESS BOX Made in Rochester NY, USA
This compact, active press feed distribution box distributes 12 high-quality mic level signals and 2 line level signals with a high degree of isolation between outputs. It provides a 60dB gain adjustment for one mic or line input. The PressMite also features a built-in headphone amp. Two alkaline 9V batteries provide power for typically more than 8 hours of continuous operation, monitored by a Battery OK LED. The batteries are easily replaced via side-mount trays. A 120VAC/24VDC power adapter (model PS24) is included. In MIC input mode, 18V phantom power is selectable and a three segment LED headroom display speeds level adjustment. If more outputs are needed, PB Series Press Boxes can be connected to the line outputs to provide up to 48 additional mic outputs. The PressMite's box is built to withstand the abuse of public events. Frequency Response: 100Hz-6kHz ±0.3dB, 15Hz-20kHz ±3.0dB Input Impedance: Mic: 1.5k Ohms; Line: 40k Ohms Max Input Level: Mic: -14dBu; Line: +30dBu Output Impedance: Mic: 150 Ohms; Line: 600 Ohms Max Output Level: Mic: -17dBu Mic Outputs; Line: +12dBu Total Harmonic Distortion: 0.063% at 1kHz (unity gain) Rise Time: 26µS Phase Shift: -0.8° at 1kHz (unity gain) Intermodulation Distortion: 0.08% (unity gain, Mic mode) CMR at 60Hz: Mic: 75dB; Line: 60dB Isolation: Mic Outputs: 65dB between vertically adjacent channel pairs, 107dB between non-vertically adjacent pairs Line Outputs: Greater than 77dB Power Requirements: (2) 9V alkaline batteries or 24 Volt external DC (120VAC/24VDC power adapter included) |

PB SERIES
PASSIVE PRESS BOXES Made in Rochester NY, USA
The PB Series expands mic outputs when used with line outs on PRESSPOWER 2 or PRESSMITE active press boxes or any time a line level feed is available. These passive units distribute one line level input to multiple mic level outputs*. Each output is transformer isolated, provides excellent interchannel isolation and is ground lifted to help eliminate noise problems. Whirlwind TRSP-2F transformers are used throughout. The boxes are constructed with rugged, cold-rolled steel. Available with 6, 12, or 24 outputs. Input Impedance: 2k Ohms Output Impedance: 150 Ohms Operating Level: 0dB input = -43dB output Channel-to-channel Isolation: 65dB between vertically adjacent channel pairs, 107dB between non-vertically adjacent pairs * Line level signal MUST be provided into these passive press boxes. A microphone directly into the input will not provide enough signal level for proper operation.
