AM-2B

 

AM-2B - the complete tool for all stereo audio applications. Real time monitoring of stereo audio phase and program average and peak levels in one affordable package. The AM-2B is a compact 2 EIA rack unit for use where space is at a premium.

A quick glance by the operator gives a complete "picture" of the stereo audio signal. Audio level monitoring, both Peak and VU and the B&B Systems Phase Monitor, allow you to easily avoid out-of-phase stereo signal and prevent peak audio distortion.

 FEATURES:

  • B&B Systems Phase Monitor CRT X/Y display with calibrated VU meters and Peak meters for each channel.
  • ANSI calibrated VU meters and Peak meters for each channel.
  • Self-contained in only 2 EIA rack units.
  • Magnetic and EMI/RF Shielding.

 

 

  SPECIFICATIONS:

SIGNAL INPUTS:
AUDIO: Three pin XLR female for left and right audio. All inputs are balanced and buffered with greater than 50k ohm input impedance. Inputs can be set for resistive termination according to studio operating standards.

DISPLAY:
SCOPE: The VU meters meet all electrical and ballistic specifications established by the Bell Laboratories and ANSI 16.5-1954, as required by broadcasting and sound engineers.
LED PEAK METERS: Peak reading, full wave rectified, read both positive and negative peaks, 250 microsecond rise time; 300 millisecond fall time.

POWER: 115-120/220-260 VAC, 50/60 HZ, 75 Watts max.

PHYSICAL: 3 1/2"x 19" Wide x 17" Deep, 2 EIA rack units, 20Lbs. (9 Kilo).
