WOHLER IAM1-8 AUDIO MONITOR 8-channel, 3G-SDI/analogue, 5W RMS per side, 1U

AMP1A PLUS

Wohler AMP1A Plus audio monitor is a self-powered, stereo audio monitoring of two analogue channels (1x stereo channel). AMP1A Plus contains four transducers driven by three power amplifiers. One amplifier/driver combination handles midrange and high frequency information in stereo, while the second handles summed low frequency information below the 500Hz crossover point.

The design provides focused sound for operators in a near field of 1-3ft. The speaker output is 5watts RMS per side, 10watts peak; with RMS bass of 10watts continuous/20watts peak. Peak acoustic output is rated at 98dB SPL at 2ft. Extended high frequency response reveals potential problems with audio whine or hiss. Electronic rather than acoustic cancellation of bass frequencies provides positive audible detection of out-of-phase (reversed polarity) audio feeds.

A 6.35mm headphone jack with associated volume control is positioned on the front facing panel. When the headphone output is in use, the speakers are muted automatically. All audio I/O connectivity, including loop-through, is by way of 3-pin XLR connectors.

Power consumption: 35W. Power requirements: 100-240 VAC ±10%, 50/60Hz. Dimensions (WxHxD): 483 x 44 x 254mm. Weight: 4.6kg.

AMP1-DA/106

AMP1-DA/106 is a self-powered, 2-channel audio monitor analogue and AES/EBU digital sources. 106 segment LEDs add visual monitoring. This audio monitor is suited for use in VTR bays, mobile production vehicles, teleconferencing installations, multimedia systems, satellite link and cable TV facilities, and on-air radio studios.

The design provides focused sound for operators in a near field of 1-3ft. The speaker output is 5watts RMS per side, 10watts peak; with RMS bass of 10watts continuous/20watts peak. Peak acoustic output is rated at 98dB SPL at 2ft. Extended high frequency response reveals potential problems with audio whine or hiss. Electronic rather than acoustic cancellation of bass frequencies provides positive audible detection of out-of-phase (reversed polarity) audio feeds.

A tri-colour LED design allows a variety of options such as phase correlation, peak hold, and alternate scales. The standard display mode is set as a single segment PPM “dot” above a VU bar; each segment’s colour is fixed according to its position on the scale. Level calibration may be set via dip switches to select one of four different calibration levels.

A 6.35mm headphone jack with associated volume control is positioned on the front facing panel. When the headphone output is in use, the speakers are muted automatically. Other than the headphone output on the front facing panel, all I/O connectivity is on the rear facing panel; including 2x unbalanced BNC AES/EBU digital inputs, 2x balanced 3-pin XLR analogue inputs (1 stereo), and 2x balanced 3-pin XLR analogue output of selected source.

HRS-1S

Wohler HRS-1S is a 2-channel, self-powered audio monitor with two analogue input channels on 3-pin XLR, and a stereo loop-through. The unit contains two transducers that driven by two power amplifiers: one amplifier/driver combination handles midrange and high frequency information, while the second handles summed low frequency information below the 500Hz crossover point. This results in a speaker output of 5watts RMS per side, 10watts peak; 10watts RMS continuous bass, and 20watts peak.

The half-1U rack design allows this unit to fit into smaller spaces whilst providing focused sound for operators in an ultra near field (1 to 3 ft.) working environment, with a peak acoustic output of 95dB SPL at 2ft.

Extended high frequency response reveals potential problems with audio whine or hiss. Electronic rather than acoustic cancellation of bass frequencies provides positive audible detection of out-of-phase (reversed polarity) audio feeds. A 6.35mm headphone jack is provided on the front panel, and usage automatically mutes the speakers. Output limiter circuits are incorporated to protect the speakers, and magnetic shielding allows placement immediately adjacent to video monitors with no colour distortion.

Included accessories: RE-1 rackmount kit
Optional accessories: RE-2 centre rackmount kit, RE-3 side-by-side rackmount kit

Power consumption: 35W Typical. Power requirements: 24V DC, 3.0 A, with external power supply connecting to
100-240VAC, 50/60Hz mains power. Dimensions (WxHxD): 216 x 44 x 190mm. Weight: 3.2kg.
