The model CL-1 is the latest AES/EBU monitor developed by Vancura Innovations to aid in remote monitoring of digital audio streams. A lightweight, battery operated, hand-held unit designed to provide engineers with lab-quality quantitative data anywhere at anytime. The CL-1 is designed to display the following characteristics:

• RF signal strength
• VU Meters for Audio Level
• Signal at exactly 20dBFS
• Signal polarity
• AES or Audio Indicator.

The CL-1 analyzes the incoming digital data and never requires any calibration. The unit operates from an internal DC-DC converter powered by 2-AAA batteries. Long battery life is insured by the ability of the CL-1 to operate down to 1VDC input power. Physically, the package only weighs 4 oz with batteries installed and it is only 4.3x2.2x1 small !

Channel Listener Specifications:
• Input: Digital signal input terminated into 75 Ohms. Accepts signals from 0 to 6V Peak-to-Peak.
• Signal Strength: Simple 0 to 9 signal strength indication. Ten 3 dB steps (total 30 dB range) . Level 5 = 1 Volt P-P nominal.
• VU meters: Direct-from-digital stream, no calibration ever required, Peak reading. 16 LEDS: Each representing 3dB. Top led = 0 to -1.5 dBFS, second LED= -1.5 to -4.5 dBFS (-3dB nominal), last LED = -43.5 to -46.5 (-45dB nominal).
• Headphone output: Mini stereo output jack for headphone 0.5volt P-P nominal output at -20dBFS input. Output is intended for audio stream verification use, not for high quality listening. 9 bit accuracy @ 48KHz PWM.
• Battery Operation: Two AAA cells: Uses either alkaline or rechargeable batteries. Operates down to 1.0 Volt.
• Power Consumption: 85mw (35ma @ 3.0 volts). Battery life ~10 Hours.
• Temperature: 0 C to 50 C (32 F to 125 F) non-condensing.

Note: This unit is the 48K model. Please call if you need a 44K model.
