Dual-Channel Microphone and Instrument Preamplifier

• Discrete Class A solid stage

• Tube drive in three different intensity levels

• Flair presence enhancement in two switchable settings

• Switching inserts

• Pre-output limiter stage (extremely fast diode-based operation, perfect for A/D converter protection)

• VU metering with three different, switchable display ranges

• Front panel instrument input, separate rear-side microphone and line inputs

• Phantom power, phase reverse, pad and high-pass filter (50Hz)

• Frequency response ‹10Hz to 90kHz (-3dB)

• THD+N (Input level -30dBu, 30dB Gain) 0,016%

• Noise (A-w., R=40Ohm, 30dB Gain) -91,2dBu

• Dynamic range (30dB Gain) 110dB

• E.I.N. 128dBu

• Max. output level (sym., XLR+Jack) +26,8dBu

• Slew rate solid state stage 200V/µs
   

AD Converter Module 1090

• 24-bit converter supporting sample rates up to 192 kHz

• Highly accurate quartz oscillators ensure a clean, low-jitter master clock

• SPDIF output with both coaxial and optical connectors

• Switchable internal sample rate of 44.1, 48, 88.2 and 96 kHz

• Sample rates of 32, 176,4 und 192 kHz are set by external syncronization

• The converter can be synced to other digital devices via a SPDIF input

• The internal oscillators are automatically disabled when an external clock signal is present to prevent interference
   

Lundahl Transformers

• Transformers can be used as an alternative to electronic balancing stages in the inputs and outputs

• Bass and fundamental range becomes rounder, fuller and gets more pressure

• High and overtone range sounds a bit silkier and more present

• When equipped with input and output transformers and completely symmetrical cabling, no voltages can enter the device via the signal connections that could cause damage

• Signal transmission is inductive and thus electrically isolated

• No hum is guaranteed

• Drives very long cable runs (advantageous for live applications)
