There are two meter options and the best Jensen output transformer (JT-11-BMQ) is also available as an option. Additional channels and options can be easily added later up to the total capacity of the mainframe.The M-1 was introduced in 1987 and while sonically identical to the M-2 there are a few control differences. The M-1 has a two-section gain-pot providing continuously variable adjustment in two overlapping ranges that are selected by the "High Gain" switch. The M-2 has a 16 position gain-switch with 1% metal-film resistors providing accurate and repeatable gain settings and since the "High Gain" switch isn't necessary it's available with either a 20 ohm mic switch OR a 20dB pad switch. 990 discrete op-amp - faster, quieter, more powerful and better sounding than typical monolithic op-amps. Elimination of all coupling capacitors from the signal path - results in less degradation of the audio signal. Dual range gain control and'high gain' switch - provides great feel and resolution for easy and accurate adjustments. All front panel switches are LED illuminated. Ground lift switch on each channel - helpful for eliminating ground loops. Toroidal power transformer with additional shielding - eliminates hum problems so no external power supply is needed.
Universal power supply - internal switch provides six primary voltage choices to accommodate use anywhere in the world. Chassis ground isolation switch - helpful for eliminating ground loops. VU-1 - Very accurate and informative 20 segment LED meter card with separate peak LED for monitoring preamp output. PK-1 - Peak LED metering only (not required if VU-1 is installed).
JT-11 - BMQ output transformer. Pin 2 Or pin 3 high - can be ordered either way and internal jumpers make changes in the field easy.
