The Maselec STM-822 offers the highest quality analog summing available for recording and mastering applications. The STM-822 provides 8 stereo inputs and 2 independent stereo outputs with separate amplifiers. The signal path is completely balanced, and there are only 3 amplifiers in any path.
The stereo outputs provide separate amplifiers capable of driving a 600 ohm load with a maximum level of +29dBu, and output noise of -100dB under normal operating levels and, output noise lower than -88dBu with full gain and all inputs open (much lower than the summed noise of 24 bit converters).
The level controls are precision 1/2dB stepped rotary pots providing ±5dB adjustment. Cut and Solo functions are relay activated with a common relay for each stem.
Maselec STM-822's features
Eight stereo inputs.
Two stereo outputs with separate amplifiers; both can drive 600 ohms and be unbalanced.
The signal path is completely balanced from input to output.
Only three, very wide bandwidth, amplifiers in the signal path.
Cut and Solo, with one common gas filled relay, for each input.
Output noise lower than -88dBu with maximum gain and all inputs open (matches converters with 120dB dynamic range).
Output noise lower than -100dBu with all inputs open and gain set to -10dB (typical mix setting).
VU meters with switch for 0VU = +4dBu or +10dBu.
Signal present LED for each input.
Gain adjustable in 1/2dB steps between –15dB and +5dB.
Studio Economik New 500 series preamp from Geoffrey Daking featuring vintage Trident A Range tone, Jensen input transformer and Class A circuitry. The variable high pass filter is indispensable for tracking sessions!
