The devilishly warm and dirty alternative to the pure Mic Amp Module. A front end that combines classic SSL character with our new Variable Harmonic Drive circuit, delivering a time machine of overdrive characteristics. Features:
- Electronically balanced ultra-high bandwidth Mic input with +20dB to +70dB gain control
- Hi-Z and Pad Switches on Mic Amp Input
- Dedicated Additional XLR Line Input
- Variable Harmonic Drive circuit adds a controllable blend of 2nd or 3rd Harmonic distortion
- Dedicated Trim control after the VHD stage
- Classic Listen Mic Compressor with fixed attack and release curves"_ ideal for drums
- High and Low-Pass Filters
Connection:The rear panel of the module carries theMic ("…IN') and Line input ("…LINE') XLRs alongwith a single output ("…OUT') XLR. The Line input and output operate at a nominal level of +4dBu although the gain of the Line input can be varied by a front panel control. Operation The X-Rack VHDMicmodule contains two separate input amplifiers
VHD MIC AMP Section:Normally, the Microphone input will be selected ("…LINE' switch released); pressingthe "…VHD IN' switch puts the "…DRIVE' control into the signal path, enabling this input to emulate the overload characteristics of a traditional valve/tube design butwith the ability to tailor the warmth or musicality. The "…DRIVE' control shapes the overload curve to provide a user controlled blend of 2nd or 3rd harmonic distortion. The gain of this input in either mode is continuously variable between +20dB and +70dB.
TRIM Section:The TRIM control provides Î+/-24dB of gain adjustment for either the Microphone or Line inputs; the Line level input can be selected in place of the Microphone signal by pressing the "…LINE' switch. The (Phase) switch reverses the phase of the selected input HF/LF Section: This section contains simple high and low pass filters as follows:HF (Low Pass): Frequency range 20kHz "– 3kHz ("–3dB point) Slope: 12dB/Octave LF (High Pass): Frequency range 15Hz "– 350Hz ("–3dB point) Slope: 18dB/Octave The two filters can be switched into circuit independently.
L COMP Section:The SSL "…Listen Mic' Compressor was, throughout the 1980's, the secret weapon in many producers sonic arsenal of recording techniques. Originally designed to prevent overloading the return feed from a studio communications mic, its fixed attack and release curves were eminently suitable for use on ambient drum mics.
