The Input Section |
|
 |
| The mic amp uses Mr. Rupert Neve’s TLA (transformer-like amplifier). It’s exemplary overload capability and wide dynamic range allows the mic amp to adapt to the full spectrum of mic techniques. Phantom power, fine trim and phase reverse are provided. |  |
|
The Filters |
|
|
| The high pass filter allows the removal of unwanted low frequency noise components, for example, rumble and hum. The low pass filter’s extended range allows it to remove unwanted distortion in the conventional audio band caused by components in the inaudible upper frequency bands. |  |
|
The Low Frequency Section |
|
|
| The LF band has the frequency range of 30-300Hz, with two ranges of cut/boost control. ‘Bell’ mode provides a Q factor of approx. 0.7. It is used to subtly control the signal around the set frequency with attenuation to either side. The ‘Glow’ switch subtly alters the response curve shape to give ‘warmth’ to a sound without changing its character. |  |
|
The Low Mid Frequency Section |
|
|
| The LMF band has the range 30Hz-1kHz. Q is variable between 0.65-2. Low settings provide a gentle enhancement while higher settings produce a harsh resonant sound. ‘Notch’ converts the section into a band stop filter creating a narrow attenuation band with minimal effect on the rest of the sound. |  |
|
The High Mid Frequency Section |
|
|
| The HMF band operates over the frequency range of 500Hz-4.5kHz. In common with the other frequency sections it has a cut/boost of +/-18dB. For finer control of complex programme material this range can be reduced to +/-9dB. Q control and ‘Notch’ operate in an identical manner to the LMF section. |  |
|
The High Frequency Section |
|
|
| The HF band operates over the range 2-21kHz. Bell/Shelf mode is identical to the LF, a Q factor of 0.45 is used. Shelf mode raises or lowers the frequencies above the turnover point subtly altering the tonal balance without affecting the higher harmonics. ‘Sheen’ subtly alters the response curve shape to give ‘warmth’ to a sound without changing its character. |  |
