The overall frequency responses for a mic input with 50dB gain (green), and line input at 0dB gain (blue). Note the greatly expanded amplitude axis, which exaggerates the 'bass bump' and HF resonance due to the input transformers. The -3dB points are around 6Hz and 75kHz for both, and flat within 0.5dB between 20Hz and 20kHz.



SPL Crescendo
A pair of frequency response measurements obtained with preamp gains of 50 and 70dB — the latter reveals an obvious reduction in bandwidth. Note that the extended scales exaggerate the effect for clarity; at 70dB the high frequency -3dB point falls to around 18kHz, whereas it's over 40kHz at 50dB gain.

An expanded frequency response plot which illustrates how the low‑end extension changes with gain. The blue curve is at 0dB gain, with a ‑3dB of 5Hz, while the green curve shows a ‑3dB point of about 18Hz at 60dB of gain. Both are perfectly acceptable, of course, but an interesting observation nonetheless. The high-end response is flat within 0.1dB to well beyond 80kHz at all gain settings for the analogue outputs. The digital output response is determined by the sampling rate, of course: the response is ‑6dB at half the sample rate.

A frequency response plot which shows the output level from a -50dBu input as the mic preamp's gain control is advanced in equal rotary increments. While the gain does increase slightly more quickly towards the clockwise extreme, overall the response is pleasingly linear and easily controllable.
