NOTES

I

Device Under Test (DUT) is bypassed, decoupled and dc-coupled as shown in Figure 17 (no de-emphasis circuit).

Performance of the right and left channels are identical (exclusive of “Interchannel Gain Mismatch” and “Interchannel Phase Deviation” specifications).

Attenuation setting is 0 dB.

Values in bold typeface are tested; all others are guaranteed, not tested.
