Remarks

• In the specifications, the 0 dBV value is referred to 1 Volt. Voltage levels are also given in brackets (0.316 V at - 10 dBV is rounded down to 0.3 V). To calculate the reference level at 0 dB = 0.775 V (e.g. 0 dBm in a 600 Ohm circuit), add 2.2 dB to the displayed dB value; e.g. - 10 dB reference: 1 V = - 7.8 dB reference: 0.775 V.

(fn. 1) These data were determined with TEAC testband MTT-111DN. (Fn. 2) These data were determined with TEAC test tape MTT-5561 (blank tape).
