tone balance Flat if intensity is set fully anticlockwise.
The following values apply if intensity is
set fully clockwise:
balance left:
+12 dB at 50 Hz
balance center:
+9 dB at 50 Hz, and
+10 dB at 10 kHz
balance right:
-2 dB at 50 Hz and
+11 dB at 10 kHz
(shelf-type frequency response)
hf level +6/-19 dB at 10 kHz, effective on built-in
loudspeaker only.

Notes:
1. Input sensitivities refer to 220 watts into 8 ohms at full gain and
volume settings, neutral tone control settings (hf level in center
position, intensity in left position), and 1 kHz sine-wave test signal.
2. Output levels refer to 63 mV / 1 kHz at instrument input, unless
stated otherwise.
3. Bandwidth of tone controls refers to one half of dB-gain at center
frequency. For example, if center gain is –15 dB, then bandwidth is
the frequency band between the –7.5 dB points.
4. Equivalent input noise voltage obtained by measuring noise
voltage at speaker output and dividing by the effective voltage gain
of the amplifier. Full gain and volume settings, neutral tone control
settings, input shorted, frequency range 20 Hz – 20 kHz.
5. Compressor threshold refers to 1 dB gain reduction. Threshold
tolerance 3 dB. Ratio refers to 20 dB gain reduction. Ratio varies
with gain reduction due to soft-knee compression.
6. If required, the effect signal (from return) can be disconnected
from DI out by internal jumpers, even in the post switch position.
Specifications and appearance subject to change without notice.
