tone balance No eect if intensity is set fully to the left. The following

values apply if intensity is set fully to the right:

balance left:

+10 dB at 50 Hz

balance at center position:

+8 dB at 50 Hz, and +7 dB at 10 kHz

balance right:

-3 dB at 50 Hz and +8 dB at 10 kHz

(shelf-type frequency response in all cases)

hf level +6/-19 dB at 10 kHz, eective on built-in

loudspeaker only.

General

Cabinet 0.7“ (18 mm) birch plywood

Finish waterbased acrylic, black spatter nish

Dimensions 500 mm (19.7 “) high

420 mm (16.5 “) wide

350 mm (13.8 “) deep

Weight 23,5 kg (51.7 lbs)

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 out-

put and dividing by the eective voltage gain of the amplier. 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.
