Effects
Internal efx
Two independent digital effects for
ch. 1-2 and ch. 3-4.
Presets for each unit:
1. reverb
2. reverb with longer predelay
3. delay, repetitive (320 ms)
4. chorus
External efx Parallel effect loop, see fx send and fx return
effects pan
Blends effect between ch. 1 and 2, or ch. 3 and 4
respectively. The direction of rotation is reverse
for the external effect.

Definitions
Rated conditions
• nominal input voltage at input under test
• master fully clockwise
• bass / middle / treble / pan centered
• effects level fully anticlockwise
• gain of unused inputs fully anticlockwise
• gain of input under test adjusted to nominal output voltage
at line out.
Nominal input voltage:
Condition for specifications, if not stated otherwise.
Minimum input voltage
Input voltage required for nominal output ratings with
maximum gain and volume settings.
Maximum input voltage
Input voltage that does not cause distortion more than rated
THD+N, suitable control settings provided.
Nominal output voltage or power
refer to rated conditions.
THD + N
Total harmonic dist noise, with input voltage reduced by
10 dB after setting up rated conditions.
Signal / noise ratio
Ratio of nominal output voltage to output noise voltage. Source
voltage reduced to zero after setting up rated conditions.
Equivalent input noise voltage
Noise voltage at output terminals divided by gain of amplifier.
Source voltage reduced to zero after setting up rated conditions.
Residual noise
Output noise with minimal gain and volume settings.
Adaptive limiter
Maintains constant headroom regardless of power supply
fluctuations.
General
Signal voltages are RMS values. Test signal sine 1 kHz sine unless
stated otherwise. Noise measured from 20 Hz to 20 kHz. Noise
stated for a specific input implies that all other inputs are not
used. Sound pressure level (SPL) based on specification by
loudspeaker manufacturer.
Specifications and appearance subject to change without notice.
