1. Power switch [ ON / OFF]
Power is switched on and off with each
depression of this switch.
2. Power indicator [POWER]
Lights blue when the power is switched on.
3. Input level controls [CH 1/BRIDGE, CH 2]
Adjust the input level of each channel.
4. Ventilation panel (Air Vent)
A filter is located inside the ventilation panel.
To clean the filter, remove the ventilation panel.
(See p. 15; Cleaning the Filter.)
5. Indicators [INPUT, OUTPUT, PEAK, PROTECT]
The indicators are as follows from left to right:
• Input indicator [INPUT]
Lights green regardless of the input level
control setting when an input signal level
exceeds about –20 dB.
• Output indicator [OUTPUT]
Lights yellow when an output level exceeds
about 1 W at an 8 Ω load (DA-250D) or 19.6 Ω
load (DA-250DH).
• Peak indicator [PEAK]
Lights red when an output signal clips
(distortion occurs).
• Protection indicator [PROTECT]
Lights red when the protection circuitry is
activated. (See p. 14; Protection Operation
List.) When the power is switched on, this
indicator lights for about 2 seconds and then
extinguishes.
When a bridge connection is made
When Channels 1 and 2 are bridge-connected
(BRIDGE ON/OFF switch (9) is set to ON), the
CH 1/BRIDGE level control adjusts the input
levels of Channels 1 and 2. In this event, the
CH 2 level control cannot be used.
