Frontpanel

Fig. 2.

1. Rack Mounting Holes.

Two front panel mounting holes are provided on each mounting flange,

2. Fan Outlet Grills.

DSA Series amplifiers are cooled by two, rear-mounted fans, Cool air flows over the heat sinks and

exhausts through the rear grills, Make sure these outlets remain clear to allow unrestricted air flow,

3. Input Attenuators.

Whenever possible, set attenuators fully clockwise to maintain optimum system headroom. The input

attenuator controls (one for channel A, one for channel B) located at the front panel adjust gain for

their,

respective amplifier channels in all modes. See the specifications at the end of this manual for

standard

voltage gain and input sensitivity information. When operating the amplifier in bridged mode, both

attenuators must be in the same position, so the speaker load will be equally shared between the

channels.

4. Protect LED.

Indicates that the channel is in Protect mode (speakers disconnected by output relay),

5. Clip LED.

Illuminates at the clipping threshold, Continuous illumination also indicates that ACL (Active Clip

Limiting) protection circuitry is engaged,

6. Level Indicator.
