SONODYNE SLA 3004

Product overview

The SONODYNE SLA 3004 is a two channel Class AB power amplifier from the SLA Series, delivering 600 W per channel into 4 Ω in a 2RU chassis.

The SLA Series is SONODYNE's range of 2RU power amplifiers: nine models, both dual and four channel, giving a broad choice of power output so a model can be matched to the power requirements of the application. All models can operate in three modes: dual channel, parallel (mono) and bridge. The SLA 3004 delivers 400 W per channel into 8 Ω, 600 W per channel into 4 Ω and 1200 W in 8 Ω bridged mode, with a signal to noise ratio of 101 dB and a frequency response of 20 Hz - 20 kHz (±0.5 dB).

Key features

• Soft start
• High SNR
• Low THD, IMD
• Heavy-duty power supply for high dynamic power
• Short-circuit, thermal, output DC, RF protection
• Variable-speed twin fan back-to-front cooling
• Twist-lock and binding post output connectors
• LED indicators for metering, status and operating mode
• Variable sensitivity selector

Power for every mode

The SLA 3004 runs in dual channel, parallel (mono) or bridge mode, selected at the rear with a 3 position slide switch (dual, mono, bridge). Into 8 Ω it gives 400 W per channel, into 4 Ω 600 W per channel, and bridged into 8 Ω 1200 W. A second slide switch sets the input sensitivity to 0.775 V, 1 V or 1.4 V.

Built for continuous duty

The SLA Series uses a large number of matched complementary devices in parallel with a linear transfer characteristic, for low distortion and a high safe operating area at elevated power levels. A heavy-duty power supply provides high dynamic power, a soft start eases switch-on, and the amplifier and load are protected against short circuit, output DC, thermal and RF faults. Cooling is by variable-speed twin fans, back to front.

Connections and front panel

Each channel has an XLR input with a link and both a twist-lock connector and a binding post output. The front panel carries clip, protect and signal LED indicators and a 42 detent rotary volume control per channel, as given in the official specification.

Workflow 1: Two channel (dual) operation

Installations driving 2 separate loudspeaker loads.

Connections

Setup

1. Rack the SLA 3004 (2RU).
2. Set the rear MODE switch to dual / stereo.
3. Connect each source to its channel input and each loudspeaker to its channel output.
4. Set each channel with its front volume control.

Tip: Into 4 Ω each channel delivers 600 W.

Workflow 2: Bridge mode

Systems that need more power into one 8 Ω load.

Connections

Setup

1. Set the rear MODE switch to bridge.
2. Feed the input used for bridge mode.
3. Connect the 8 Ω load to the bridged output.

Tip: Bridged into 8 Ω the SLA 3004 delivers 1200 W.
