MAKING ADJUSTMENTS AND FITTING SPARES

CAUTION: THE FOLLOWING SECTION IS FOR USE BY QUALIFIED SERVICE PERSONNEL ONLY. TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE THE TOP FASCIA OR THE FADER PANEL TO PERFORM ANY SERVICING OR OTHER TASKS, UNLESS YOU ARE QUALIFIED TO DO SO.

BEFORE REMOVING THE TOP FASCIA OR THE FADER PANEL ENSURE

THE UNIT IS DISCONNECTED FROM THE MAINS SUPPLY.

ONLY REMOVE THE ALLEN SCREWS INDICATED ON THE DIAGRAM OPPOSITE.

WARNING: DO NOT OVER-TIGHTEN THE SCREWS AFTERWARDS.

It is necessary to remove the top panel fascia in order to carry out one or more of the following tasks:

Setting the pre-trim pads during installation, and setting of the gain stages / output pads.

Adjusting the external mute mic level control

It is necessary to remove the fader panel only in order to replace any of the faders, including the cross-fader.

Removing The Top Panel Fascia

To remove the top panel fascia proceed as follows:

Pull off all the pot knobs.

Undo the 9 (for 1605) or 8 (for 1603) retaining Allen screws using a 2mm Allen key. The fascia can now be lifted clear of the subframe underneath. Take care not to bend the panel.

The diagrams opposite show views of the 1605 mixer without top fascias fitted. The 1603 is similar but has fewer retaining screws.

Setting The Pre-trim Gain Stages

These pads are used to adjust the input level to individual channels, e.g. to reduce the input when using a piece of equipment with a high output level.

There are 2 pads on each of the input channels. The +14dB gain stage switch is nearest to the faders, and the -10dB pad is nearest to the rear panel. The switches are push-on push-off types. The pads are in-circuit when the switches are depressed. If both switches are inadvertently depressed the -10dB pad is selected. The +14dB selection is designed to boost the signal from low level portable devices such as mp3 players.

Setting The Master Output Pads

There are two pads on the master outputs, -10dB and -20dB. Depress the -10dB to select the -10dB pad, depress both switches to select the-20dB pad: if only the -20dB switch is depressed no pad will be selected.

Adjusting The External Mute Mic Level Control

If the external mute facility is going to be used, the installation engineer can check and adjust the level at which the DJ channel 1 mic signal will appear at the master outputs. To simulate an external mute condition depress the mute test button. The main output will then only be the output from DJ channel 1. Under the external mute condition its level at the output is unaffected by any mixer control except for the preset ext mute mic level pot. When the pot is fully anti-clockwise the mute the signal.

Removing The Fader Panel

To remove the top panel fascia proceed as follows:

Pull off the cross-fader knob only (the channel faders are attached to the panel and will lift away with it).

1605, 1603 specifications

The SoundCraft 1603 and 1605 are renowned analog mixing consoles well-regarded in both live sound environments and studio settings. These mixers offer exceptional sound quality coupled with intuitive operation, making them a popular choice among audio engineers and musicians alike.

The SoundCraft 1603 is a 16-channel mixer featuring 3 buses, while the 1605 amplifies this with 16 channels and 5 buses, providing increased routing flexibility. Each channel is equipped with a high-quality microphone preamplifier, which delivers a warm, rich sound. The preamps feature a low-cut filter that aids in eliminating unwanted low-frequency noise, further enhancing audio clarity.

Both models come with an integrated 3-band EQ on each channel, complete with adjustable high, mid, and low frequencies. This allows for precise tone shaping, enabling users to sculpt their sound to fit various musical styles and requirements. The mid-band also features a sweepable frequency, providing the ability to target specific problematic frequencies in live settings, enhancing the overall mix.

Advanced technologies implemented within these consoles include the use of internal components that reduce noise levels and improve overall audio fidelity. The mixers are designed with ruggedness in mind, ensuring they withstand the rigors of live performance while providing the reliability necessary for studio applications.

Additional features that stand out include a range of auxiliary sends, allowing for flexible routing options for effects and monitor mixes. The mixers also support phantom power, making them ideal for use with condenser microphones. The user-friendly layout ensures quick access to all controls, allowing engineers to focus on mixing without unnecessary distractions.

Another key aspect is the mixer’s compact design, making it suitable for small venues, mobile setups, and studio environments where space is a premium. The sturdy construction and high-quality components ensure longevity, a significant advantage for professionals who rely on consistency in their equipment.

In summary, the SoundCraft 1603 and 1605 mixing consoles are excellent choices for those seeking high performance in a compact and user-friendly package.
